TL;DR: The Cosmic Origins Spectrograph (COS) as discussed by the authors is a moderate-resolution spectrograph with unprecedented sensitivity that was installed into the Hubble Space Telescope (HST) in May 2009, during HST Servicing Mission 4 (STS-125).
Journal ArticleDOI
The Baryon Census in a Multiphase Intergalactic Medium: 30% of the Baryons May Still Be Missing
TL;DR: In this paper, the baryon census in the (H I) Ly{alpha} forest and warm-hot IGM (WHIM) at 10{sup 5-6} K traced by O VI {lambda}1032, 1038 absorption was updated.

Characterizing the circumgalactic medium of nearby galaxies with hst/cos and hst/stis absorption-line spectroscopy*
John T. Stocke,Brian A. Keeney,Charles W. Danforth,J. Michael Shull,Cynthia S. Froning,James C. Green,Steven V. Penton,Blair D. Savage +7 more
TL;DR: In this article, the circumgalactic medium (CGM) of late-type galaxies is characterized using UV spectroscopy of 11 targeted QSO/galaxy pairs at z ≤ 0.02 with the Hubble Space Telescope Cosmic Origins Spectrograph (COS) and ~60 serendipitous absorber/gazetteer pairs at 0.2 with the Space Telescope imaging spectrograph, and the authors derived the CGM warm cloud properties, including volume filling factors of 3-5, cloud sizes of 0.1-30 kpc, masses of

The Low-z Intergalactic Medium. III. H I and Metal Absorbers at z < 0.4
TL;DR: In this article, an ultraviolet (HST and FUSE) spectroscopic survey of H I (Lyman lines) and seven metal ions (O VI, N V, C IV, C III, Si IV, Si III, Fe III) in the low-redshift IGM at z < 0.4 was conducted.
