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 explore different physically motivated, anisotropic, dynamical CR tr...

Cosmic-Ray Driven Outflows to Mpc Scales from L* Galaxies (2020)
Journal Article

We study the effects of cosmic rays (CRs) on outflows from star-forming galaxies in the circum and intergalactic medium (CGM/IGM), in high-resolution, fully cosmological FIRE-2 simulations (accounting for mechanical and radiative stellar feedback, ma...

A dark matter profile to model diverse feedback-induced core sizes of ΛCDM haloes (2020)
Journal Article
Lazar, A., Bullock, J. S., Boylan-Kolchin, M., Chan, T., Hopkins, P. F., Graus, A. S., …Garrison-Kimmel, S. (2020). A dark matter profile to model diverse feedback-induced core sizes of ΛCDM haloes. Monthly Notices of the Royal Astronomical Society, 497(2), 2393-2417. https://doi.org/10.1093/mnras/staa2101

We analyse the cold dark matter density profiles of 54 galaxy haloes simulated with Feedback In Realistic Environments (FIRE)-2 galaxy formation physics, each resolved within 0.5 per cent of the halo virial radius. These haloes contain galaxies with... Read More about A dark matter profile to model diverse feedback-induced core sizes of ΛCDM haloes.

The fates of the circumgalactic medium in the FIRE simulations (2020)
Journal Article
Murray, N., Chan, T., El-Badry, K., Wetzel, A., Esmerian, C., Kereš, D., …Hafen, Z. (2020). The fates of the circumgalactic medium in the FIRE simulations. Monthly Notices of the Royal Astronomical Society, 494(3), 3581-3595. https://doi.org/10.1093/mnras/staa902

We analyse the different fates of the circumgalactic medium (CGM) in FIRE-2 cosmological simulations, focusing on the redshifts z = 0.25 and 2 representative of recent surveys. Our analysis includes 21 zoom-in simulations covering the halo mass range... Read More about The fates of the circumgalactic medium in the FIRE simulations.
