Black hole evaporation and quantum gravity Hawking's seminal result, that black holes behave as black bodies with a non-vanishing temperature, suggests that black holes should evaporate. However, Hawking's derivation is incomplete as it neglects the backreaction between radiation and geometry. Including it requires to incorporate quantum gravity. This talk focuses...

Satellite Constellations & Astronomy: What is the problem? What are we doing about it? In recent years, large satellite constellations have been launched into low-Earth orbit to provide low-latency, global communication coverage. As a result, the number of satellites in orbit has surged from approximately 2,500 to over 10,000, raising...

Optical spectroscopy and imaging of blazars for the Cherenkov Telescope Array Observatory Blazars are the brightest persistent sources in the high-energy and very-high-energy (VHE) gamma-ray sky. Because their UV/optical radiation is often dominated by non-thermal, and, in the case of BL Lacs, featureless continuum radiation, the determination of their redshift...

Finding evidence for self-enrichment and supermassive stars in forming globular clusters Self-enrichment is one of the leading explanations for chemical anomalies in globular clusters. In this scenario, a polluter star enriches a forming cluster with its yields, likely ejecting radioactive 26Al into its surroundings. Young massive star clusters, as potential...

From Research to Practice: Applying Artificial Intelligence in the Insurance Industry This presentation provides insights into the practical applications of artificial intelligence (AI) and machine learning in the insurance sector. Using examples from our work at ControlExpert, I will demonstrate how advanced image recognition and natural language processing (NLP) technologies...

Dark Matter Searches with VERITAS and Dark100 Indirect dark matter searches are an important piece of the search for dark matter. One indirect search method is to use very-high-energy (E > 100 GeV) gamma rays as a probe of dark matter annihilation or decay in dark-matter-rich astrophysical systems. Gamma rays...

Ultra-high energy cosmic rays: Constraints on the maximum-energy distribution of the sources and the possible role of ultra-fast outflows in active galactic nuclei An open question in the search for ultra-high-energy cosmic-ray (UHECR) sources is whether they are few and prominent or if a large population of sources collectively contributes...

Likelihood-free inference and gamma-ray astronomy Estimating (physical) model parameters θ from experimental data x is one of the core tasks in any field of physics. Statistical estimation procedures frequently make use of the likelihood function p(x|θ). Often, the likelihood can not be evaluated explicitly, but can be efficiently sampled from....

Forcing neutrinos to obey the holographic principle Gravity does not like the vast amounts of states present in QFT, and quantum gravitational effects are expected to drastically reduce the dimension of the QFT Hilbert space. This is e.g. achieved by "operator dressing", which changes the commutation relations of quantum fields....
