Abstract
Absorption-selected galaxies associated with damped Ly-alpha absorbers (DLAs) provide a unique opportunity to study the gas in 'typical' galaxies at high redshifts. We have recently used ALMA to detect [CII] 158 micron or CO emission from ten DLAs at z 2-4, and the VLA to detect CO(2-1) emission from one of the z 4 DLAs. We propose to continue this successful ALMA+VLA project, complementing the ALMA observations with (1) a VLA search for CO(1-0) or CO(2-1) emission from five DLA hosts at z 2-4 with ALMA detections of CO or [CII] 158 micron emission, and (2) an HST-WFC3 imaging of 4 of the 5 DLA host galaxies with ALMA+VLA observations, covering the restframe near-UV continuum. The VLA observations will yield molecular gas masses for all five galaxies, and
