RUBIES Reveals a Massive Quiescent Galaxy at z = 7.3

We report the spectroscopic discovery of a massive quiescent galaxy at z _spec  = 7.29 ± 0.01, just  ∼700 Myr after the big bang. RUBIES-UDS-QG-z7 was selected from public JWST/NIRCam and MIRI imaging from the PRIMER survey and observed with JWST/NIRSpec as part of RUBIES. The NIRSpec/PRISM spectrum...
