X-ray absorption lines in FUV-detected quasars: II. Cosmological density and properties of the missing baryons
Massimiliano Bonamente, David Spence, Jussi Ahoranta +3
This paper presents constraints on the cosmological density of baryons from a systematic search for O VII and O VIII absorption lines in the XMM-Newton and Chandra X-ray spectra of…

Cooling Flows as a Reference Solution for the Hot Circumgalactic Medium
Imran Sultan, Claude-André Faucher-Giguère, Jonathan Stern +3
The circumgalactic medium (CGM) in halos is dominated by a hot phase ( K). While many models exist for the hot gas structur…

X-ray absorption lines in FUV-detected quasars: I. Sample and analysis of the XMM-Newton and Chandra data
David Spence, Massimiliano Bonamente, Jussi Ahoranta +3
This paper presents initial results of a systematic search for resonance X-ray absorption lines from H-like O VIII and He-like O VII caused by the intervening warm-hot intergalacti…
