Stellar Mass–Dispersion Measure Correlations Constrain Baryonic Feedback in Fast Radio Burst Host Galaxies

The Astrophysical Journal Letters
Low-redshift fast radio bursts (FRBs) enable robust measurements of the host galaxy contribution to the dispersion measure (DM), offering valuable constraints on the circumgalactic medium (CGM) of FRB hosts.

On the Origin of the 107 K Hot Emitting Gas in the Circumgalactic Medium of the Milky Way

The Astrophysical Journal
The presence of the ≈10 ^6 K gas in the circumgalactic medium of the Milky Way (MW) has been well established. However, the location and the origin of the newly discovered hot gas at “supervirial (SV)” temperatures of ≈10 ^7 K have been puzzling.

Dual-disk galaxies and thermal states of circumgalactic medium

The Open Journal of Astrophysics
Disk galaxies often have dual-disk structures composed of thin disks and thick disks. Recent observations reveal that such duality is ubiquitous across broad galaxy mass and cosmic time.

Dynamics of Multiphase Carbon in the Turbulent Circumgalactic Medium

The Astrophysical Journal
The circumgalactic medium (CGM) plays a crucial role in regulating material and energy exchange between galaxies and their environments. The best means of observing this medium is through absorption-line spectroscopy, but we have yet to develop a ...

The Dispersion Measure and Scattering of Fast Radio Bursts: Contributions from Multicomponents, and Clues for the Intrinsic Properties

The Astrophysical Journal Supplement Series
Fast radio bursts (FRBs) are luminous, millisecond-duration transients that offer great potential for probing the Universe, yet their physical origins remain unclear.

X-ray signatures of galactic outflows into the circumgalactic medium

We present a set of controlled hydrodynamical simulations to study the effects of strong galactic outflows on the density and temperature structures, and associated X-ray signatures, of extra-planar and circumgalactic gas. We consider three initial state
