Precise C-N-O Abundances of Individual Galaxies in the First Billion Years from Ultra-Deep, Rest-UV-to-Optical JWST Spectroscopy
Raunaq Singh Rai, Guido Roberts-Borsani, Ryan Sanders +8
We present ultra-deep JWST/NIRSpec spectroscopy of nine star-forming galaxies at in the GOODS-N field, drawn from the Origins of Metal Enrichment in Galaxie…
The AURORA Survey: Determining the Production Mechanism for OI Emission in Star-forming Galaxies at Cosmic Noon
Leonardo Clarke, Alice E. Shapley, Zhiwei Shao +11
We analyze deep JWST/NIRSpec observations of 58 star-forming galaxies at in the AURORA survey to investigate the origin of the permitted OI emission feature.…
The JADES Mass-Metallicity and Fundamental Metallicity Relations at Using New High-Redshift Metallicity Calibrations
Natalie Lam, Leonardo Clarke, Alice E. Shapley +5
We present measurements of the mass-metallicity relation (MZR) and fundamental metallicity relation (FMR) at using stacked JWST/NIRSpec spectra of 601 star-forming gala…
The AURORA Survey: Multiple Balmer and Paschen Emission Lines for Individual Star-forming Galaxies at z=1.5-4.4. II. Implications for Nebular Dust Corrections, Nebular SFRs, and Differential Reddening
Naveen A. Reddy, Alice E. Shapley, Ryan L. Sanders +10
We discuss the implications of the nebular dust attenuation curves derived for 24 galaxies at z=1.5-4.4 with multiple detections of HI Balmer and Paschen recombination emission lin…
Balmer Decrements and Nebular-Stellar Reddening in JADES Galaxies at
Shreya Karthikeyan, Leonardo Clarke, Alice E. Shapley +5
We aim to characterize nebular and stellar reddening in star-forming galaxies as a function of global galaxy properties (stellar mass, SFR, metallicity) at . We also…
Emission-line Diagnostics at : A Probe of the Ionizing Spectrum and Enhancement Beyond Cosmic Noon
Leonardo Clarke, Natalie Lam, Alice E. Shapley +5
We analyze several key rest-optical emission-line ratios in a sample of 828 galaxies as well as composite spectra from JADES DR3 in the range . These emission-line rat…
