VizieR Online Data Catalog: Extreme emission-line galaxies at z~4-9 (Llerena+, 2024)

The complete CEERS program involves imaging with the NIRCam short and long-wavelength channels in ten pointings, observed as coordinated parallels to primary observations with the NIRSpec and the MidInfrared Instrument (MIRI). In this paper, we used photometric data from NIRCam and NIRSpec spectra. The CEERS observations were split into two epochs. The first epoch was executed in June 2022, and the second in December 2022. An additional third epoch of NIRSpec prism spectra (pointings 11 and 12) was taken in February 2023, due to the MSA short that affected prism 9 + 10 in December 2022. In total, 10 pointings were taken with NIRCam imaging, including seven filters per pointing (F115W, F150W, F200W, F277W, F356W, F410M, and F444W), reaching 5σ depths of ~28.5-29.2(AB)mag for point sources for a total area of ~97arcmin².

We used version v0.51.2 of the CEERS Photometric Catalogs (Finkelstein et al. in prep.).

We estimate the fluxes of [OIII]+Hβ and Hα based on the observed photometry. Based on the line fluxes, we estimate the rest-frame EWs. We report our estimations in Table 2.

To obtain the physical properties of the sample of EELGs, we perform SED fitting with only JWST photometry to have homogeneous data. We consider the entire set of filters used in the CEERS surveys, which are F115W, F150W, F200W, F277W, F356W, F410M, and F444W. We report the obtained parameters in Table 3.
