SUMMARY:From Ultra-High Energy Cosmic Rays to the Study of Gamma Rays
DESCRIPTION:From Ultra-High Energy Cosmic Rays to the Study of Gamma Rays\n
 Mr. Patrick Cechvala\n\nFor the beginning of my presentation, I would like
  to briefly present the astronomy program at the Faculty of Mathematics, P
 hysics and Informatics of Comenius University in Bratislava, Slovakia.\nCo
 ntinuing, the main results of my diploma thesis will be presented during w
 hich I simulated the propagation of ultra-high energy cosmic rays throught
  the Universe using the simulation code SimProp v2r4 modelling the charact
 eristics of possible sources. The results were compared with the observati
 ons from the Pierre Auger Observatory which is situed in Argentina. Thesis
  has been made with the cooperation of the Institute of Physics of Czech A
 cademy of Sciences in Prague. Ultra-high energy cosmic rays (UHECRs) repre
 sent the subatomic particles, mainly protons and nuclei of different eleme
 nts, which can attain energies up to 1020 eV. Colliding with the Earth&acu
 te;s atmosphere they create the shower of secondary particles which can be
  detected by specific detectors on the ground. Origin of these particles w
 ith the highest energies is still a problem which haven´t been 
 solved to these days.\nBesides the corpuscular particles, the Earth is per
 manetly bombarded also by high energy photons or gamma rays. These are for
 med in the vicinity of exotic objects like active galactic nuclei (AGN) or
  supernova remnants (SNRs) or as a product of UHECRs. Colliding with 
 the atmosphere, they also create a shower of secondary particles whic
 h is narrower than in the case of UHECRs. To observe this shower the Imagi
 ng Atmospheric Cherenkov Telescopes (IACTs) have been developed observing 
 the Cherenkov light formed as a product of the cascade. Such telescop
 es are for example the MAGIC telescopes situed at Observatorio del Roque d
 e los Muchacos (ORM) on La Palma or the future Cherenkov Telescope Array (
 CTA) which northern part will be also situed at ORM.\nStudy of gamma rays 
 represents currently the main topic of my PhD project. For this reason I a
 m glad to had an opportunity to participate on ERASMUS+ mobility at IAC fo
 r 3 months and to cooperate with the astroparticle physics group. During t
 his period I have been analyzing archival data taken by MAGIC telescopes o
 f the active region around SNR G24.7+0.6. Specifically we are interested i
 n a source labeled as 2FHL J1839.5-0705. Preliminary results of my st
 udy will be presented.
