The JWST EXCELS survey: an extremely metal-poor galaxy at hosting an unusual population of massive stars
F. Cullen, A. C. Carnall, D. Scholte +14
We present an analysis of the rest-frame optical (Å) spectrum of a star-forming galaxy at from JWST/…
New Ionization Models and the Shocking Nitrogen Excess at z > 5
Sophia R. Flury, Karla Z. Arellano-Córdova, Edward C. Moran +1
The new era of galaxy evolution studies hearkened in by JWST has led to the discovery of z > 5 galaxies exhibiting excess nitrogen with log(N/O)~1 dex or more than expected from lo…
The JWST EXCELS survey: direct estimates of C, N, and O abundances in two relatively metal-rich galaxies at
K. Z. Arellano-Córdova, F. Cullen, A. C. Carnall +14
We present a spectroscopic analysis of two star-forming galaxies at observed with JWST/NIRSpec as part of the EXCELS survey. The detection of the CIII]~1906,09, [OII…
The JWST EXCELS survey: tracing the chemical enrichment pathways of high-redshift star-forming galaxies with O, Ar and Ne abundances
T. M. Stanton, F. Cullen, A. C. Carnall +11
We present an analysis of eight star-forming galaxies with from the JWST EXCELS survey for which we obtain robust chemical abundance estimates for the …
Generalized ([OIII])-(HeI) Discrepancies in Ionized Nebulae: Possible Evidence of Case B Deviations and Temperature Inhomogeneities
J. E. Méndez-Delgado, E. D. Skillman, E. Aver +11
The physics of recombination lines (RLs) in the HeI singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the intensities of HeI singl…
CHAOS VIII: Far-Ultraviolet Spectra of M101 and The Impact of Wolf-Rayet Stars
Danielle A. Berg, Evan D. Skillman, John Chisholm +8
We investigate the stellar and nebular properties of 9 H II regions in the spiral galaxy M101 with far-ultraviolet (FUV; ~900-2000 Å) and optical (~3200-10000 Å) spectra. We detect…
