The COS-Halos Survey: Physical Conditions and Baryonic Mass in the Low-Redshift Circumgalactic Medium
Jessica K. Werk, J. Xavier Prochaska, Jason Tumlinson +13
We analyze the physical conditions of the cool, photoionized (T K) circumgalactic medium (CGM) using the COS-Halos suite of gas column density measurements for 44 gaseo…
The High-Ion Content and Kinematics of Low-Redshift Lyman Limit Systems
Andrew J. Fox, Nicolas Lehner, Jason Tumlinson +9
We study the high-ionization phase and kinematics of the circumgalactic medium around low-redshift galaxies using a sample of 23 Lyman Limit Systems (LLSs) at 0.08<z<0.93 observed…
The COS-Halos Survey: Rationale, Design, and A Census of Circumgalactic Neutral Hydrogen
Jason Tumlinson, Christopher Thom, Jessica Werk +11
We present the design and methods of the COS-Halos survey, a systematic investigation of the gaseous halos of 44 z = 0.15-0.35 galaxies using background QSOs observed with the Cosm…
A fundamental problem in our understanding of low mass galaxy evolution
Simone M. Weinmann, Anna Pasquali, Benjamin D. Oppenheimer +4
Recent studies have found a dramatic difference between the observed number density evolution of low mass galaxies and that predicted by semi-analytic models. While models accurate…
