The theory of resonant cosmic ray-driven instabilities -- Growth and saturation of single modes
Rouven Lemmerz, Mohamad Shalaby, Christoph Pfrommer +1
Cosmic ray (CR) feedback is critical for galaxy formation as CRs drive galactic winds, regularize star formation in galaxies, and escape from active galactic nuclei to heat the coo…
Coupling multi-fluid dynamics equipped with Landau closures to the particle-in-cell method
Rouven Lemmerz, Mohamad Shalaby, Timon Thomas +1
The particle-in-cell (PIC) method is successfully used to study magnetized plasmas. However, this requires large computational costs and limits simulations to short physical run-ti…
The Linear Instability of Dilute Ultrarelativistic Pair Beams
Philip Chang, Avery E. Broderick, Christoph Pfrommer +4
The annihilation of TeV photons from extragalactic TeV sources and the extragalactic background light produces ultrarelativistic beams, which are subject to powerful plas…
Bow Ties in the Sky I: The Angular Structure of Inverse Compton Gamma-ray Halos in the Fermi Sky
Avery E. Broderick, Paul Tiede, Mohamad Shalaby +4
Extended inverse Compton halos are generally anticipated around extragalactic sources of gamma rays with energies above 100 GeV. These result from inverse Compton scattered cosmic…
The Effect of Nonlinear Landau Damping on Ultrarelativistic Beam Plasma Instabilities
Philip Chang, Avery E. Broderick, Christoph Pfrommer +3
Very-high energy gamma-rays from extragalactic sources pair-produce off of the extragalactic background light, yielding an electron-positron pair beam. This pair beam is unstable t…
Dynamics and Light Propagation in a Universe with Discrete Matter Content
Mohamad Shalaby
We discuss a model for a universe with discrete matter content instead of the continuous perfect fluid taken in FRW models. We show how the redshift in such a universe deviates fro…
