Spectroscopic confirmation of an ultramassive and compact galaxy at Z = 3.35: A detailed look at an early progenitor of local giant ellipticals

Spectroscopic confirmation of an ultramassive and compact galaxy at Z = 3.35: A detailed look at an early progenitor of local giant ellipticals

We present the first spectroscopic confirmation of an ultramassive galaxy at redshift z > 3 using data from Keck- NIRSPEC, VLT-X-shooter, and GTC-Osiris. We detect strong [O III] and Lya emission, and weak [O II], C IV, and He II, placing C1-23152 at a spectroscopic redshift of zspec = 3.351....
