JADES: the chemical enrichment pattern of distant galaxies -- enhancement, silicon depletion, and iron enhancement

Yuki Isobe, Roberto Maiolino, Xihan Ji +26

We present gas-phase abundances of carbon (C), -elements (O, Ne, Si, and Ar) and iron (Fe) obtained from stacked spectra of high- star-forming galaxies with the deep Near Inf…

Lord of LRDs: Insights into a "Little Red Dot" with a low-ionization spectrum at z = 0.1

Xihan Ji, Francesco D'Eugenio, Ignas Juodžbalis +14

Recent observations by the James Webb Space Telescope (JWST) have revealed a puzzling population of optically red and compact galaxies with peculiar "V"-shaped spectra at high reds…

JADES: Carbon-enhanced, Nitrogen-normal compact galaxy at z=11.2

J. Scholtz, M. S. Silcock, E. Curtis-Lake +25

Over the past few years \textit{JWST} has been a major workhorse in detecting and constraining the metal enrichment of the first galaxies in the early Universe and finding the sour…

The THESAN-ZOOM project: Mystery N/O more -- uncovering the origin of peculiar chemical abundances and a not-so-fundamental metallicity relation at

William McClymont, Sandro Tacchella, Aaron Smith +15

We present an analysis of metallicities and chemical abundances at in the THESAN-ZOOM simulations. We find that smoothly curved gas-phase and stellar mass-metallicity rela…

JADES reveals a large population of low mass black holes at high redshift

Sophia Geris, Roberto Maiolino, Yuki Isobe +24

JWST has revealed a large population of active galactic nuclei (AGN) in the distant universe, which are challenging our understanding of early massive black hole seeding and growth…

JADES and BlackTHUNDER: rest-frame Balmer-line absorption and the local environment in a Little Red Dot at z = 5

Francesco D'Eugenio, Ignas Juodžbalis, Xihan Ji +32

We present a broad-line AGN at z=5.077, observed with both NIRSpec/MSA and NIRSpec/IFU by the JADES and BlackTHUNDER surveys. The target exhibits all the hallmark features of a 'Li…
