The two gamma-ray sources are TASG J1844-038—a newly detected source in this presented work—and HESS J1849-000. Reconstructing their gamma-ray energy spectra up to the sub-PeV range and also analyzing the archive data published by a radio survey, the book discusses in depth the emission mechanisms of the observed gamma rays and suggests that these two gamma-ray sources are candidates for PeVatrons. The results give insights into the population of PeVatron in the Galaxy, which is important to consider their contribution to the PeV cosmic rays observed at the Earth. 0aAstrophysics.968037 0aAstronomyxObservations.96797614aAstrophysics.96803724aAstronomy, Observations and Techniques.9679772 aSpringerLink (Online service)0 tSpringer Nature eBook08iPrinted edition:z978981971642508iPrinted edition:z978981971644908iPrinted edition:z9789819716456 0aSpringer Theses, Recognizing Outstanding Ph.D. Research,x2190-506196637040uhttps://doi.org/10.1007/978-981-97-1643-2  aZDB-2-PHA  aZDB-2-SXP  c59173d59173
