Abstract:
We present extremely deep Hubble Space Telescope (HST) Wide Field
Camera 3 (WFC3) observations of the MUSE Ultra Deep Field. This unique
region of the sky contains two quasars at z∼3.22 that are separated by
only ∼500kpc, providing a stereoscopic view of gas and galaxies in
emission and absorption across ∼10 billion years of cosmic time. We
have obtained 90 orbits of HST WFC3 G141 near-infrared grism
spectroscopy of this field in a single pointing, as well as 142hr of
optical spectroscopy with the Very Large Telescope Multi Unit
Spectroscopic Explorer (MUSE). The WFC3 (F140W, F125W, and F336W) and
archival WFPC2 (F702W and F450W) imaging provides five-filter
photometry that we use to detect 3375 sources between z∼0-6, including
1536 objects in a deep central pointing with both spectroscopic and
photometric coverage. The F140W and F336W mosaics reach exceptional
depths of mAB∼28 and 29, respectively, providing near-infrared and
rest-frame ultraviolet information for 1580 sources, and we reach
5σ continuum detections for objects as faint as mAB∼27 in the
grism spectra. The extensive wavelength coverage of MUSE and WFC3
allows us to measure spectroscopic redshifts for 419 sources, down to
galaxy stellar masses of log(M/M☉)∼7 at z∼1-2. In this
publication, we provide the calibrated HST data and source catalogs as
High Level Science Products for use by the community, which includes
photometry, morphology, and redshift measurements that enable a
variety of studies aimed at advancing our models of galaxy formation
and evolution in different environments.
Description:
In the NIR, we have observed the MUSE Ultra Deep Field (MUDF)
field with WFC3/IR onboard HST, obtaining 90 orbits of G141 grism
spectroscopy and F140W imaging (Program ID 15637, PI: M. Rafelski &
M. Fumagalli); observations were obtained in Cycle 26 between
2019-August-10 and September-14, with four failed visits repeated in
2020-March and September. In addition to the HST WFC3/IR F140W
imaging, we observed the field over a single-orbit with the F125W
filter on 2020-March-23.
In the optical, we take advantage of archival HST WFPC2 imaging
through the F702W and F450W filters (Program ID 6631, PI: P. Francis).
The field was observed with the F450W filter for eight orbits between
2000 August 31 and September 2, while the F702W observations encompass
six orbits on 1999 August 23.
In the NUV, we have obtained eight orbits of HST WFC3/UVIS imaging
using the F336W filter (Program ID 15968, PI: M. Fossati). These
observations were gathered during two visits on 2020-May-5 and
2020-July-12.
