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…
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…
Properties of the Circumgalactic Medium in Cosmic Ray-Dominated Galaxy Halos
Suoqing Ji, T. K. Chan, Cameron B. Hummels +6
We investigate the impact of cosmic rays (CRs) on the circumgalactic medium (CGM) in FIRE-2 simulations, for ultra-faint dwarf through Milky Way (MW)-mass halos hosting star-formin…
On the formation of density filaments in the turbulent interstellar medium
Siyao Xu, Suoqing Ji, A. Lazarian
This study is motivated by recent observations on ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The…
But What About... Cosmic Rays, Magnetic Fields, Conduction, & Viscosity in Galaxy Formation
Philip F. Hopkins, T. K. Chan, Shea Garrison-Kimmel +6
We present a suite of high-resolution cosmological simulations, using the FIRE-2 feedback physics together with explicit treatment of magnetic fields, anisotropic conduction and vi…
Simulations of radiative turbulent mixing layers
Suoqing Ji, S. Peng Oh, Phillip Masterson
Radiative turbulent mixing layers should be ubiquitous in multi-phase gas with shear flow. They are a potentially attractive explanation for the high ions such as OVI seen in high…
