The COS-Halos Survey: An Empirical Description of the Metal-Line Absorption in the Low-Redshift Circumgalactic Medium
Jessica Werk, J. Xavier Prochaska, Christopher Thom +4
We present the equivalent width and column density measurements for low and intermediate ionization states of the circumgalactic medium (CGM) surrounding 44 low-z, L ~ L* galaxies…
Not Dead Yet: Cool Circumgalactic Gas in the Halos of Early Type Galaxies
Christopher Thom, Jason Tumlinson, Jessica K. Werk +10
We report new observations of circumgalactic gas in the halos of early type galaxies obtained by the COS-Halos Survey with the Cosmic Origins Spectrograph onboard the Hubble Space…
An empirical prediction for stellar metallicity distributions in nearby galaxies
Molly S. Peeples, Rachel S. Somerville
We combine star-formation histories derived from observations of high redshift galaxies with measurements of the z~0 relation between gas-phase metallicity, stellar mass, and star…
