Upper limit on HF(1-0) absorption in a dusty star-forming galaxy at : Constraints on early fluorine enrichment
Akiyoshi Tsujita, Chiaki Kobayashi, Yuki Yoshimura +10
Wolf-Rayet (WR) stars have recently attracted attention as possible drivers of early chemical enrichment, including the production of fluorine, whose nucleosynthetic origin remains…
CLASSY XIV: The Nitrogen Exception -- Multi-Phase Enrichment and Feedback in High- Analogs
Bethan L. James, Valentina Abril-Melgarejo, Karla Z. Arellano-Córdova +13
We present a first-of-its-kind analysis of the metal content across two interstellar medium (ISM) phases in a sample of 31 local star-forming galaxies from the COS Legacy Archive S…
A Fleeting GLIMPSE of N/O Enrichment at Cosmic Dawn: Evidence for Wolf Rayet N Stars in a z = 6.1 Galaxy
Danielle A. Berg, Rohan P. Naidu, John Chisholm +18
We present the discovery of extreme nitrogen enrichment by Wolf Rayet nitrogen stars (WN) in the metal-poor (~10% Z_odot), lensed, compact (R_eff ~ 20 pc) galaxy RXCJ2248 at z=6.1,…
Gradients of Absorption Line Strengths in Elliptical Galaxies
Chiaki Kobayashi, Nobuo Arimoto
We have re-studied line-strength gradients of 80 elliptical galaxies. Typical metallicity gradients are d[Fe/H]/dlogr = -0.3. The metallicity gradients do not correlate with any ph…
