Presentation #118.06 in the session Large Surveys, Programs and Catalogs.
PeVatrons are astrophysical sources capable of accelerating cosmic rays up to PeV energies. These sources also create gamma rays having energies greater than 100 TeV. LHAASO J2108+5157 is a PeVatron candidate first detected by Large High Altitude Air Shower Observatory (LHAASO). Since it’s first detection, the region has been analyzed by both LHAASO and the first Large-Sized Telescope (LST-1), but the origin of the ultra high energy (>100 TeV) gamma rays still remains unknown. In its newly reconstructed dataset, the High Altitude Water Cherenkov (HAWC) observatory has significantly detected this source above 6 TeV. There is an ongoing joint analysis using data from both the HAWC observatory and Very Energetic Radiation Imaging Telescope Array System (VERITAS). I will present the results of the analysis of HAWC data in the J2108+5157 region, as well as the multiwavelength modeling which includes both HAWC and VERITAS data.
