Cosmic Ray Mediated Thermal Fronts in the Warm-hot Circumgalactic Medium

open access: yesThe Astrophysical Journal
We investigate the 1D plane-parallel front connecting the warm (10 ^4 K) and hot (10 ^6 K) phases of the circumgalactic medium (CGM), focusing on the influence of cosmic rays (CRs) in shaping these transition layers.

Zooming in on the Circumgalactic Medium with GIBLE: Resolving small-scale gas structure in cosmological simulations

open access: yesMonthly notices of the Royal Astronomical Society
We introduce Project GIBLE (Gas Is Better resoLved around galaxiEs), a suite of cosmological zoom-in simulations where gas in the circumgalactic medium (CGM) is preferentially simulated at ultra-high numerical resolution. Our initial sample consists of

Comparison of models for the warm-hot Circumgalactic Medium around Milky Way-like galaxies [PDF]

open access: yesMonthly notices of the Royal Astronomical Society
A systematic comparison of the models of the circumgalactic medium (CGM) and their observables is crucial to understanding the predictive power of the models and constraining physical processes that affect the thermodynamics of CGM. This paper compares

The Cosmic Ultraviolet Baryon Survey (CUBS). IX. The Enriched Circumgalactic and Intergalactic Medium Around Star-forming Field Dwarf Galaxies Traced by O vi Absorption

open access: yesThe Astrophysical Journal
The shallow potential wells of star-forming dwarf galaxies make their surrounding circumgalactic and intergalactic medium (CGM/IGM) sensitive laboratories for studying the inflows and outflows thought to regulate galaxy evolution.

The Hot Interstellar Medium in Normal Elliptical Galaxies III: The Thermal Structure of the Gas

open access: yes, 2008
This is the third paper in a series analyzing X-ray emission from the hot interstellar medium in a sample of 54 normal elliptical galaxies observed by Chandra, focusing on 36 galaxies with sufficient signal to compute radial temperature profiles.

Characterizing the Circumgalactic Medium of Nearby Galaxies with HST/COS and HST/STIS Absorption-Line Spectroscopy: II. Methods and Models

open access: yes, 2017
We present basic data and modeling for a survey of the cool, photo-ionized Circum-Galactic Medium (CGM) of low-redshift galaxies using far-UV QSO absorption line probes.

Resolving Turbulence Drivers in Two Luminous Obscured Quasars with JWST/NIRSpec Integral Field Unit

open access: yesThe Astrophysical Journal Letters
In this Letter, we investigate the turbulence and energy injection in the extended nebulae surrounding two luminous obscured quasars, WISEA J100211.29+013706.7 ( z = 1.5933) and SDSS J165202.64+172852.3 ( z = 2.9489).

Zooming in on the circumgalactic medium with GIBLE: The topology and draping of magnetic fields around cold clouds [PDF]

open access: yesAstronomy & Astrophysics
We used a cosmological zoom-in simulation of a Milky Way-like galaxy to study and quantify the topology of magnetic field lines around cold gas clouds in the circumgalactic medium (CGM).

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

open access: yesThe 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.
