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…
A high molecular fraction in a sub-damped absorber at z=0.56
Neil H. M. Crighton, Jill Bechtold, Robert F. Carswell +8
Measuring rest-frame ultraviolet rotational transitions from the Lyman and Werner bands in absorption against a bright background continuum is one of the few ways to directly measu…
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…
On the redshift of the blazar PKS0447-439
Michele Fumagalli, Amy Furniss, John M. O'Meara +3
PKS0447-439 is one of the BL Lacertae objects that have been detected at very high energy. There has been a recent report of a lower limit of z>1.246 for the redshift of this blaza…
The HST/ACS+WFC3 Survey for Lyman Limit Systems II: Science
John M. O'Meara, J. Xavier Prochaska, Gabor Worseck +2
We present the first science results from our Hubble Space Telescope Survey for Lyman limit absorption systems (LLS) using the low dispersion spectroscopic modes of the Advanced Ca…
Precious Metals in SDSS Quasar Spectra I: Tracking the Evolution of Strong, 1.5 < z < 4.5 CIV Absorbers with Thousands of Systems
Kathy L. Cooksey, Melodie M. Kao, Robert A. Simcoe +2
We have vastly increased the CIV statistics at intermediate redshift by surveying the thousands of quasars in the Sloan Digital Sky Survey Data-Release 7. We visually verified over…
