The Next Generation Deep Extragalactic Exploratory Public Near-Infrared Slitless Survey Epoch 1 (NGDEEP-NISS1): Extra-Galactic Star-formation and Active Galactic Nuclei at 0.5 < z < 3.6
arxiv(2023)
摘要
The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) survey
program was designed specifically to include Near Infrared Slitless
Spectroscopic observations (NGDEEP-NISS) to detect multiple emission lines in
as many galaxies as possible and across a wide redshift range using the Near
Infrared Imager and Slitless Spectrograph (NIRISS). We present early results
obtained from the the first set of observations (Epoch 1, 50% of the
allocated orbits) of this program (NGDEEP-NISS1). Using a set of independently
developed calibration files designed to deal with a complex combination of
overlapping spectra, multiple position angles, and multiple cross filters and
grisms, in conjunction with a robust and proven algorithm for quantifying
contamination from overlapping dispersed spectra, NGDEEP-NISS1 has achieved a
3σ sensitivity limit of 2 × 10^-18 erg/s/cm^2. We
demonstrate the power of deep wide field slitless spectroscopy (WFSS) to
characterize the star-formation rates, and metallicity ([OIII]/Hβ), and
dust content, of galaxies at 1更多
