3D-HST Data Release v3.0: Extremely Deep Spectra in the UDF and WFC3 Mosaics in the 3D-HST/CANDELS Fields
Abstract
3D-HST is a 248-orbit Treasury program to provide WFC3 and ACS grism spectroscopy over four extra-galactic fields (AEGIS, COSMOS, GOODS-South, and UDS), augmented with previously obtained data in GOODS-North. We present a new data release of the 3D-HST survey, version v3.0. This release follows the initial v0.5 release that accompanied the survey description paper (Brammer et al. 2012). The new v3.0 release includes the deepest near-IR HST grism spectra currently in existence, extracted from the 8-17 orbit depth observations in the Hubble Ultra Deep Field. Contamination-corrected 2D and 1D spectra, as well as derived redshifts, are made available for >250 objects in this 2'x2'field. The spectra are of extraordinary quality, and show emission features in many galaxies as faint as F140W=26-27, absorption features in quiescent galaxies at z~2, and several active galactic nuclei. In addition to these extremely deep grism data we provide reduced WFC3 F125W, F140W, and F160W image mosaics of all five 3D-HST/CANDELS fields.
