Galactic Sources of VHE Gamma-Ray Emission - Highlights from VERITAS

Explore cutting-edge research in very high-energy gamma-ray astronomy through this comprehensive lecture by Professor Reshmi Mukherjee from Barnard College, Columbia University. Delve into the groundbreaking observations made by the VERITAS observatory in southern Arizona, examining how its four atmospheric Cherenkov telescopes detect gamma rays above 100 GeV from various galactic sources. Learn about shell-type supernova remnants, pulsar wind nebulae, gamma-ray binary systems, and PeVatrons - powerful cosmic accelerators potentially responsible for cosmic rays up to the knee of the spectrum. Discover how VERITAS's high-resolution observations contribute to identifying PeVatron candidates and understanding particle acceleration mechanisms, particularly in light of recent discoveries by HAWC and LHAASO of sources emitting above 100 TeV. Gain insights into ongoing collaborative efforts between the VHE Astrophysics Group at Columbia University and ICCUB, exploring the nature of these fascinating astrophysical accelerators and their role in cosmic-ray production.
