A search for the first galaxies across deg of JWST imaging: new evidence for a rapid decline in star-formation activity at

D. J. McLeod, J. S. Dunlop, R. J. McLure +20

We present a new determination of the evolving galaxy UV luminosity function (LF) over the extreme redshift range , based on a wide-area search of 0.6 deg of JW…

The JWST EXCELS Survey: gas-phase metallicity evolution at 2 < z < 8

T. M. Stanton, F. Cullen, A. C. Carnall +15

We present an analysis of the gas-phase mass-metallicity relationship (MZR) and fundamental metallicity relationship (FMR) for star-forming galaxies at from the JW…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Northern Local Star-forming Dwarf Galaxies. Analogues of the First Galaxies and Probes of the Cosmic Metallicity Scale

C. Esteban, J. M. Vilchez, J. García-Rojas +15

Star-forming dwarf galaxies in the local Universe, especially extremely metal-poor ones, can be considered analogous to early galaxies of the Epoch of Reionization (z >= 6). Curren…

The JWST EXCELS Survey: A spectroscopic investigation of the ionizing properties of star-forming galaxies at 1<z<8

R. Begley, R. J. McLure, F. Cullen +11

Charting the Epoch of Reionization demands robust assessments of what drives the production of ionizing photons in high-redshift star-forming galaxies (SFGs), and requires better p…

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 (Ã ) spectrum of a star-forming galaxy at from JWS…

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, [O…
