Title: The NEWFIRM HETDEX Survey - Probing the Growth of Galaxies with Cosmic Time

Abstract: We propose NEWFIRM $K$-band imaging over a 28 deg$^2$ equatorial region within SDSS Stripe 82 to finish building a unique and important extragalactic legacy field. This field will soon have $\sim0,000 \lya-based redshifts at 2 $< z <$ 3.5 from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX), deep imaging at 3.6$\mu$m and 4.5$\mu$m from the {\it Spitzer}-HETDEX Exploratory Large Area survey, far-IR data from {\it Herschel}, and deep optical imaging from the Dark Energy Survey. The addition of NEWFIRM $K$-band data will allow us to 1) Measure robust extinction-corrected star-formation rates (SFRs) down to 10 M\sol\ yr$^$ at stellar masses of 10$^$ M\sol; 2) Calculate precise photometric redshifts for the non-\lya\ emitters in the sample; and 3) Study how the SFR depends on the dark matter halo mass and local environment. This large survey, together with the spectroscopic completeness and accurate halo mass measurements from HETDEX, is crucial to allow a comprehensive analysis at $z \sim$ 2 -- 3 out to high halo masses (log (\mh/M\sol)$_{z=2.5}$ $>$ 13). This mass regime is particularly important, as it is where we track the progenitors of today's richest galaxy clusters and where the relationship between star formation and different modes of gas accretion is poorly constrained.
