MAGAZ3NE: Massive, Extremely Dusty Galaxies at z∼ 2 Lead to Photometric Overestimation of Number Densities of the Most Massive Galaxies at 3< z< 4
The Astrophysical Journal, 2024•iopscience.iop.org
We present rest-frame optical spectra from Keck/MOSFIRE and Keck/NIRES of 16 candidate
ultramassive galaxies targeted as part of the Massive Ancient Galaxies at z> 3 Near-Infrared
Survey (MAGAZ3NE). These candidates were selected to have photometric redshifts 3≲ z
phot< 4, photometric stellar masses ${\rm {log}}({M} _ {\ast}/{M} _ {\odot}) $
