Signal reconstruction for fields using probabilistic forward modeling Many inference tasks in observational astronomy take the form of reconstruction problems where the underlying quantities of interest are fields (functions of space, time and/or frequency) that have to be recovered from noisy and incomplete observational data. These problems are in general...
Rotation-powered pulsars and their nebulae – the eROSITA view SRG/eROSITA is a soft X-ray (0.2 - 10 keV) telescope which has carried out the deepest X-ray all-sky survey to date. In this talk, I will present how the eROSITA data can be used to study rotation-powered pulsars and their pulsar...
Intricacies of searching for supernova remnants at (very) high energies off the Galactic plane Supernova remnants (SNRs) have traditionally been considered prime candidates for the acceleration of particles to high energies and to thus significantly contribute to the Galactic cosmic ray (CR) density. Most of them are first seen at...

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...
