Radar based exploration of subglacial structures Ice-penetrating radar is one of the most important techniques in glaciological research. Applications can range from gaining insights about the internal structure of glaciers and ice sheets, to calculating ice volume, to the detection of hidden features such as crevasses. Recent advances in electronics...
New ECAP Lab information Stefan and Kay will report on the status, the usage strategy and the next steps for the ECAP Laboratory.
On the radiation signatures of Galactic PeVatrons: the gamma-ray and neutrino perspective Very-high-energy gamma rays and neutrinos are crucial messengers for assessing the PeVatron nature of cosmic sources. In particular, supernova remnants (SNRs) are since long time believed to be the major contributors to the Galactic cosmic-ray flux observed at...
Revealing Lightning with the LOFAR radio telescope Lightning is an extremely complex phenomena that is still only poorly understood. For example, we do not know how lightning initiates, how it propagates, or why it emits intense bursts of gamma radiation. One fundamental difficulty in studying lightning is that the best...
Multi-path tolerant beacon localization using a high antenna-count receiver In classic radar localization scenarios the transmitter and the receiver are in the same spot localizing a passive target by illuminating it with EM waves. However, more and more localization applications arise, where there is an active beacon/transmitter which is to...
Next-generation optical interferometry, or the return of Hanbury Brown and Twiss Hanbury Brown and Twiss are rightly famous as the pioneers of quantum optics in the 1950s, but their real goal was astronomical imaging to the sub-milliarcsecond scale and beyond, enough to resolve stars. This talk will explain how their...
The stellar content of the eROSITA all-sky survey The eROSITA instrument onboard the Russian-German SRG mission has so far completed more than four all-sky surveys and detected millions of new X-ray sources. Coronal X-ray sources, i.e. X-ray emitters similar to our Sun, constitute a significant fraction of the overall eROSITA...
Looking forward to exciting physics with FASER Physics searches and measurements at high-energy collider experiments traditionally focus on the high-pT region. However, if particles are light and weakly-coupled, this focus may be completely misguided: light particles are typically highly collimated around the beam line, allowing sensitive searches with small detectors,...
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...
