Pressure-regulated, Feedback-modulated Star Formation in Disk Galaxies

EC Ostriker, CG Kim - The Astrophysical Journal, 2022 - iopscience.iop.org
The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

Cosmic-ray transport in varying galactic environments

L Armillotta, EC Ostriker, YF Jiang - The Astrophysical Journal, 2022 - iopscience.iop.org
We study the propagation of mildly relativistic cosmic rays (CRs) in multiphase interstellar
medium environments with conditions typical of nearby disk galaxies. We employ the …

The impact of cosmic rays on dynamical balance and disc–halo interaction in L⋆ disc galaxies

TK Chan, D Kereš, AB Gurvich… - Monthly Notices of …, 2022 - academic.oup.com
Cosmic rays (CRs) are an important component in the interstellar medium, but their effect on
the dynamics of the disc–halo interface (< 10 kpc from the disc) is still unclear. We study the …
