The Circumgalactic Medium with Local Universe Fast Radio Bursts: Evidence of Strong Active Galactic Nucleus Feedback in a Massive Elliptical Galaxy

The Astrophysical Journal Letters
Modern cosmology and galaxy formation rely on an understanding of how cosmic baryons are distributed, a significant portion of which exists in the diffuse gas confined to halos. Fast radio bursts (FRBs) are a promising probe of the Universe’s ionized gas.

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.

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.

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 MUSECuBES surveys on the circumgalactic medium

, 2019
The circumgalactic medium (CGM) is a dynamic, complex, multiphase, metal-enriched gas reservoir surrounding galaxies which harbors gas and metal masses comparable to those in galaxies themselves. Using a large quantity of spectral and imaging data obtained with MUSE & UVES on the VLT and ACS & COS on-board HST, we have started a major campaign ...

Tracing the Cosmic Evolution of the Cool Circumgalactic Medium of Luminous Red Galaxies with DESI Year 1 Data

The Astrophysical Journal
We investigate the properties of the cool circumgalactic medium (CGM) of massive galaxies and their cosmic evolution. By using the year 1 data set of luminous red galaxies (LRGs) and QSOs from the Dark Energy Spectroscopic Instrument survey, we construct

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 ...
