We use a particle tracking analysis to study the origins of the circumgalactic medium (CGM),
separating it into (1) accretion from the intergalactic medium (IGM),(2) wind from the central …

THE COS-HALOS SURVEY: ORIGINS OF THE HIGHLY IONIZED CIRCUMGALACTIC
MEDIUM OF STAR-FORMING GALAXIES - IOPscience This site uses cookies. By continuing to …

We report new observations of circumgalactic gas from the COS-Dwarfs survey, a systematic
investigation of the gaseous halos around 43 low-mass z⩽ 0.1 galaxies using background …

We use high-quality, medium-resolution Hubble Space Telescope/Cosmic Origins
Spectrograph (HST/COS) observations of 82 UV-bright active galactic nuclei (AGNs) at …

We summarize and reanalyze observations bearing on missing galactic baryons, where we
propose a consistent picture for halo gas in L≳ L* galaxies. The hot X-ray-emitting halos are …

We present a study of metal-enriched halo gas traced by Mg ii and C iv absorption at z< 2 in
the MUSE Analysis of Gas around Galaxies survey and the Quasar Sightline and Galaxy …

We present a study of extended galaxy halo gas through H i and O vi absorption over two
decades in projected distance at z≈ 0.2. The study is based on a sample of 95 galaxies …

We analyse the different fates of the circumgalactic medium (CGM) in FIRE-2 cosmological
simulations, focusing on the redshifts z= 0.25 and 2 representative of recent surveys. Our …

Context. The Milky Way is surrounded by large amounts of diffuse gaseous matter that
connects the stellar body of our Galaxy with its large-scale Local Group (LG) environment …

Galaxies and groups of galaxies exist in dark-matter haloes filled with diffuse gas. The
diffuse gas represents up to 80% of the mass in baryonic matter within the haloes,, but is …
