The Cosmic Evolution and Spatial Distribution of Multiphase Gas Associated with QSOs
We investigate the multiphase gas surrounding QSOs traced by 33 absorption lines (e.g., Ly α , C iv , Fe ii , Mg ii , etc.) in the stacked spectra of background sources, using the Early Data Release from the Dark Energy Spectroscopic Instrument. Our analysis reveals that the equivalent width ( W ) o...
