  3. 37. Quantization of generalized massive electrodynamics
    Veronica Errasti Diez
    22/11/2021, 13:55

    In 1936, Alexandru Proca put forward the idea of a massive photon, as a means to resolve the infinite electromagnetic energy of a point charge in Maxwell's theory. Proca's proposal quickly became and remains the theoretical cornerstone to non-linear optics.

    In 2014, Gianmassimo Tasinato and, independently, Lavinia Heisenberg introduced the notion of a generalized massive photon, classically...

  4. 9. The multi-scale baryon cycle from clouds to galaxies
    Diederik Kruijssen (Univ. Heidelberg)
    22/11/2021, 14:20

    The cloud-scale physics of star formation and feedback represent the main uncertainties in galaxy formation and evolution simulations. I will present our group's efforts towards overcoming this problem by using empirical constraints on the molecular cloud lifecycle to motivate a new generation of sub-grid models in galaxy simulations. Specifically, I will show how we can use the multi-scale...

  5. 73. Galactic dust tomography
    Torsten Ensslin (MPA)
    22/11/2021, 14:50

    Galactic dust grains are aggregations of molecules in the interstellar medium, which form preferentially at denser locations. Dust plays a central role in galactic physics, it obscures the view on stars by its optical light absorption and obfuscates our view on the cosmic microwave background by its emission of the absorbed energy at longer wavelength. The structure of dust clouds as well as...

  9. 49. ALICE: A new laboratory to investigate and constrain exotic hadron-hadron interactions
    Dimitar Mihaylov (TUM)
    22/11/2021, 16:50

    The study of the strong interaction is a rich subject, where the traditionally employed experimental techniques, such as scattering experiments, are not well suited to study baryons with strange quark contents (hyperons). Thus, it is difficult to constrain existing effective models, which in turn prohibits the deeper understanding of the nuclear equation of state (EoS). The latter describes...

  11. 65. Are leptons less universal than we thought ?
    Thomas Kuhr (LMU)
    22/11/2021, 17:25

    In the standard model of particle physics the couplings of leptons are assumed to be equal. While this is supported by many measurements, recent results challenge the assumption of lepton flavor universality. The experimental hints for new physics contributions to lepton couplings will be reviewed and approaches pursued at the ORIGINS cluster to address the open question of lepton flavor...

  14. 51. PhD Thesis: The Origin of High-Energy Cosmic Particles: IceCube Neutrinos and the Blazar Case. Probing multi-messenger data by combining techniques from astrophysics, machine learning, and statistics
    Theo Glauch (TUM)
    23/11/2021, 09:10

    Between the galaxies and stars, our universe is filled with charged particles reaching energies up to a million times higher than those at human-made particle accelerators. The origin of those cosmic-rays remains, however, largely a mystery. In my work, I have used neutrinos as a tracer for the production of cosmic rays in extragalactic environments. In contrast to cosmic rays, neutrinos...

  19. 4. Exploring the high-redshift PBH-Λ CDM Universe: early black hole seeding, the first stars and cosmic radiation backgrounds
    Guenther Hasinger, Director of Science, ESA, Madrid, (ESA, Director of Science)
    23/11/2021, 11:30

    We explore the observational implications of a model in which primordial black holes (PBHs) with a broad birth mass function ranging in mass from a fraction of a solar mass to ∼106 M⊙, consistent with current observational limits, constitute the dark matter component in the Universe. The formation and evolution of dark matter and baryonic matter in this PBH-ΛCDM~ Universe are presented. In...

  20. 11. Simulations of dark matter with frequent self-interactions
    Moritz Fischer (University of Hamburg)
    23/11/2021, 14:00

    Self-interacting dark matter (SIDM) is promising to solve or at least mitigate small-scale problems of cold collisionless dark matter. N-body simulations have proven to be a powerful tool to study SIDM within the astrophysical context. However, it turned out to be difficult to simulate dark matter models that typically scatter about a small angle, for example, light mediator models. We...

  22. 54. Cosmological insights from the Dark Energy Survey
    Daniel Gruen (LMU Munich)
    23/11/2021, 14:55

    The Dark Energy Survey has recently presented cosmological results from weak lensing and galaxy clustering two-point functions using data collected in the first three years of operations. The combination of area (>4000 deg^2) and depth (100 million lensing source galaxies observed) significantly exceeds the previous state of the art, requiring the development of new methodology in several...

  23. 28. The Hubble Tension
    Sherry Suyu (TUM)
    23/11/2021, 15:20

    The Hubble constant (H0) is a key parameter in cosmology that sets the current expansion rate of the Universe. There is an intriguing tension between measurements of H0 from different methods. The tension could be due to errors in the measurements that are not yet accounted for. If this is ruled out, then new physics beyond the standard cosmological model would be needed to resolve the...

