Early results from GLASS-JWST. VI. NIRISS WFFS

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 (1-2.2{mu}m) to observe rest-optical emission lines out to z~3.4, to a depth and with a spatial resolution higher than ever before (H{alpha} to z<2.4; [OIII]+H{beta} to z<3.4). In this Letter we constrain the rest-frame [OIII]{lambda}5007 equivalent width (EW) distribution for a sample of 76 1<z750{AA} in our sample to be 12%. We determine a strong correlation between the measured H{beta} and [OIII]{lambda}5007 EWs, supporting that the high [OIII]{lambda}5007 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.
