Abstract:
In 2022 November, the James Webb Space Telescope (JWST) returned deep
near-infrared images of A2744-a powerful lensing cluster capable of
magnifying distant, incipient galaxies beyond it. Together with
existing Hubble Space Telescope (HST) imaging, this publicly available
data set opens a fundamentally new discovery space to understand the
remaining mysteries of the formation and evolution of galaxies across
cosmic time. In this work, we detect and measure some 60000 objects
across the 49arcmin2 JWST footprint down to a 5σ limiting
magnitude of ∼30mag in 0.32" apertures. Photometry is performed using
circular apertures on images matched to the point-spread function
(PSF) of the reddest NIRCam broad band, F444W, and cleaned of bright
cluster galaxies and the related intracluster light. To give an
impression of the photometric performance, we measure photometric
redshifts and achieve a σNMAD∼0.03 based on known, but
relatively small, spectroscopic samples. With this paper, we publicly
release our HST and JWST PSF-matched photometric catalog with
optimally assigned aperture sizes for easy use, along with single
aperture catalogs, photometric redshifts, rest-frame colors, and
individual magnification estimates. These catalogs will set the stage
for efficient and deep spectroscopic follow up of some of the first
JWST-selected samples in summer of 2023.
Description:
The photometric catalogs presented herein include all public
JWST/NIRCam imaging of A2744 available to date: the Ultradeep NIRSpec
and NIRCam ObserVations before the Epoch of Reionization (UNCOVER)
Treasury survey (PIs: Labbe & Bezanson, JWST-GO-2561;
Bezanson+ 2022arXiv221204026B 2022arXiv221204026B), the Early Release Science (ERS)
GLASS-JWST program (PI: Treu, JWST-DD-ERS-1324; Treu+ 2022ApJ...935..110T 2022ApJ...935..110T),
and a Directors Discretionary Time (DDT) program (JWST-DD-2756, PI: Chen).
Our data set combines the deep NIRCam imaging with 4-6hr exposures in
seven filters (F115W, F150W, F200W, F277W, F356W, F410M, and F444W)
from UNCOVER, with the ultradeep imaging with 9-14hr exposures from
GLASS-ERS in seven filters (F090W, F115W, F150W, F200W, F277W, F356W,
and F444W). Additionally, the DDT program includes two epochs of
NIRCam imaging in six filters (F115W, F150W, F200W, F277W, F356W, and
F444W), totaling ∼1hr per filter. See Section 2.1.
A wide range of imaging of the A2744 cluster and surrounding area
exists within the public HST archive. Briefly, we summarize the
programs relevant herein. Program HST-GO-11689 (PI: Dupke) and
HST-GO-13386 (PI: Rodney) include deep HST/Advanced Camera for Surveys
(ACS) imaging in the cluster center in three filters (F435W, F606W,
and F814W), with program HST-DD-13495 (PI: Lotz;
Lotz+ 2017ApJ...837...97L 2017ApJ...837...97L) acquiring complementary deep HST/Wide Field
Camera 3 (WFC3) observations in four filters (F105W, F125W, F140W, and
F160W). While each of the above programs are (deep) individual
pointings limited by the ACS and WFC3 fields of view (FOVs),
respectively, the data were later expanded by a factor of 4 with
shallower imaging in two ACS filters (F606W and F814W) and three WFC3
filters (F105W, F125W, and F160W) by the BUFFALO survey (Program
HST-GO-15117, PIs: Steinhardt & Jauzac; Steinhardt+ 2020ApJS..247...64S 2020ApJS..247...64S).
Most recently, the deep optical coverage was further expanded by
Program JWST-DD-17231 (PI: Treu). See Section 2.2.
All magnitudes in this paper are expressed in the AB system, for which
a flux fν of 10nJy (10-28erg/cm2/s/Hz) corresponds to
ABv=28.9-2.5log10(fv/uJy). When computing physical properties
such as rest-frame fluxes, we adopt a standard ΛCDM cosmology
with H0=70km/s/Mpc, ΩM=0.3, and ΩΛ=0.7.