  24. 29. UV-Induced Photochemistry in Prebiotic Lakes
    Corinna Kufner (Harvard University)
    23/11/2021, 16:15

    On the surface of the early Earth and Earth-like exoplanets ultraviolet (UV) light acts as an important energy source. Particularly, UV light of different wavelength ranges can trigger a variety of photochemical reactions relevant to the molecular origins of life. However, the penetration depth of UV light into natural waters on early Earth and Earth-like exoplanets has remained an open...

    Christof Mast (LMU)
    23/11/2021, 16:45

    Absorption of UV photons by prebiotic chemicals is considered to be an important factor in driving important prebiotic reactions. In this seed project, we are evaluating the effect of UV radiation (260nm) on the sequence distribution of DNA and RNA oligomer pools. For this purpose, we have developed a high-throughput sequencing-based technique to simultaneously determine photodimer damage...

  26. 77. Seed Money 2021 : Initial Steps towards an Evolutionary System
    Oliver Trapp
    23/11/2021, 16:55

    All evolutionary biological processes lead to a change in heritable traits over successive generations. The responsible genetic information encoded in DNA is altered, selected, and inherited by mutation of the base sequence. While this is well known at the biological level, an evolutionary change at the molecular level of small organic molecules is unknown but represents an important...

  27. 32. Ferrocyanide survival under near ultraviolet (300-400 nm) irradiation on the early Earth
    Zoe Todd (U. of Washington, Seattle)
    23/11/2021, 17:05

    Prebiotic lake environments containing ferrocyanide could have fostered origins of life chemistry on the early Earth. Ferrocyanide, coupled with sulfite or sulfide, can participate in an ultraviolet (UV)-driven photoredox cycle to generate solvated electrons, which can reduce cyanide to form all four major building blocks of life: sugars, amino acids, nucleotides, and lipid precursors....

  29. 80. Data Science and the ODSL
    Lukas Heinrich (CERN/TUM)
    24/11/2021, 09:00

    A common thread of the ORIGINS is the presence of ever increasing data volumes both from instruments and simulation that simultaneously promise wealth of scientific insight. This data-intensive era, which often can only be managed in large scientific collaborations, coincides with a particularly interesting, but challenging phase in computing: While Machine Learning, particularly Deep...

  30. 72. Evaluating cosmic coincidences
    Francesca Capel (ODSL)
    24/11/2021, 09:30

    The multi-messenger era is now well-underway, with high-energy neutrinos providing a unique opportunity to study particle acceleration. Recent reports describe possible coincident detections of a single IceCube neutrino with a flaring blazar. While compelling, these sources cannot be considered in isolation. I will present various strategies to put these associations into the context of the...

  31. 75. Bayesian Reasoning with Trained Neural Networks
    Jakob Knollmüller (ORIGINS Data Science Lab)
    24/11/2021, 09:55

    In this talk we present how to combine independently trained neural networks to jointly solve novel tasks through Bayesian reasoning. Deep generative networks serve as prior distributions on complex systems and regression/classification networks are used to check whether certain features are present. Bayes Theorem allows us to then solve the inverse problem in terms of the latent variables of...

    Nahuel Ferreiro Iachellini (Origins)
    24/11/2021, 11:05

    The quest for dark matter has been puzzling scientists since over a century. The last two decades have seen no less than 20 experiments designed to directly detect dark matter in the local halo. Their sensitivities span over 5 orders of magnitude. In addition to those, hints for the presence of dark matter particles are sought-for in accelerators searches and in cosmic rays. These experiments...

  34. 14. C2PAP Highlight Talk : Monte Carlo challenges for Non Perturbative QED
    Anthony Hartin (LMU)
    24/11/2021, 11:30

    Non perturbative QED is used to predict beam backgrounds at the interaction point of colliders, in calculations of Schwinger pair creation and in precision QED tests with ultra-intense lasers.
    In order to predict these phenomena, custom built monte carlo event generators based on a suitable non perturbative theory have to be developed. One such suitable theory uses the Furry Interaction...

    Matthias Meier (MPP)
    24/11/2021, 14:00

    The possibilities to investigate astrophysical compact objects are strongly limited. Due to the small size of these objects it is hardly possible to resolve their geometry. The CubeSat mission ComPol will investigate the black hole binary system Cygnus X-1. The goal is to improve its physical model by measuring the polarization of the hard X-ray spectrum. The information about the polarization...

    Ligation and recombination of nucleic acids are key reactions required for both self-replication and the emergence of complex sequence information. It is therefore very likely that these reactions played a fundamental role in early stages of biology. We use different ribozyme systems as models to mimic how these reactions might have proceeded under heterogeneous reaction conditions on the...

    Henrique Rubira (TUM)
    25/11/2021, 15:20

    We study the effect of density perturbations on the process of first-order phase transitions and gravitational wave production in the early Universe. We are mainly interested in how the distribution of nucleated bubbles is affected by fluctuations in the local temperature. We find that large-scale density fluctuations ($H∗<k∗<\beta$) result in a larger effective bubble size at the time of...
