Absorption line abundances in the SMC-like galaxy UGC 5282: evidence for ISM dilution from inflows on kiloparsec scales

Autor: Todd M. Tripp, Renyue Cen, Edward B. Jenkins, Donald G. York, David V. Bowen, Max Pettini, D. Chelouche

We present an HST Cosmic Origins Spectrograph (COS) spectrum of the QSO SDSS J095109.12+330745.8 ($z_{em} = 0.645$) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ($M_B = -16.0$, $cz = 1577$ km s$^{-1}$ ), 1.2 kpc in projection fro

A Sub-Damped Ly$\alpha$ Absorber with Unusual Abundances: Evidence of Gas Recycling in a Low-Redshift Galaxy Group

Autor: Sara L. Ellison, Brenda Frye, Todd M. Tripp, David V. Bowen, Max Pettini, Edward B. Jenkins

Using Hubble Space Telescope/Space Telescope Imaging Spectrograph G140M spectroscopy, we investigate an absorption-line system at $z$=0.07489 in the spectrum of the quasi-stellar object PG 1543+489 ($z_{QSO}$=0.401). The sightline passes within $\rho

Autor: Nicolas Lehner, J. Christopher Howk, John M. O'Meara, Christopher B. Wotta, Molly S. Peeples, David V. Bowen, Michelle A. Berg, Nicolas Tejos, Joseph N. Burchett

We present a search for HI in the circumgalactic medium (CGM) of 21 massive ($\langle \log M_\star \rangle \sim 11.4$), luminous red galaxies (LRGs) at $z\sim0.5$. Using UV spectroscopy of QSO sightlines projected within 500 kpc ($\sim R_{vir}$) of t

We survey the highly ionized circumgalactic media (CGM) of 29 blindly selected galaxies at 0.49 < z_(gal) < 1.44 based on high-S/N ultraviolet spectra of z > 1 QSOs and the galaxy database from the COS Absorption Survey of Baryon Harbors (CASBaH). We

Warm-hot Gas in X-ray Bright Galaxy Clusters and the H I-deficient Circumgalactic Medium in Dense Environments

Autor: Edward B. Jenkins, Todd M. Tripp, David V. Bowen, Joseph N. Burchett, Q. Daniel Wang, Christopher N. A. Willmer

We analyze the intracluster medium (ICM) and circumgalactic medium (CGM) in 7 X-ray detected galaxy clusters using spectra of background QSOs (HST-COS/STIS), optical spectroscopy of the cluster galaxies (MMT/Hectospec and SDSS), and X-ray imaging/spe

Galaxies with background QSOs – II. An automated search for multiple galaxy emission lines

Autor: Zakary L. Whichard, Varsha P. Kulkarni, Lorrie A. Straka, Donald G. York, Pushpa Khare, Michael Bishof, David V. Bowen

Publikováno v: Monthly Notices of the Royal Astronomical Society. 436:3200-3223

We have improved upon our previous search technique of systematically searching QSO spectra for narrow galactic H-alpha emission, which indicates a foreground galaxy within the Sloan Digital Sky Survey (SDSS) spectral fiber. We now search for H-alpha
