THE FOURSTAR GALAXY EVOLUTION SURVEY (ZFOURGE): ULTRAVIOLET TO FAR-INFRARED CATALOGS, MEDIUM-BANDWIDTH PHOTOMETRIC REDSHIFTS WITH IMPROVED ACCURACY, STELLAR MASSES, AND CONFIRMATION OF QUIESCENT GALAXIES TO z ∼ 3.5*

The FourStar galaxy evolution survey (ZFOURGE) is a 45 night legacy program with the FourStar nearinfrared camera on Magellan and one of the most sensitive surveys to date. ZFOURGE covers a total of 400 arcmin(2) in cosmic fields CDFS, COSMOS and UDS, overlapping CANDELS. We present photometric catalogs comprising > 70,000 galaxies, selected from ultradeep K-s-band detection images (25.5-26.5 AB mag, 5 sigma, total), and >80% complete to K-s. <. 25.3-25.9 AB. We use 5 near-IR medium-bandwidth filters (J(1), J(2), J(3), H-s, H-l) as well as broad-band K-s at 1.05-2.16 mu m to 25-26 AB at a seeing of similar to 0 ''. 5. Each field has ancillary imaging in 26-40 filters at 0.3-8 mu m. We derive photometric redshifts and stellar population properties. Comparing with spectroscopic redshifts indicates a photometric redshift uncertainty sigma(z) = 0.010, 0.009, and 0.011 in CDFS, COSMOS, and UDS. As spectroscopic samples are often biased toward bright and blue sources, we also inspect the photometric redshift differences between close pairs of galaxies, finding sigma(z,pairs) =. 0.01-0.02 at 1. < z < 2.5. We quantify how sigma(z,pairs) depends on redshift, magnitude, spectral energy distribution type, and the inclusion of FourStar medium bands. sigma(z,pairs) is smallest for bright, blue star-forming samples, while red star-forming galaxies have the worst sigma(z,pairs.) Including FourStar medium bands reduces sigma(z,pairs) by 50% at 1.5 < z < 2.5. We calculate star formation rates (SFRs) based on ultraviolet and ultradeep far-IR Spitzer/MIPS and Herschel/PACS data. We derive rest-frame U - V and V - J colors, and illustrate how these correlate with specific SFR and dust emission to z = 3.5. We confirm the existence of quiescent galaxies at z similar to 3, demonstrating their SFRs are suppressed by > x15.
