Description
Cosmology and Particle Physics at the Excellence Cluster Universe - One year of research at the Excellence Cluster Universe: For the first time the Cluster hosts its annual ‘Science Week’. From 3 to 7 December 2007 Cluster scientists will present their current research work. In about 40 talks they will cover issues from the seven research areas (RAs) of the Cluster – ranging from the origin of the Universe to the development of heavy elements and structures. On 6 December the RA coordinators will provide a general overview of the topics and progress of their work groups. The Science Week is directed to all scientists who want to gain insight in the current state of research in cosmology.

      Metal poor stars as tracers of cosmic nucleosynthesis 45m New seminar room

      Giessenbachstraße 85748 Garching
      The low end of the Galaxy halo stellar metallicity distribution is characterized by the presence of a large population of peculiar composition objects. In particular, a large fraction of very metal poor stars show large overabundances in C. It is estimated that at least 20% of stars with [Fe/H]<-2 have [C/Fe]>1, and such fraction likely increases with decreasing metallicity (the two most metal poor stars known have both extremely high C overabundance). Most of these stars are characterized by various degrees of n- capture elements enrichments (s and/or r), and some show also very large overabundances of alpha- elements. It is now clear that the investigation of such objects, aimed to explain the origin of these peculiar abundance pattern, and of their extremely high incidence is crucial to the understanding of the Early Galaxy formation and evolution. I will present the largest so far sample of metal poor, C-rich stars with high resolution analysis, describe our present knowledge of their formation mechanisms as well as discuss the constraints and the implications they provide our understanding of the mechanisms that enriched scenario the Early Galaxy, and in particular low Z AGB nucleosynthesis.

      Giessenbachstraße 85748 Garching
      I will describe how the chemical compositions of stars can be used to probe stellar, galactic and cosmic evolution. Besides tracing things like stellar nucleosynthesis and the history of the Milky Way Galaxy and its different stellar populations, the elemental information imprinted in stellar spectra can also shed light on for example the baryon density of the Universe and perhaps even the existence of supersymmetric particles. Unfortunately the stellar elemental abundances can not be directly read off from the observed spectra but require realistic modelling of the stellar atmospheres and the spectrum formation, something my group has worked very hard on improving. Finally I will describe our ongoing and planned efforts in discovering and understanding the very first stars born in the Universe.

      Massive stars are major agents to influence their surrounding gas: Winds and supernovae blow cavities and inject turbulence, and also eject freshly- produced and partially radioactive isotopes, ionizing radiation produces free electrons. We discuss how we can test our understanding of these processes on astronomical observations.

      The thermodynamic properties of a gauge theory without quarks are derived using a string (gravity) formulation for a temperature window 1.2 T_c – 3 T_c. The results are in good agreement with available lattice simulations. As a cross-check, we calculate the spatial string tension. Finally, we make some predictions about SU(N) gauge theories.

      BOREXINO, a detector for low energy neutrinos, is operational since summer 2007. The experiment is aiming for low energy solar neutrinos, supernova neutrinos, and terrestrial antineutrinos. The performance of the detector is as well a basis for the design of the next generation neutrino detection in LAGUNA, and in particular for LENA (low energy neutrino astronomy). The latest results from BOREXINO will be presented and discussed in this context.

      Suzaku observations of NGC 4395 20m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      NGC4395 harbors the lowest luminosity type-I AGN, known to exhibit strong X-ray variability, in a bulge- less dwarf host. The low black hole mass (~10^5 solar masses) makes this object of great interest for the formation of massive black holes and the mass- scaling of AGN phenomena. We observed NGC4395 with Suzaku for the net exposures of 100 ks and 83 ks with the XIS and the HXD-PIN, respectively. A significant signal above 10 keV was detected for the first time from this object with the HXD-PIN. The 2-10 keV mean flux remains similar to the previous values, suggesting no large power in variability on time- scales of years. This and the observed rapid, strong X- ray variability (the characteristic time-scale of a few 100 s and the rms amplitude as large as 85%) agree with the expected behaviour of a low mass black hole. The rms amplitude decreases towards higher energies but this energy dependence appears to be weaker than in the previous XMM-Newton observation. The 2-10 keV spectrum is very hard as usual, and can be approximated by a power-law with photon-index of ~1. This hard spectrum extends up to 20 keV and then rolls over. The hard spectrum is partly due to a thick warm absorber with n_H of 10^23 cm^-2, but the soft photons below 1.5 keV are more absorbed than previously observed. This is likely due to a decrease of the ionisation parameter, hence increasing the OVII opacity. A relatively weak Fe K line is present which peaks at 6.4 keV with a small red wing.

