The Closest Damped Lyman Alpha System

  title={The Closest Damped Lyman Alpha System},

  journal={arXiv: Astrophysics},
A difficulty of studying damped Lyman alpha systems is that they are distant, so one knows little about the interstellar medium of the galaxy. Here we report upon a damped Lyman alpha system in the nearby galaxy NGC 4203, which is so close (v_helio = 1117 km/s) and bright (B_o = 11.62) that its HI disk has been mapped. The absorption lines are detected against Ton 1480, which lies only 1.9' (12 h_50 kpc) from the center of NGC 4203. Observations were obtained with the Faint Object Spectrograph… Expand

Reconciling the local galaxy population with damped Lyman α cross-sections and metal abundances
A comprehensive analysis of 355 high-quality Westerbork Synthesis Radio Telescope (WSRT) HI 21-cm line maps of nearby galaxies shows that the properties and incident rate of damped Lyman alphaExpand
Classical and Mg II-selected damped Lyman α absorbers: impact on ΩH I at z < 1.7
The Damped Lyman-alpha systems (DLAs), seen in absorption in the spectrum of quasars, are believed to contain a large fraction of the neutral gas in the Universe. Paradoxically, these systems areExpand
The Nature of Damped Lyα Absorbing Galaxies at z ≤ 1: A Photometric Redshift Survey of Damped Lyα Absorbers*
We study the nature of damped Lyα absorption (DLA) systems at z ≤ 1 using a sample of 11 DLA galaxies, for which accurate redshift measurements are available. Five of the 11 systems are identified inExpand
Calcium H & K Induced by Galaxy Halos
We present a measurement of the mean density profile of Ca II gas around galaxies out to ~200 kpc, traced by Fraunhofer's H & K absorption lines. The measurement is based on cross-correlating theExpand
The neutral gas extent of galaxies as derived from weak intervening CaII absorbers

Evolutionary paths to and from the red sequence: star formation and H i properties of transition galaxies at z∼ 0
We investigate the properties of galaxies between the blue and the red sequence (i.e. the transition region, 4.5 < NUV - H < 6 mag) by combining ultraviolet (UV) and near-infrared imaging to 21-cm HExpand
Star formation in the outer regions of the early-type galaxy NGC 4203
NGC 4203 is a nearby early-type galaxy surrounded by a very large, low-column-density HI disc. In this paper, we study the star formation efficiency in the gas disc of NGC 4203 by using the UV, deepExpand
The column density distribution function at z = 0 from H i selected galaxies
