In order to study the circumgalactic medium (CGM) of galaxies we develop an automated pipeline to estimate the optical continuum of quasars and detect intervening metal absorption line systemswith amatched kernel convolution technique and adaptive S/N criteria.We process ∼ one million quasars in the latest Data Release 16 (DR16) of the Sloan Digital Sky Survey (SDSS) and compile a large sample of ∼ 160,000 Mg ii absorbers, together with ∼ 70,000 Fe ii systems, in the redshift range 0.35 < zabs… 

Kinematics of Mg ii absorbers from the redshift-space distortion around massive quiescent galaxies

The kinematics of MgII absorbers is the key to understanding the origin of cool, metalenriched gas clouds in the circumgalactic medium of massive quiescent galaxies. Exploiting the fact that the

How are Lyα Absorbers in the Cosmic Web Related to Gas-rich Galaxies?

We present the correlation between Lyα absorbers and H i galaxies in the nearby universe (0.01 ≤ z ≤ 0.057). We find that Lyα absorbers are strongly correlated to H i galaxies at a projected

Quenched fractions in the IllustrisTNG simulations: comparison with observations and other theoretical models

We make an in-depth comparison of the IllustrisTNG cosmological simulations with observed quenched fractions of central and satellite galaxies, for Mstars = 109–12 M⊙ at 0 ≤ z ≤ 3. We show how

The Circumgalactic Medium of eBOSS Emission Line Galaxies: Signatures of Galactic Outflows in Gas Distribution and Kinematics

We study the distribution and kinematics of the cool circumgalactic medium (CGM) of emission line galaxies (ELGs) traced by metal absorption lines. Using about 200,000 ELGs from SDSS-IV eBOSS and

THE PROPERTIES OF THE COOL CIRCUMGALACTIC GAS PROBED WITH THE SDSS, WISE, AND GALEX SURVEYS

We explore the distribution of cool (∼104 K) gas around galaxies and its dependence on galaxy properties. By cross-correlating about 50,000 Mg ii absorbers with millions of sources from the SDSS

Constraining the Photometric Properties of Mg II-absorbing Galaxies with the Sloan Digital Sky Survey

Using a sample of nearly 700 quasars with strong [W0(2796) > 0.8 Å] Mg II absorption lines detected in the Early Data Release of the SDSS, we demonstrate the feasibility of measuring the photometric

MAGiiCAT IV. KINEMATICS OF THE CIRCUMGALACTIC MEDIUM AND EVIDENCE FOR QUIESCENT EVOLUTION AROUND RED GALAXIES

The equivalent widths of Mg II ?> absorption in the circumgalactic medium (CGM) trace the global star formation rate up to z < 6, are larger for star-forming galaxies than passively evolving

DUST IN THE CIRCUMGALACTIC MEDIUM OF LOW-REDSHIFT GALAXIES

Using spectroscopically selected galaxies from the Sloan Digital Sky Survey we present a detection of reddening effects from the circumgalactic medium of galaxies which we attribute to an extended

AN EMPIRICAL CHARACTERIZATION OF EXTENDED COOL GAS AROUND GALAXIES USING Mg ii ABSORPTION FEATURES

We report results from a survey of Mg ii absorbers in the spectra of background quasi-stellar objects (QSOs) that are within close angular distances to a foreground galaxy at z < 0.5, using the

We present new results on the kinematics and spatial distribution of metal-enriched gas within ∼125 kpc of star-forming (“Lyman break”) galaxies at redshifts 2 ≲ z ≲ 3. In particular, we focus on

We analyze the cross-correlation of Mg ii (λ2796,  2803) quasar absorption systems with luminous red galaxies (LRGs) from the Fifth Data Release (DR5) of the Sloan Digital Sky Survey. The absorption
