Chemical abundance patterns at z=1-7: Carbon, Nitrogen, Neon, Sulphur, and Argon abundances from JWST spectroscopy
E. Cataldi, F. Belfiore, M. Curti +22
The relative abundances of chemical elements in the interstellar medium (ISM) trace the history of star formation and chemical enrichment in galaxies. We investigate the abundance…
Confirming membership in Local Group galaxies with the Dark Energy Spectroscopic Instrument Data Release 1
Federico Sestito, Chiaki Kobayashi
We use the Dark Energy Spectroscopic Instrument Data Release 1 (DESI DR1) to identify stellar members of the Local Group dwarf galaxies. We cross-match DESI targets with candidate…
Tracing nitrogen enrichment across cosmic time with JWST
E. Cataldi, F. Belfiore, M. Curti +22
We present a comprehensive analysis of the nitrogen-to-oxygen (N/O) abundance ratio in a sample of ~ 660 star-forming galaxies at redshift z ~ 1-6, with a median redshift of z = 3.…
MARTA: Temperature-temperature relationships and strong-line metallicity calibrations from multiple auroral-line detections at cosmic noon
E. Cataldi, F. Belfiore, M. Curti +22
We present the first results from MARTA (Measuring Abundances at high Redshift with the T Approach), a programme leveraging ultra-deep, medium-resolution JWST/NIRSpec spectrosc…
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…
Direct measurements of carbon and sulfur isotope ratios in the Milky Way
Y. T. Yan, C. Henkel, C. Kobayashi +7
With the IRAM 30 meter telescope, we performed observations of the = 2-1 transitions of CS, CS, CS, CS, CS, CS, and CS a…
