A Deep Search For Faint Galaxies Associated With Very Low-redshift C IV Absorbers: III. The Mass- and Environment-dependent Circumgalactic Medium
Joseph N. Burchett, Todd M. Tripp, Rongmon Bordoloi +6
Using Hubble Space Telescope Cosmic Origins Spectrograph observations of 89 QSO sightlines through the Sloan Digital Sky Survey footprint, we study the relationships between C IV a…
On the OVI Abundance in the Circumgalactic Medium of Low-Redshift Galaxies
Joshua Suresh, Kate H. R. Rubin, Rahul Kannan +3
We analyze the mass, temperature, metal enrichment, and OVI abundance of the circumgalactic medium (CGM) around galaxies of mass $10^9 M_\odot <M_\bigstar < 10^{11.5} M…
A Deep Search For Faint Galaxies Associated With Very Low-redshift C IV Absorbers: II. Program Design, Absorption-line Measurements, and Absorber Statistics
Joseph N. Burchett, Todd M. Tripp, J. Xavier Prochaska +6
To investigate the evolution of metal-enriched gas over recent cosmic epochs as well as to characterize the diffuse, ionized, metal-enriched circumgalactic medium (CGM), we have co…
Towards the statistical detection of the warm-hot intergalactic medium in inter-cluster filaments of the cosmic web
Nicolas Tejos, J. Xavier Prochaska, Neil H. M. Crighton +6
Modern analyses of structure formation predict a universe tangled in a 'cosmic web' of dark matter and diffuse baryons. These theories further predict that at low-z, a significant…
Baryon Cycling in the Low-Redshift Circumgalactic Medium: A Comparison of Simulations to the COS-Halos Survey
Amanda Brady Ford, Jessica K. Werk, Romeel Dave +8
We analyze the low-redshift (z~0.2) circumgalactic medium by comparing absorption-line data from the COS-Halos Survey to absorption around a matched galaxy sample from two cosmolog…
