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…

A Rapid Evolution in the Observed Mbh/M* Relation at z > 3 Revealed via Spectro-photometric SED-Modeling

Ansh R. Gupta, Anthony Taylor, Emma Curtis-Lake +33

Spectroscopic observations from JWST have uncovered a plethora of active galactic nuclei (AGN) at z > 4 with black hole (BH) mass (Mbh) to stellar mass (M*) ratios significantly ab…

JADES: Evolution of nitrogen abundances in star-forming galaxies from z ~ 1.5-7

Alex J. Cameron, Courtney Carreira, Charlotte Simmonds +22

We present nitrogen abundance measurements based on the low-ionisation [NII]6583 emission line for 588 galaxies between 1.5<z<7.0 from the JWST Advanced Deep Extragalactic Survey (…

Overview of the JWST Advanced Deep Extragalactic Survey (JADES)

Daniel J. Eisenstein, Chris Willott, Stacey Alberts +75

We present an overview of the James Webb Space Telescope (JWST) Advanced Deep Extragalactic Survey (JADES), an ambitious program of infrared imaging and spectroscopy in the GOODS-S…

Significant Evidence of an AGN Contribution in GHZ2 at z = 12.34

Oscar A. Chavez Ortiz, Steven L. Finkelstein, Adele Plat +19

GHZ2 is among the highest-redshift galaxies discovered to date, exhibiting a spectrum rich with prominent emission lines in the rest-frame ultraviolet (UV) and optical. These featu…

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…
