Abstract:
We describe the NIRSpec component of the JWST Deep Extragalactic
Survey (JADES), and provide deep spectroscopy of 253 sources targeted
with the NIRSpec micro-shutter assembly in the Hubble Ultra Deep Field
and surrounding GOODS-South. The multi-object spectra presented here
are the deepest so far obtained with JWST, amounting to up to 28 hours
in the low-dispersion (R∼30-300) prism, and up to 7 hours in each of
the three medium-resolution R~=1000 gratings and one high-dispersion
grating, G395H (R~=2700). Our low-dispersion and medium- dispersion
spectra cover the wavelength range 0.6-5.3um. We describe the
selection of the spectroscopic targets, the strategy for the
allocation of targets to micro-shutters, and the design of the
observations. We present the public release of the reduced 2D and 1D
spectra, and a description of the reduction and calibration process.
We measure spectroscopic redshifts for 178 of the objects targeted
extending up to z=13.2. We present a catalogue of all emission lines
detected at S/N>5, and our redshift determinations for the targets.
Combined with the first JADES NIRCam data release, these public JADES
spectroscopic and imaging datasets provide a new foundation for
discoveries of the infrared universe by the worldwide scientific
community.
Description:
In Table F.1, the ID of the closest match within 0.2 in the NIRCam
data release catalogue (Rieke et al., 2023ApJS..269...16R 2023ApJS..269...16R) is given;
the RA and Dec are those supplied to the eMPT for target allocation and
for path loss determination. The majority of the remaining targets
have counterparts in our HST-based catalogue drawn from one of Skelton
et al. (2014ApJS..214...24S 2014ApJS..214...24S, Cat. J/ApJS/214/24), Guo et al.
(2013ApJS..207...24G 2013ApJS..207...24G, Cat. J/ApJS/207/24), Rafelski et al.
(2015AJ....150...31R 2015AJ....150...31R, Cat. J/AJ/150/31), and/or Whitaker et al.
(2019ApJS..244...16W 2019ApJS..244...16W, Cat. J/ApJS/244/16). Targets which do not have a
counterpart in any of these catalogues are marked with an asterisk,
representing only a small number of targets.
In Table F.3 (emission lines from the prism spectra), note that some
lines (notably, H-beta, [OIII]5007 and [OIII]4959) are reported
independently at high-redshift, but are reported as blends at lower
redshift due to the reduced spectral resolution of the prism at
shorter wavelengths. We also caution that some fluxes reported here as
being for individual lines may feature non-negligible contributions
from fainter lines (e.g. H-alpha from [NII], or [NeIII]3869 from
HeI3889). In these cases, the reported flux will represent the total
flux of the observed emission feature.
