Abstract. I will review results from
the ZFOURGE survey, a new imaging campaign to track galaxy evolution over
the last 12 billion years. Deep Magellan near-infrared imaging taken with
medium-bandpass filters allows us to finely sample galaxy spectral energy
distributions and derive unprecedented photometric redshifts and stellar
population parameters at z > 1.5. Using ultra-deep Ks-band imaging (25.5-26
AB mag. 5-sigma) in 3 deep fields (COSMOS, UDS, GOODS-S) to select galaxies,
we have constructed large stellar mass-limited galaxy samples to redshift
z=4. With these catalogs we have: (1) conducted an evolutionary study of
the star-forming and quiescent galaxy stellar mass functions to a redshift
of z=3, (2) demonstrated the existence of quiescent galaxies out to z=4,
(3) performed a general census of the massive galaxy population at z=3-4
(4) tracked the evolution of radio and X-ray active galactic nuclei host
galaxies and (5) discovered one of the most distant galaxy clusters known
so far.
