Constraining blazar heating with the 2<z<3 Lyman- forest
A. Lamberts, E. Puchwein, C. Pfrommer +5
The intergalactic medium (IGM) acts like a calorimeter recording energy injection by cosmic structure formation, shocks and photoheating from stars and active galactic nuclei. It w…
A new cosmic ray-driven instability
Mohamad Shalaby, Timon Thomas, Christoph Pfrommer
Cosmic ray (CR)-driven instabilities play a decisive role during particle acceleration at shocks and CR propagation in galaxies and galaxy clusters. These instabilities amplify mag…
The growth of the longitudinal beam-plasma instability in the presence of an inhomogeneous background
Mohamad Shalaby, Avery E. Broderick, Philip Chang +3
We study the longitudinal stability of beam-plasma systems in the presence of a density inhomogeneity in the background plasma. Previous works have focused on the non-relativistic…
Missing Gamma-ray Halos and the Need for New Physics in the Gamma-ray Sky
Avery E. Broderick, Paul Tiede, Philip Chang +5
An intergalactic magnetic field stronger than ~G would explain the lack of a bright, extended degree-scale, GeV-energy inverse Compton component in the gamma-ray s…
Growth of beam-plasma instabilities in the presence of background inhomogeneity
Mohamad Shalaby, Avery E. Broderick, Philip Chang +3
We explore how inhomogeneity in the background plasma number density alters the growth of electrostatic unstable wavemodes of beam plasma systems. This is particularly interesting…
