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…

Radio polarization from runaway star bowshocks-I. The general case
M. V. del Valle, R Santos-Lima, M Pohl
High velocity stars move through the interstellar medium with V > 30 km/s. When the star has powerful winds, under the appropriate conditions, the interaction of the wind with the…

An in-depth study of Gamma rays from the Starburst Galaxy M 82 with VERITAS
Atreya Acharyya, Colin B. Adams, Priyadarshini Bangale +60
Assuming Galactic cosmic rays originate in supernovae and the winds of massive stars, starburst galaxies should produce very-high-energy (VHE; E100 GeV) gamma-ray emission via t…
