TL;DR
The HDUV survey provides the deepest high-resolution UV imaging over ~100 arcmin2 in two filters, enabling advanced studies of faint star-forming galaxies, ionizing photon escape, and galaxy evolution at z~1-3.
Contribution
It offers the first deep, wide-area UV imaging data in the GOODS/CANDELS fields, combining new and archival data with a novel alignment approach.
Findings
Deep UV images reach 27.5-28.0 mag (5sigma) in 0.4" apertures.
Provides a complete sample of faint star-forming galaxies at z~1-3.
Enables studies of ionizing photon escape and galaxy structural evolution.
Abstract
We present the Hubble Deep UV Legacy Survey (HDUV), a 132 orbit imaging program with the WFC3/UVIS camera onboard the Hubble Space Telescope (HST). The HDUV extends and builds on the few previous UV imaging surveys in the two GOODS/CANDELS-Deep fields to provide deep images over a total area of ~100 arcmin2 in the two filters F275W and F336W. Our release also includes all the F275W imaging data taken by the CANDELS survey, which were aligned using a novel approach and combined with the HDUV survey data. By reaching depths of 27.5-28.0 mag (5sigma, in 0.4" apertures), these are the deepest high-resolution UV data over such a large area taken to date. Such unique UV imaging enables a wide range of science by the community. Among the main goals of the HDUV survey are: (1) provide a complete sample of faint star-forming galaxies at z~1-3, (2) constrain the ionizing photon escape fraction…