      Gamma-ray burst afterglows with GROND 25m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      It is general believe that long Gamma Ray Bursts (GRBs) are connected to the death of very massive stars and are detectable up to redshifts of 15 to 20. However, identifying GRB afterglows at high redshifts remained difficult as it requires rapid and sensitive near-IR capabilities. I will introduce the Gamma Ray Burst Optical and Near Infrared Detector (GROND), an imager capable of synchronous imaging in seven photometric bands (g to K) and dedicated to fast follow up observations of GRB afterglows. I will present recent results obtained with GROND, including the light curve and SED of GRB070802.

      Giessenbachstraße 85748 Garching
      One of the main goals of the XMM-Newton COSMOS survey is to provide a comprehensive characterization of the multiwavelength properties of AGN selected in the X-rays over a wide range of redshift and luminosities, and eventually, build up the first bolometric selected AGN sample, fulfilling the promise of many years of multi-wavelength studies of quasars. Here I present the results obtained by exploiting all the data available from the XMM- COSMOS program (including ACS morphological information and extensive optical spectroscopy). In particular, I will focus on: 1) the survey strategy and design; 2) the source counts in the hard band (5-10 keV) band; 3) the results on the mid-infrared (Spitzer/IRAC + MIPS) properties of the obscured AGN population; 4) photometric + redshifts for AGN; and 5) the number density of high redshift QSOs.

      In the coming years a number of very wide angle, deep surveys will enable us to carry out detailed analyses of the large scale distribution of galaxies, that have not been feasible before, and a wealth of information about the nature of the universe - its mass content, the ratio of luminous to dark matter, and last not least its dark energy density - is encrypted in the distribution of matter in space(time). In my talk I will review how we will use different statistics that measure clustering in order to investigate the equation of state of dark energy, and what else we can learn from galaxy clustering.

      Cryogenic composite detectors for the dark matter experiments CRESST and EURECA 20m New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      Weakly Interacting Massive Particles (WIMPs) are candidates for non-baryonic Dark Matter. WIMPs are supposed to interact with baryonic matter via scattering off nuclei producing a nuclear recoil with energies of a few 10 keV with a very low interaction rate of ≤10−6 events per kg of target material and day in the energy region of interest. The Dark Matter experiments CRESST (Cryogenic Rare Event Search with Superconducting Thermometers) and the EURECA (European Underground Rare Event Calorimeter Array) project are aimed at the direct detection of WIMPs with the help of very sensitive modularised cryogenic detectors that basically consist of a transition edge sensor (TES) in combination with a massive absorber crystal. Presently CRESST is increasing the absorber mass up to some kg delivering the basis of the EURECA project that is aimed at a tonne scale of multi target cryogenic detectors. The development of these cryogenic detectors and the potential ton scale production are investigated in the Munich group of the CRESST collaboration. [abridged]

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      String theory predicts the existence of dynamical extended objects called D-branes, which can be seen as electric or magnetic sources of corresponding fluxes and, at low energy, are described by (non- abelian) gauge theories. D-branes and fluxes enter many string theory models of an effective four- dimensional physical universe and in particular those with minimal supersymmetry, to be eventually spontaneously broken. I will discuss some general features of such minimally supersymmetric models in type II string theories. A unifying and elegant geometrical structure emerges, which turns out to be deeply related to the physics of D-branes.

