PublicationSpectroscopic Confirmation of an Ultra Massive and Compact Galaxy At Z = 3.35: a Detailed Look At an Early Progenitor of Local Giant EllipticalsWe present the first spectroscopic confirmation of an ultramassive galaxy at redshift z\gt 3 using data from Keck-NIRSPEC, VLT-X-shooter, and GTC-Osiris. We...
