Multi-wavelength study of the galactic PeVatron candidate LHAASO J2108+5157

by Jakub Juryšek



The Cherenkov Telescope Array (CTA) Observatory will be the next generation ground-based very-high-energy gamma-ray observatory, sensitive from 20 GeV up to 300 TeV. The Large-Sized Telescope prototype (LST-1), currently in the commissioning phase, was inaugurated in October 2018 on La Palma (Spain). It is the first of four LST telescopes for CTA, to be built on La Palma. In 2021, LST-1 performed observations of one of the Galactic PeVatron candidates, LHAASO J2108+5157, recently discovered by the LHAASO collaboration. Two molecular clouds identified in the direction towards LHAASO J2108+5157 make the source a promising Galactic PeVatron candidate. I will present results of our analysis of the LST-1 data, putting strong constraints on the emission of the source in the multi-TeV band. I will also present results of multi-wavelength modeling of data from various instruments and discuss possible scenarios for the high energy emission of the source.


The seminar will be held in the conference hall in the main building of the Institute of Physics, Na Slovance 2, Prague 8 on the ground floor.