      How to discover the Higgs boson with the ATLAS detector at the LHC 25m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      The Standard Model of particle physics predicts the existence of a new, so far unobserved particle, the Higgs boson needed to explain particle masses different from zero. The ATLAS experiment has been designed to search for the Higgs boson over its full allowed mass range from 114 to about 800 GeV in proton-proton collisions of 14 TeV center-of-mass energy at the Large Hadron Collider (LHC). After the LHC startup next year, several thousand Higgs bosons are expected to be produced in the collisions every year. Characteristic Higgs boson decays are, however, hidden in a many orders of magnitude higher rate of Standard Model background processes which have to be precisely predicted. Due to the high- resolution detectors and elaborate selection criteria, sufficient background rejection can be achieved. The discovery reach of the ATLAS detector for the Higgs boson in different decay channels is currently being reevaluated. Higgs decays into four leptons provide a clear signature for Higgs masses above 200 GeV. For lower Higgs boson masses favoured by the electroweak precision data combination of several decay channels is necessary for an early discovery of the Higgs particle.

      Neutrinoless double-beta-decay could be the key to understanding the nature of the neutrino: If observed it would prove its Majorana-nature and the half-life of the decay would be a direct measure of the yet unknown absolute scale of the neutrino mass. The GErmanium Detector Array (GERDA) at the Gran Sasso Underground Laboratory in Italy is designed to search for neutrinoless double-beta-decay of the isotope 76Ge. Germanium crystals enriched in 76Ge will be submerged directly into their ultra pure cooling medium that also serves as a radiation shield. Status and prospects of the experiment will be presented.

      Higgs bosons contribute as virtual states through quantum corrections to the predictions for precision observables in the electroweak theory. Precision data thus constrain the mass of the Higgs boson. Recent improvements in the calculation of electroweak precision observables are discussed that have considerable impact to pinning down the Higgs boson mass and to set the stage for Higgs discoveries at future colliders.

      Giessenbachstraße 85748 Garching
      From observations of the cosmic star-formation history, as probed by young galaxies at z>3 (that is during the first 15% of the age of the Universe), one can infer the cosmic density of heavy elements, like Oxygen and Iron, expected by z~3. However, searches for such metals at z~3 have only been able to account for 10-20% of the amount expected - this has been coined 'the Missing Metals Problem'. In the talk I will discuss possible reasons for this controversy, and also where the 80- 90% 'missing metals' might be located.

      Little Higgs models offer an alternative way to the solution of the little hierarchy problem. Particularly interesting is the Littlest Higgs model with T-parity (LHT). The talk's main attention is paid to the motivation of the LHT and an analysis of the impact of the additional particles introduced in the framework of the LHT on a wide array of lepton flavour violating (LFV) decays. Finally, it is pointed out how parameter independent ratios of branching ratios of LFV decays can be used to distinguish the LHT from SUSY at low energy experiments.

      The spin structure of hadrons in terms of quarks and gluons is an important domain of modern particle physics. Of particular interest is the origin of the total spin of the proton, summarized in form of the proton spin sum rule. Other exciting questions concern possible correlations of spin, orbital and coordinate degrees of freedom inside hadrons. Lattice Quantum Chromodynamics provides a means to address these questions starting from first principles. I will discuss some of the most interesting insights into the longitudinal and transverse spin structure of the proton obtained from recent lattice QCD simulations. I will also show that the pion, despite being a spin-zero particle, has a surprisingly non-trivial spin structure.

      Understanding the origin of cosmic acceleration from the growth rate of large-scale structure 45m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      I will review the current status of studies of the large- scale structure of the Universe, in the light of the surprising evidence for acceleration of the cosmic expansion rate. Deep redshift surveys with 8-m class telescopes are just starting to be large enough to estimate 'global' quantities that directly probe the parameters of the cosmological model at z~1, in particular in its dark sector. I will show how measurements of linear redshift-space distortions due to galaxy coherent motions can be used to measure the evolution of the growth rate of cosmic structures f(z) at different epochs. Combined to estimates of the cosmic expansion rate H(z), e.g. from Type Ia Sne or Baryonic Acoustic Oscillations, these observations can pinpoint the physical origin of the accelerated expansion, distinguishing true 'dark- energy' models from modifications of the gravitation theory.

