We analyze intergalactic H i and O vi absorbers with v < 5000 km s−1 in Hubble Space Telescope and Far Ultraviolet Spectroscopic Explorer spectra of 76 active galactic nuclei. The baryons traced by H i/O vi absorption are clearly associated with the extended surroundings of galaxies; for impact parameters <400 kpc they are 2–4 times more numerous as those inside the galaxies. This large reservoir of matter likely plays a major role in galaxy evolution. We tabulate the fraction of absorbers… 

PROBING THE INTERGALACTIC MEDIUM/GALAXY CONNECTION. V. ON THE ORIGIN OF Lyα AND O vi ABSORPTION AT z < 0.2

We analyze the association of galaxies with Lyα and O vi absorption, the most commonly detected transitions of the low-z intergalactic medium (IGM), in the fields of 14 quasars with zem = 0.06–0.57.

An HST/COS legacy survey of intervening Si III absorption in the extended gaseous halos of low-redshift galaxies

Aims. Doubly ionized silicon (Si iii) is a powerful tracer of diffuse ionized gas inside and outside of galaxies. It can be observed in the local Universe in ultraviolet (UV) absorption against

THE SURPRISINGLY CONSTANT STRENGTH OF O vi ABSORBERS OVER COSMIC TIME

O vi absorption is observed in a wide range of astrophysical environments, including the local interstellar medium, the disk and halo of the Milky Way, high-velocity clouds, the Magellanic Clouds,

CGM2 I: The Extent of the Circumgalactic Medium Traced by Neutral Hydrogen

We present initial results from the Cosmic Origins Spectrograph (COS) and Gemini Mapping the Circumgalactic Medium (CGMCGM ≡ CGM2) survey. The CGM2 survey consists of 1689 galaxies, all with

We analyze the equivalent widths of H i ( ) absorption from the inner (R < 160 kpc) circumgalactic medium (CGM) of 85 galaxies at z ∼ 0 with stellar masses M* ranging . Across three orders of

The Relation between Galaxy ISM and Circumgalactic O vi Gas Kinematics Derived from Observations and ΛCDM Simulations

We present the first galaxy–O vi absorption kinematic study for 20 absorption systems (EW > 0.1 Å) associated with isolated galaxies (0.15 ≤ z ≤ 0.55) that have accurate redshifts and rotation curves

We present initial results from an ongoing large-scale study of the circumgalactic medium in the nearby Universe ( 10,000 ), using archival Cosmic Origins Spectrograph spectra of background

The relation between Lyα absorbers and local galaxy filaments

Context. The intergalactic medium (IGM) is believed to contain the majority of baryons in the universe and to trace the same dark matter structure as galaxies, forming filaments and sheets. Lyα

Evidence for a Rotational Component in the Circumgalactic Medium of Nearby Galaxies

We present results of a study comparing the relative velocity of Lyα absorbers to the rotation velocity of nearby galaxy disks in the local universe (z ≤ 0.03). We have obtained rotation curves via

THE HIGHLY IONIZED CIRCUMGALACTIC MEDIUM IS KINEMATICALLY UNIFORM AROUND GALAXIES

The circumgalactic medium (CGM) traced by O vi doublet absorption has been found to concentrate along the projected major and minor axes of the host galaxies. This suggests that O vi traces accreting
