25. Features of Ultra-High Energy Cosmic Ray sources

5th-year student

The investigation of the mass composition relations to the large-scale anisotropies found in the arrival directions of ultra-high energy cosmic rays (UHECR).
Open framework simulator for simulated data generated by CRPropa3, which is a publicly available code to simulate the propagation of UHECR in the universe, for four primary particles, on which test for a directional anisotropy when...

10. Application of the deep machine learning for the studies of the muon air-shower component using the Pierre Auger Surface Detector data

5th-year student

The number of muons in air showers is one of the most important parameters linked to the mass of a primary particle. The knowledge of the mass composition is the key input required for verifying the astrophysical models describing the acceleration and propagation of cosmic rays. This talk will be devoted to the application of machine learning for the extraction of the muon component of the...

14. Longitudinal profiles of the highest energy cosmic-ray air showers measured at the Pierre Auger Observatory

5th-year student

Alternative reconstruction methods of the Pierre Auger Observatory data
measured by its fluorescence telescopes have the potential to extend the number
of detected cosmic-ray showers. This extension is of great importance especially
for ultra-high-energy showers burdened by very low statistic due to the steeply
decreasing flux of particles with their increasing energy. The increase of the...

5. Moon shadow (not) seen by the experiment KASCADE

4th-year student

The Moon blocks trajectories of cosmic rays, while the geomagnetic field of Earth deflects it, shifting it with the respect to the true Moon position. This offset can be wrongly interpreted as a systematic offset of event reconstruction, making the study of the Moon shadow crucial for correct event reconstruction. We investigate whether the Moon shadow is visible on the data recorded by the...

38. Evolution of galaxies in clusters

PhD student

The hot and dense environment of galaxy clusters represents a site of dramatic changes in member galaxies' morphology as they shift from blue gas-rich to red gas-poor objects due to multiple processes.
One of the essential external processes is the ram pressure stripping that galaxies experience while moving with high velocities through the hot intra-cluster medium (ICM), whose temperatures...

31. Southern Wide-field Gamma-ray Observatory (SWGO)

Alena Bakalová (CTU FNSPE)

PhD student

SWGO is a planned observatory of high energy gamma rays. It is going to be the first wide-field observatory in the Southern hemisphere and it will complement measurements from observatories in the Northern hemisphere like HAWC or LHAASO. The scientific potential of the experiment is extensive as it will provide access to transient and variable multi-wavelength and multi-messenger phenomena...
