Description
Damped Lya absorbers (DLAs) probe the neutral gas in the interstellar medium, extended rotating disks, and likely dense gaseous streams in galaxy halos. The large gas surface mass densities revealed in DLAs are comparable to what is seen in 21 cm observations of nearby star-forming galaxies, making DLAs a promising signpost of distant young galaxies. In this talk, I will present new damped Lya absorbers discovered in the Cosmic Ultraviolet Baryon Survey (CUBS), along with new observations that cast new insights into the physical origin of the gas.
