The Gaseous Extent of Galaxies and the Origin of Lya Absorption Systems. V. Optical and Near-Infrared Photometry of Lya-absorbing Galaxies at z < 1

Abstract

(Abridged) We present results of a program to obtain and analyze HST WFPC2 images and ground-based images of galaxies identified in an imaging and spectroscopic survey of faint galaxies in fields of HST spectroscopic target QSOs. We confirm and improve the results presented by Lanzetta et al. (1995) and Chen et al. (1998) that (1) extended gaseous envelopes are a common and generic feature of galaxies of a wide range of luminosity and morphological type, (2) the extent of tenuous gas (N(H I) > 10^{14} cm^{-2} around galaxies scales with galaxy B-band luminosity as r\propto L_B^{0.39+/-0.09}, and (3) galaxy interactions do not play an important role in distributing tenuous gas around galaxies in most cases. We further demonstrate that (4) the gaseous extent of galaxies scales with galaxy K-band luminosity as r\propto L_K^{0.28+/-0.08}, and (5) tenuous gas around typical L_* galaxies is likely to be distributed in spherical halos of radius ~ 180 h^{-1} kpc of covering factor of nearly unity. Because galaxies of all morphological types possess extended gaseous halos and because the extent of tenuous gas around galaxies scales with galaxy K-band luminosity, we argue that galaxy mass---rather than recent star-formation activity---is likely to be the dominant factor that determines the extent of tenuous gas around galaxies. Nevertheless, applying the scaling relationship between the extent of Lya absorbing gas around galaxies and galaxy B-band luminosity, the results of our analysis also suggest that the number density evolution of Lya absorption systems may serve to constrain the evolution of the comoving galaxy B-band luminosity density (at least for the redshift interval between z~0 and z~1 that has been studied in our survey).
