Implication

This investigation uncovers the nature of cool gas reservoirs in galaxies, highlighting their association with star formation rates and stellar masses.

Key Points

The aim is to investigate the origins and associations of cool absorption in quasar spectra within certain redshift ranges.
Analyzed spectra of background quasars using DESI fiber optics.
Detected galaxies based on nebular emission lines at redshifts from 0.3 to 1.6.
Measured absorber strengths and equivalent widths to determine relationships with galaxy properties.
Detected a significant fraction of galaxies associated with strong absorbers across the specified redshifts.
Found that absorber strength increased with redshift, indicating more cool gas in galaxy halos over time.
Identified a positive correlation between absorber strength, stellar mass, and star formation rates.
