The Signatures of Density Fluctuations and Mixing Gas in Circumgalactic Absorption Systems

The Astrophysical Journal
We investigate the prospects for detecting and constraining density and temperature inhomogeneities in the circumgalactic medium using absorption measurements of metal ions.

Modelling the cool gas clumps in the circumgalactic medium

Monthly Notices of the Royal Astronomical Society
ABSTRACT A major challenge in circumgalactic medium (CGM) studies is determining the three-dimensional (3D) properties from the observed projected observations. Here, we decompose the 3D gas density and spatial distribution of cool clouds by fitting a cool CGM model with the absorption observations, including the cool gas density, Ly ...

Transverse clues on the kiloparsec-scale structure of the circumgalactic medium as traced by C IV absorption [PDF]

The kiloparsec-scale kinematics and density structure of the circumgalactic medium (CGM) is still poorly constrained observationally, which poses a problem for understanding the role of the baryon cycle in galaxy evolution.

Azimuthal Anisotropy of Magnetic Fields in the Circumgalactic Medium Driven by Galactic Feedback Processes

, 2023
We use the TNG50 cosmological magnetohydrodynamical simulation of the IllustrisTNG project to show that magnetic fields in the circumgalactic medium (CGM) have significant angular structure.

Accretion-Driven Turbulence in the Circumgalactic Medium

Monthly Notices of the Royal Astronomical Society
Abstract Simulations suggest that turbulence is ubiquitous in the circumgalactic medium (CGM), though the source and properties of CGM turbulence is uncertain. Using analytic considerations and hydrodynamic simulations we study how CGM turbulence is driven by gas accretion, thus providing a baseline for additional turbulence driving ...
