The Metallicity - Kinematics Relation in Large-N(HI) Absorbers
David A. Turnshek, Sandhya M. Rao, Daniel B. Nestor +2
Sloan Digital Sky Survey (SDSS) quasar spectroscopy is yielding a database of strong low-ionization MgII absorbers over the redshift interval 0.36<z<2.28 which is over two orders o…
Properties of Low-Redshift Damped Lyman Alpha Galaxies
Daniel B. Nestor, Sandhya M. Rao, David A. Turnshek +3
Images of five QSO fields containing six damped Lyman alpha (DLA) systems at redshifts 0.09<z<0.53 are presented. Identifications for the DLA galaxies giving rise to the DLA system…
A Comparative Study of Damped Lyman Alpha Galaxies
David A. Turnshek, Sandhya M. Rao, Daniel B. Nestor
We compare the properties of a sample of local (z=0) gas-rich galaxies studied in 21 cm emission to a sample of 13 low-redshift (z < 1) damped Lyman alpha (DLA) galaxies identified…
The Evolution of Neutral Gas in the Universe as Traced by Damped Lyman Alpha Systems
Sandhya M. Rao, David A. Turnshek
We discuss our recent results on the statistical properties of damped Lyman alpha systems (DLAs) at low redshift (z<1.65) (Rao & Turnshek 2000). Contrary to expectations, we found…
