Globular cluster abundance patterns inherited from giant molecular clouds
William McClymont, Vasily Belokurov, Sandro Tacchella +16
Globular clusters exhibit large star-to-star variations and anticorrelations in their light element abundances that are commonly interpreted in terms of in-cluster self-enrichment,…
Cosmic evolution of the helium and oxygen abundances in type 2 Active Galactic Nuclei: Helium-loud AGNs
O. L. Dors, M. Armah, G. F. Hägele +14
We derive the helium and oxygen abundances in the Narrow Line Regions (NLRs) of 84 Active Galactic Nuclei (AGNs) spanning two redshift ranges: 65 objects at and 19…
Chemical Abundance Ratios of Nitrogen Rich Galaxies Identified at : Observational Demographics and Models
Kuria Watanabe, Masami Ouchi, Kimihiko Nakajima +13
We present chemical abundance ratios of 8 nitrogen-rich ([N/O]) galaxies at identified by the first 4 years of the JWST observations, and compare these ratios wi…
Little Red and Blue Dots: AGN-excited narrow lines, Lyman- emission, and resemblance to standard quasars
Sophia Geris, Roberto Maiolino, Xihan Ji +35
We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at , identified by JWST in the GOODS fields. While both categories are selected to ha…
JADES: the mass-metallicity relation at . New calibrations, extremely metal-poor galaxies, and chemical diversity
Yuki Isobe, Mirko Curti, Roberto Maiolino +28
We present gas-phase metallicities of star-forming galaxies at -10 with deep JWST/NIRSpec spectra from the JADES full data release, Dark Horse, and OASIS programmes. We stack…
JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5: stellar population catalogue for galaxies in GOODS-N and GOODS-S
Qiao Duan, Sandro Tacchella, Benjamin D. Johnson +37
We present the galaxy stellar population catalogue from the JWST Advanced Deep Extragalactic Survey (JADES) Data Release 5 (DR5), providing homogeneous Bayesian inference of physic…
