Quasar Unsupervised Encoder and Synthesis Tool
Quasars at the redshift frontier (z>7.0) are fundamental probes of black hole growth and evolution but notoriously difficult to identify. At these redshifts, machine... -
BEINGMgII. III. Cool gas reservoirs
We investigate the origin of intervening cool MgII absorption detected in the spectra of background quasars and the nature of associated galaxies across a broad redshift range... -
