Thermal Structure and Chemical Enrichment of the North and South Polar Spurs: Supersolar N/O and Ne/O in the X-Ray Plasma

open access: yesThe Astrophysical Journal
The North Polar Spur (NPS) is a prominent diffuse X-ray feature whose origin has remained uncertain for decades. Using a uniform analysis of archival Suzaku and XMM-Newton data with new Chandra observations, we constrain its thermal and chemical ...

The impact of galactic feedback on the circumgalactic medium

open access: yes, 2019
Galactic feedback strongly affects the way galactic environments are enriched. We examine this connection by performing a suite of cosmological hydrodynamic simulations, exploring a range of parameters based on the galaxy formation model developed in ...

The Detection Rate of Associated Mg ii Absorption Lines in Quasars Depends on Their Radio Emission

open access: yesThe Astrophysical Journal
In active galactic nuclei, jet-driven feedback plays a significant role in influencing the properties of gas within their host galaxy and the circumgalactic medium.

Dust Survival in Galactic Winds

open access: yesThe Astrophysical Journal
We present a suite of high-resolution numerical simulations to study the evolution and survival of dust in hot galactic winds. We implement a novel dust framework in the Cholla hydrodynamics code and use wind tunnel simulations of cool, dusty clouds to ...

Spatially Resolved Circumgalactic Medium around a Star-forming Galaxy Driving a Galactic Outflow at z ≈ 0.8

open access: yesThe Astrophysical Journal
We report the small-scale spatial variation in cool ( T  ∼ 10 ^4 K) Mg ii absorption detected in the circumgalactic medium (CGM) of a star-forming galaxy at z  ≈ 0.8.

Quasars Probing Quasars: The Circumgalactic Medium Surrounding z ~ 2 Quasars [PDF]

open access: yes, 2017
Models of galaxy formation make the most direct predictions on gas related processes. Specifically, a picture on how gas flows through dark matter halos and onto galaxies to fuel star formation.

Deep Ultraviolet, Emission-line Imaging of the Makani Galactic Wind

open access: yesThe Astrophysical Journal
The O vi 1032, 1038 Å line is a key probe of cooling gas in the circumgalactic medium (CGM) of galaxies but has been observed to date primarily in absorption along single sight lines.

DIISC Survey: Deciphering the Interplay Between the Interstellar Medium, Stars, and the Circumgalactic Medium Survey

open access: yes
We present the Deciphering the Interplay between the Interstellar medium, Stars, and the Circumgalactic medium (DIISC) Survey. This survey is designed to investigate the correlations in properties between the circumgalactic medium (CGM), the interstellar
