Abstract:
We present a catalog of 717 candidate galaxies at z>8 selected from
125 square arcmin of NIRCam imaging as part of the JWST Advanced Deep
Extragalactic Survey (JADES). We combine the full JADES imaging data
set with data from the JWST Extragalactic Medium Survey and First
Reionization Epoch Spectroscopic COmplete Survey (FRESCO) along with
extremely deep existing observations from Hubble Space Telescope
(HST)/Advanced Camera for Surveys (ACS) for a final filter set that
includes 15 JWST/NIRCam filters and five HST/ACS filters. The
high-redshift galaxy candidates were selected from their estimated
photometric redshifts calculated using a template-fitting approach,
followed by visual inspection from seven independent reviewers. We
explore these candidates in detail, highlighting interesting resolved
or extended sources, sources with very red long-wavelength slopes, and
our highest-redshift candidates, which extend to zphot ∼18. Over 93%
of the sources are newly identified from our deep JADES imaging,
including 31 new galaxy candidates at zphot>12. We also investigate
potential contamination by stellar objects, and do not find strong
evidence from spectral energy distribution fitting that these faint
high-redshift galaxy candidates are low-mass stars. Using 42 sources
in our sample with measured spectroscopic redshifts from NIRSpec and
FRESCO, we find excellent agreement to our photometric redshift
estimates, with no catastrophic outliers and an average difference of
<Δz=zphot-zspec≥0.26. These sources comprise one of the most
robust samples for probing the early buildup of galaxies within the
first few hundred million years of the Universe's history.
Description:
In this paper, we will discuss galaxy candidates selected from the
JWST NIRCam imaging in both GOODS-S, with observations taken on UT
2022 February 29 through 2022 October 10 (Program 1180, PI: Eisenstein),
and GOODS-N, with observations taken on UT 2023 February 3 through
2023 February 7 (Program 1181, PI: Eisenstein).
In addition, a set of NIRCam parallels (9.8 square arcmin each) were
observed during NIRSpec observation PID 1210 (PI: Ferruit) on UT
2022 October 20 to 2022 October 24 within and southwest of the JADES
Medium footprint in GOODS-S.
Another set of NIRCam observations (9.8 square arcmin) parallel to
NIRSpec PID 1286 (PI: Ferruit) were observed on UT 2023 January 12 to
2023 January 13 to the northwest (NW) of the JADES Deep footprint in
GOODS-S.
These data were partly presented in both Robertson+ (2023NatAs...7..611R 2023NatAs...7..611R)
as well as Tacchella+ (2023ApJ...952...74T 2023ApJ...952...74T), although here we combine
the full suite of JADES data observed as of 2023 February 8.
The total current survey area of the JADES GOODS-S is 67 square arcmin,
with 27 square arcmin for the JADES Deep program and 40 square arcmin
for the JADES Medium program. The filters used for JADES Deep are
NIRCam F090W, F115W, F150W, F200W, F277W, F335M, F356W, F410M, and
F444W (λ=0.8-5.0um), while JADES Medium uses the same filters
without F335M. For the 1286 parallel, the JADES observations include
the F070W filter.
The total current area of the NIRCam GOODS-N program is
58 square arcmin. The NIRCam filters observed for GOODS-N are F090W,
F115W, F150W, F200W, F277W, F335M, F356W, F410M, and F444W
(λ=0.8-5.0um). The GOODS-N observations are separated into two
portions: the NW portion, which covers 30.4 square arcmin, and a
southeast (SE) portion, which covers 27.6 square arcmin.
We also include observations taken for the JWST Extragalactic
Medium-band Survey (JEMS; Williams+ 2023ApJS..268...64W 2023ApJS..268...64W). These data,
which are part of program PID 1963 (PIs: Williams, Tacchella, Maseda)
were taken on UT 2022 October 12. For this study, we use the NIRCam
data from JEMS, which cover the Ultra-Deep Field (UDF) by the NIRCam A
module, with the NIRCam B module to the SW, spanning the JADES Deep
and Medium portions, for a total area of 10.1 square arcmin. The
NIRCam observations in the JEMS survey were taken with the F182M,
F210M, F430M, F460M, and F480M filters.
We also supplement our observations with NIRCam data from the First
Reionization Epoch Spectroscopic COmplete Survey (FRESCO; PID 1895,
PI: Oesch). While nominally a NIRCam grism survey across GOODS-S and
GOODS-N, we use the FRESCO F182M, F210M, and F444W imaging of GOODS-S
and GOODS-N to supplement the filters available in JADES. We use the
FRESCO grism data as well as the NIRSpec observations from PIDs 1210
and 1286 to measure spectroscopic redshifts for sources within our
sample.
The GOODS-S and GOODS-N regions have been the target of deep HST
observations, and we utilize existing HST/Advanced Camera for Surveys
(ACS) and WFC3 mosaics. We use data in the HST/ACS F435W, F606W,
F775W, F814W, and F850LP filters.
Throughout this paper, we assume a Planck Col. (2020A&A...641A...6P 2020A&A...641A...6P)
cosmology with H0=67.4km/s/Mpc, ΩM=0.315, and
ΩΛ=0.685. All magnitudes are provided using the AB
magnitude system.