      Giessenbachstraße 85748 Garching
      The gravitational lensing of pregalactic HI could be a tremendously important tool for doing cosmology in the future. Low-frequency radio observations of neutral hydrogen during and before the epoch of cosmic reionization will provide hundreds of quasi- independent source planes. These planes can be used to reconstruct the projected mass distribution of foreground material, effectively imaging dark matter back to very early times. A wide-area survey of 21 cm lensing would provide very sensitive constraints on cosmological parameters, in particular on dark energy. These are up to 20 times tighter than the constraints obtainable from comparably sized, very deep surveys of galaxy lensing although the best constraints come from combining data of the two types. If the reionization epoch is at z ~ 9 huge amounts of cosmological information will the accessible. The planned Square Kilometer Array (SKA) should be capable of mapping the mass with a resolution of a few arcminutes depending on the reionization history of the universe and how successfully foreground sources can be subtracted. The Low-Frequency Array (LOFAR) might be able to measure an accurate matter power spectrum if the same conditions are met.

      Addressing the challenges of future collider detectors 45m New seminar room

      Giessenbachstraße 85748 Garching
      The International Linear Collider ILC is currently planned as a machine to provide precision measurements at the Terascale, following up the discoveries likely to be made at the Large Hadron Collider LHC. To achieve the anticipated precision, the detector systems at such a future facility have to go well beyond the present state of the art. I will highlight the physics potential of the ILC, and discuss challenges for the detector system arising from this physics program. I will focus on detector development aimed at meeting these challenges, in particular in the area of vertex detectors and calorimetry. In these areas, scientists at the Cluster contribute to establish concepts for the next generation of high energy particle physics experiments.

      Supersymmetry is a well-motivated particle theory beyond the Standard Model which predicts new particles yet to be discovered. The talk will review the possible experimental signatures of supersymmetric particles produced at the Large Hadron Collider (LHC), with a special focus on the first years of data.

      Is dark matter supersymmetric? 25m New seminar room

      Giessenbachstraße 85748 Garching
      The identity of dark matter is one of the greatest puzzles of our Universe. Its solution may be associated with supersymmetry which is a fundamental space-time symmetry that has not been verified experimentally so far. In many supersymmetric extensions of the Standard Model of particle physics, the lightest supersymmetric particle cannot decay and is hence a promising dark matter candidate. For particularly well-motivated candidates, I will discuss primordial production mechanisms, cosmological constraints, and prospects of experimental identification.

      I will explain why supersymmetry is a natural, and perhaps necessary, ingredient of string theory, and what that implies for string phenomenology at the TeV scale . I will then shortly address the question of whether we can do string theory without supersymmetry.

      Quantization of motion in curved manifolds 45m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      One of the most interesting and difficult issues of cosmology concerns understanding the very early Universe at the Planck scales. The main obstacle in a way of getting a clear notion of this phase is the necessity to have a fully quantized theory of gravity. And since general relativity, which we believe to describe gravity correctly at the classical level, is a theory with constraints, it seems to be of a great importance to study carefully all the characteristic features of constrained theories quantization. To clarify some of the relevant points, we use in this talk a dynamical system which is much simpler than the gravity theory but can serve as a good toy model for understanding some of the problems.

      Massive Black hole binaries for the ages 45m New seminar room

      New seminar room

      Max-Planck-Institut für extraterrestrische Physik, Garching

      Giessenbachstraße 85748 Garching
      I will review scenarios for the assembly of massive black holes (MBHs) that trace their hierarchical build- up far up in the dark halo merger tree. The first active galactic nuclei may have formed 200 Myr after the big bang in one million solar mass halos. I will discuss the conditions under which MBHs become incorporated through a series of mergers into larger and larger halos, sink to the center owing to dynamical friction, accrete a fraction of the gas in the merger remnant to become supermassive, form a binary system, and eventually coalesce. The spin distribution of MBHs is determined by gas accretion, and is predicted to be heavily skewed towards fast- rotating Kerr holes, already in place at early epochs, and not to change significantly below redshift 5. Decaying MBH binaries will eject hypervelocity stars, shape the innermost central parsec of galaxies, and should be detected in significant numbers by LISA.

      The realization of background independence in Topological String Theory leads to a set of equations which have to be satisfied by the topological string partition function. These so called holomorphic anomaly equations lead to interesting insights into the structure of the partition function and provide an efficient calculation tool. The so computed partition function carries information on mathematical invariants as well as on string dualities.
