The Excellence Cluster ORIGINS hosts their annual Science Week this year at beautiful Kloster Seeon in Upper Bavaria.
The agenda will include overview and science highlight talks from our research units, connectors and infrastructures, our annual General Assembly, PhD Awards talks and Laudations, Seed Money posters and a new election of cluster coordinators as well as ORIGINS 2 planning sessions.
Scientific Organization Committee: Dieter Braun, Andreas Burkert, Barbara Ercolano, Laura Fabbietti, Stephan Paul, Petra Schwille and Jochen Weller
Riccardo's thesis focused on accretion of matter onto black holes of different masses. It studied one of the most known, yet still unexplained, observational relations in active super-massive black holes and compared it with observations of their stellar-mass relative. It made use of the newly-launched eROSITA X-ray telescope to study a new class of transient accretion events around black holes of intermediate masses.
The Twinkle Space Mission is a space-based observatory that has been conceived to measure the composition of solar system objects, exoplanets, protoplanetary disks and stars. The satellite is based on a high-heritage platform and will carry a 0.45 m telescope with a visible and infrared spectrograph providing simultaneous wavelength coverage from 0.5 - 4.5 μm. The spacecraft will be launched into a Sun-synchronous low-Earth polar orbit and will operate in this highly stable thermal environment for a baseline lifetime of seven years.
This talk will provide an overview of Twinkle’s capabilities and discuss the broad range of targets the mission could observe, demonstrating the huge scientific potential of the spacecraft. Additionally, the work of the Founding Members will be highlighted, showing the initial interest of the survey members
Liquid water plays an active role in shaping molecular evolution during the Origin of Life. Water cycles under a Hadean CO2 atmosphere create fluctuations in the salinity, pH and temperature that drive the replication and evolution of long DNA sequences. The water cycles at the millimeter-scale also affect the assembly, division and selection of coacervate protocells.
An important ongoing program in high-energy nuclear physics is the exploration of the phase diagram of quantum chromodynamics (QCD) at large values of temperature and/or densities. In that regime, QCD predicts the existence of a quark-gluon plasma (QGP) state, in which quarks are deconfined and can move freely over distances comparable with the size of hadrons. Results from heavy-ion collision data at LHC are consistent with the scenario in which QGP
undergoes collective expansion, dominated by its hydrodynamic response to the anisotropies in the initial state geometry — a phenomenon known as anisotropic
flow. Properties of QGP are typically portrayed by specifying its
transport properties (e.g. shear or bulk viscosities), or its equation of state.
In this talk, anisotropic flow results obtained from multi-particle
correlation techniques are presented. Special focus is given to recently developed new flow observables (symmetric and asymmetric cumulants of multi-harmonic flow correlations, symmetry plane correlations) [1,2], each of which by
design extract new and independent information about QGP properties. By using Bayesian parameter estimation methods, it is demonstrated how the temperature-dependent
specific shear and bulk viscosity of QGP can be constrained from experimental data [3,4].
