Dark satellites as cosmological probes and gamma-ray dark matter targets A prediction of the standard LCDM cosmological model is that dark matter (DM) halos are teeming with numerous self-bound substructure, or subhalos. At small scales, subhalos may host no stars/gas at all and thus may not have visible astrophysical counterparts....

Quantum Gravity Searches with Neutrino Telescopes The Standard Model of particle physics and General Relativity are expected to merge into a new theory of Quantum Gravity (QG) at energies approaching the Planck scale. However, none of the proposed QG approaches has been validated to date. In this context, several signatures...

Observing Supernova Neutrinos with Hyper-Kamiokande and SNEWS 2.0 Hyper-Kamiokande is a next generation neutrino and nucleon decay experiment that is expected to start taking data in 2027. In this talk, I will introduce the experiment and discuss its neutrino astronomy programme, with a special focus on supernova neutrinos. Towards the...

Monitoring the High-Energy Sky with Small Satellites Thanks to the recent remarkable progress in the development of nano/micro/small-satellites and new launchers on the market, space is becoming increasingly more accessible. This provides new opportunities to diversify space astronomy which was hitherto dominated by relatively few large projects. I will describe...

News from NHR@FAU - Fritz, Alex and Woody The last year has seen quite a few changes in systems and setups at NHR@FAU. Georg Hager, Head of Training & Support, will present details about the flagship systems "Fritz" (Top500 rank 151) and "Alex" (Top500 rank 174) and how to get...

Resolving the Baryon Cycle within Nearby Galaxies The buildup of stellar mass through star formation is driven on small (<100pc) scales by physical processes and local conditions, but regulated across larger (kpc) scales through the baryon cycle. This entails the transformation of gas into stars, and eventual ejection and recycling...

MWL observations of GRBs Over the past five years, six long gamma-ray bursts (GRBs) have been found to have very high energy (VHE, >100 GeV) counterparts. As a result of this discovery, it has become apparent that we have been missing half of the energy produced in the afterglow of...

Ultrahigh energy cosmic rays: an origin story Understanding how ultrahigh energy cosmic rays (UHECRs) reach energies in excess of 1e20 eV stretches particle acceleration physics to its very limits. In this talk, I will discuss how such energies can be reached, using general arguments that can often be derived on...

Modeling and Observations of Cosmic Reionization In this talk I will introduce the topic of intergalactic medium reionization, its importance in the context of structure formation and how it is modeled from a theoretical point of view. I will then discuss how observations of the 21cm line from neutral hydrogen...

Low-cost high-fidelity data analysis with simulation-based inference The increasing volume and sophistication of astrophysical and cosmological data challenge traditional analysis methods, which often struggle with high-dimensional models and complex observations as seen for instance in gravitational waves, supernova cosmology, and gamma-ray data. Highlighting these limitations, this talk explores how deep...

Space Lasers and Aliens: Searching for optical transients with Gamma-ray Light Buckets Imaging atmospheric Cherenkov telescopes (IACTs) are among the largest and fastest optical telescopes in the world, ideally suited to searching for nanosecond-timescale optical transients. These could be astrophysical in nature, or even associated with signals transmitted by extra-terrestrial...

Search for primordial black hole dark matter with X-ray satellites and prospects for future missions Ultralight primordial black holes (PBHs) in the mass range of 1016 - 1022 g are allowed by current observations to constitute a significant fraction, if not all, of the dark matter in the Universe. In...
