Nitrogen abundances in star-forming galaxies 2.2 Gyr after the Big Bang are not elevated
D. Schaerer, Y. I. Izotov, R. Marques-Chaves +22
Using deep medium-resolution JWST rest-optical spectra of a sample of typical star-forming galaxies (Lyman break galaxies and Lyman- emitters) from the LyC22 survey at $z \sim 3…
GLIMPSE-D: Metallicity Decline in Faint Galaxies: Implications for [O III]+Hb Luminosity Function and Reionisation Budget
Damien Korber, Daniel Schaerer, Rui Marques-Chaves +13
We report the measurement of the R3=[O III]5008/Hb ratios for 54 galaxies in the GLIMPSE-D survey. Thanks to gravitational lensing, our sample includes galaxies with -20 < Muv < -1…
N-emitters as possible sign-posts of GC formation
D. Schaerer, R. Marques-Chaves, H. Atek +7
Based on the finding of unusual chemical abundance ratios of N-emitters, which resemble those of globular cluster (GC) stars, their compactness, high ISM densities and other proper…
Discovery of new N-emitters over a wide redshift range
I. Morel, D. Schaerer, R. Marques-Chaves +5
JWST observations have revealed rare galaxies with UV spectra exhibiting intense lines of nitrogen, indicative of super-solar N/O abundances at low metallicity. To better understan…
A GLIMPSE into the very faint-end of the H+[OIII]4960,5008 luminosity function at z=7-9 behind Abell S1063
Damien Korber, Iryna Chemerynska, Lukas J. Furtak +12
We use the ultra-deep GLIMPSE JWST/NIRCam survey to constrain the faint-end of the H+[OIII]4960,5008 luminosity function (LF) down to erg/s at z=7-9 behind the len…
LMC+: Large-scale mapping of [CII] and [OIII] in the LMC molecular ridge, I. Dataset and line ratio analyses
C. Fischer, S. C. Madden, A. Krabbe +29
The fundamental process of star formation in galaxies involves the interplay between the fueling of star formation via molecular gas and the feedback from recently formed massive s…
