A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories
Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2
We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…
The exceptional 2017 gamma-ray flare of the radio galaxy NGC 1275: VERITAS and Multiwavelength Observations
A. Acharyya, A. Archer, P. Bangale +66
The radio galaxy NGC 1275 is the Brightest Cluster Galaxy in the Perseus cluster. It is well-studied across all wavebands, including Very High Energy (VHE; E>100GeV gamma-rays, and…
PIC simulations of nonrelativistic high-Mach-number oblique shocks propagating in a turbulent medium
Karol Fulat, Eloise Moore, Mahmoud Alawashra +4
Collisionless shocks are common in astrophysical systems and stand as sites of particle acceleration. While particles at perpendicular shocks may not return to the upstream region,…
Investigation of the Microquasar SS 433 with VERITAS
The VERITAS Collaboration, A. Archer, P. Bangale +57
Microquasars such as SS 433 are considered potential contributors to cosmic rays up to the knee of the cosmic ray energy spectrum (), where a transition in the…
Cosmic rays: constraints from future MeV detectors
Giada Peron, Sarah Recchia, Stefano Menchiari +4
Cosmic rays are charged energetic particles that permeate the interstellar medium. Their sizeable energy share and penetration power makes them essential players in the dynamical a…
MeV cosmic-ray electrons modify the TeV pair-beam plasma instability
Mahmoud Alawashra, Yuanyuan Yang, Christopher M. Hirata +2
Relativistic pair beams created in the intergalactic medium (IGM) by TeV gamma rays from blazars are expected to produce a detectable GeV-scale electromagnetic cascade, but the cas…
