Importance of resolving the spectral support of beam-plasma instabilities in simulations
Mohamad Shalaby, Avery E. Broderick, Philip Chang +3
Many astrophysical plasmas are prone to beam-plasma instabilities. For relativistic and dilute beams, the {\it spectral} support of the beam-plasma instabilities is narrow, i.e., t…
Bow Ties in the Sky II: Searching for Gamma-ray Halos in the Fermi Sky Using Anisotropy
Paul Tiede, Avery E. Broderick, Mohamad Shalaby +4
Many-degree-scale gamma-ray halos are expected to surround extragalactic high-energy gamma ray sources. These arise from the inverse Compton emission of an intergalactic population…
Constraints on the Intergalactic Magnetic Field from Bow Ties in the Gamma-ray Sky
Paul Tiede, Avery E. Broderick, Mohamad Shalaby +4
Pair creation on the cosmic infrared background and subsequent inverse-Compton scattering on the CMB potentially reprocesses the TeV emission of blazars into faint GeV halos with s…
