Detecting and Characterizing Mg ii Absorption in DESI Survey Validation Quasar Spectra

Detecting and Characterizing Mg ii Absorption in DESI Survey Validation Quasar Spectra

We present findings of the detection of Magnesium II (Mg ii , λ = 2796, 2803 Å) absorbers from the early data release of the Dark Energy Spectroscopic Instrument (DESI). DESI is projected to obtain spectroscopy of approximately 3 million quasars (QSOs), of which over 99% are anticipated to be at red...
