Gas-Phase Metallicity and Nitrogen Abundances in Low-Mass Galaxies Down to $M_{⋆} ≃ 1 0^{5.7} M_{⊙}$ at $z ≃ 4.5$ -- $10.1$ from JWST Lensing Cluster Surveys

Hiroya Umeda, Masami Ouchi, Kimihiko Nakajima +7

We analyze 405 deep JWST/NIRSpec spectra of star-forming galaxies at $z = 4.5$ -- $10.1$ from DREAMS and other lensing-cluster surveys to study chemical enrichment in intrinsically fai…

Chemical Abundance Ratios of Nitrogen Rich Galaxies Identified at $z \sim 6 - 12$ : Observational Demographics and Models

Kuria Watanabe, Masami Ouchi, Kimihiko Nakajima +13

We present chemical abundance ratios of 8 nitrogen-rich ([N/O] $> 0.3$ ) galaxies at $z \sim 6 - 12$ identified by the first 4 years of the JWST observations, and compare these ratios wi…
