Abstract:
Wide Field Slitless Spectroscopy (WFSS) provides a powerful tool for
detecting strong line emission in star-forming galaxies (SFGs) without
the need for target preselection. As part of the GLASS-JWST Early
Release Science (ERS) program, we leverage the near-infrared
wavelength capabilities of NIRISS (1-2.2µm) to observe rest-optical
emission lines out to z∼3.4, to a depth and with a spatial resolution
higher than ever before (Hα to z<2.4; [OIII]+Hβ to z<3.4).
In this Letter we constrain the rest-frame [OIII]λ5007
equivalent width (EW) distribution for a sample of 76 1<z<3.4 SFGs in
the A2744 Hubble Frontier Field and determine an abundance fraction of
extreme emission line galaxies with EW>750Å in our sample to be
12%. We determine a strong correlation between the measured Hβ
and [OIII]λ5007 EWs, supporting that the high [OIII]λ5007
EW objects require massive stars in young stellar populations to
generate the high-energy photons needed to doubly ionize oxygen. We
extracted spectra for objects up to 2mag fainter in the near-infrared
than previous WFSS studies with the Hubble Space Telescope. Thus, this
work clearly highlights the potential of JWST/NIRISS to provide
high-quality WFSS data sets in crowded cluster environments.
Description:
As part of the GLASS-ERS strategy, we use the Wide Field Slitless
Spectroscopy (WFSS) mode of the JWST/NIRISS instrument to conduct
1.0-2.2um low-resolution spectroscopy (average spectral resolution of
R∼150) over the A2744 region. The NIRISS component of the GLASS-ERS
survey utilizes a single pointing centered on the core of the A2744
cluster, giving a full area of 2.2'x2.2'. The WFSS observations and
associated direct imaging are obtained using the F115W, F150W, and
F200W blocking filters. For the full details of the GLASS-ERS data
acquisition, observing strategy, and data reduction we refer the
reader to Treu+ (2022ApJ...935..110T 2022ApJ...935..110T) and
Roberts-Borsani+ (2022ApJ...938L..13R 2022ApJ...938L..13R).
In this study we only measure integrated line properties of galaxies
and we refer the reader to Wang+ 2022ApJ...938L..16W 2022ApJ...938L..16W (Paper IV of this
series) for a GLASS-ERS study of spatially resolved emission line
properties.

Note on table1.dat: At this early stage of the mission, there is ongoing
development of JWST calibration files and reduction pipelines, which
means the quality of the extracted NIRISS data will likely improve
over time. The NIRISS data reduction used in this work utilised the
following pedigree of data products: CAL_VER=1.5.2, CRDS_VER=11.13.1
and CRDSCTX=jwst0881.pmap.
