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…

Virialization of the inner CGM in the FIRE simulations and implications for galaxy discs, star formation and feedback

Jonathan Stern, Claude-André Faucher-Giguère, Drummond Fielding +13

We use the FIRE-2 cosmological simulations to study the formation of a quasi-static, virial-temperature gas phase in the circumgalactic medium (CGM) at redshifts 0<z<5, and how the…

Pressure balance in the multiphase ISM of cosmologically simulated disk galaxies

Alexander B. Gurvich, Claude-André Faucher-Giguère, Alexander J. Richings +13

Pressure balance plays a central role in models of the interstellar medium (ISM), but whether and how pressure balance is realized in a realistic multiphase ISM is not yet well und…

A dark matter profile to model diverse feedback-induced core sizes of CDM haloes

Alexandres Lazar, James S. Bullock, Michael Boylan-Kolchin +11

We analyze the cold dark matter density profiles of 54 galaxy halos simulated with FIRE-2 galaxy formation physics, each resolved within of the halo virial radius. These ha…

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…

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…
