Two years of eROSITA all-sky surveys: The variable X-ray sky The eROSITA telescope onboard the SRG satellite was launched on 13 July 2019. After an initial phase of calibration and performance verification observations eROSITA started its all-sky survey operation in December 2019. Covering the entire sky within 6 months, eROSITA...

Galaxy evolution and cosmology using gamma rays observed with Fermi-LAT The light emitted by all galaxies across the history of the Universe is encoded in the intensity of the extragalactic background light (EBL), the diffuse cosmic radiation field at ultraviolet, optical, and infrared wavelengths. The EBL is a source of...

The Muon Puzzle in cosmic-ray induced air showers and its connection to the LHC High-energy cosmic rays are observed indirectly by detecting extensive particle showers initiated in Earth's atmosphere. These so-called air showers are hadronic cascades which produce a muon component via hadron decay. The muon number is a key...

Recent highlights from the LHAASO observatory The Large High Altitude Air Shower Observatory (LHAASO), located in China at 4410m above sea level, is a complex of extensive air shower (EAS) detector array. Utilizing different detection techniques, LHAASO surveys the entire northern gamma-ray and cosmic-ray sky with a wide energy range...

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...

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...

Long Night of Sciences 2022

Hörsaalgebäude Physikum Staudtstr. 5, Erlangen, Germany

During the Long Night of Sciences in 2022 the Erlangen Centre for Astroparticle Physics will once again be part of the program. Scientists from different ECAP groups will present their work in an exhibition with posters and many exhibition items: A cloud chamber, a scale model of a modern gamma-ray...

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...
