The NEWFIRM Medium Band Survey II: Hunting Monster Galaxies

Overview

The NOAO NEWFIRM Medium Band Survey-II (NMBS2) uses five custom medium-bandwidth filters over the wavelength range 1-1.8 μm + K-band to measure galaxy redshifts. The goal is to identify the most luminous and massive galaxies yet known at z > 2.
