Virial shocks are suppressed in cosmic ray-dominated galaxy halos

Suoqing Ji, Dušan Kereš, T. K. Chan +5

We study the impact of cosmic rays (CRs) on the structure of virial shocks, using a large suite of high-resolution cosmological FIRE-2 simulations accounting for CR injection by su…

Effects of Different Cosmic Ray Transport Models on Galaxy Formation

Philip F. Hopkins, T. K. Chan, Jonathan Squire +4

Cosmic rays (CRs) with ~GeV energies can contribute significantly to the energy and pressure budget in the interstellar, circumgalactic, and intergalactic medium (ISM, CGM, IGM). R…

Project AMIGA: The Circumgalactic Medium of Andromeda

Nicolas Lehner, Samantha C. Berek, J. Christopher Howk +22

Project AMIGA (Absorption Maps In the Gas of Andromeda) is a large ultraviolet Hubble Space Telescope program, which has assembled a sample of 43 QSOs that pierce the circumgalacti…

Testing Physical Models for Cosmic Ray Transport Coefficients on Galactic Scales: Self-Confinement and Extrinsic Turbulence at GeV Energies

Philip F. Hopkins, Jonathan Squire, T. K. Chan +4

The microphysics of ~GeV cosmic ray (CR) transport on galactic scales remain deeply uncertain, with almost all studies adopting simple prescriptions (e.g. constant-diffusivity). We…

Cosmic-Ray Driven Outflows to Mpc Scales from Galaxies

Philip F. Hopkins, T. K. Chan, Suoqing Ji +4

We study the effects of cosmic rays (CRs) on outflows from star-forming galaxies in the circum and inter-galactic medium (CGM/IGM), in high-resolution, fully-cosmological FIRE-2 si…
