An HST/COS Survey of the Low-Redshift IGM. I. Survey, Methodology, & Overall Results

Charles W. Danforth, Brian A. Keeney, Evan M. Tilton +12

We use high-quality, medium-resolution {\it Hubble Space Telescope}/Cosmic Origins Spectrograph (\HST/COS) observations of 82 UV-bright AGN at redshifts to construct…

An HST/COS Search for Warm-Hot Baryons in the Mrk421 Sightline

Charles W. Danforth, John T. Stocke, Brian A. Keeney +4

Thermally-broadened Lya absorbers (BLAs) offer an alternate method to using highly-ionized metal absorbers (OVI, OVII, etc.) to probe the warm-hot intergalactic medium (WHIM, T=10^…

Diffuse Far-UV Line Emission from the Low-Redshift Lyman Break Galaxy Analog KISSR242

Kevin France, Nicholas Nell, James C. Green +1

We present new ultraviolet (UV) observations of the luminous compact blue galaxy KISSR242, obtained with the HST-COS. We identify multiple resolved sub-arcsecond near-UV sources wi…

Cosmic Origins Spectrograph Detection of Ne VIII Tracing Warm - Hot Gas Towards PKS 0405-123

Anand Narayanan, Blair D. Savage, Bart P. Wakker +7

We report on the detection of Ne VIII in the HST/Cosmic Origins Spectrograph spectrum of the intervening absorption system at z = 0.495096 towards PKS 0405-123. The high S/N COS sp…

Cosmic Origins Spectrograph Observations of the Chemical Composition of LMC N132D

Kevin France, Matthew Beasley, Brian A. Keeney +3

We present new far-ultraviolet spectra of an oxygen-rich knot in the Large Magellanic Cloud supernova remnant N132D, obtained with the Hubble Space Telescope/Cosmic Origins Spectro…
