Diverse Histories and Common Origins of Nitrogen-enhanced JWST Galaxies
Vadim Rusakov, Christopher J. Conselice, Thomas Harvey +2
Early JWST spectra revealed galaxies with a strong nitrogen excess challenging galactic chemical evolution models. Using public JWST surveys, we construct a sample of 76 N/O-enhanc…
Environmental dependence of the Mass-Metallicity Star Formation Relations at z=4-10 with JWST
Qiong Li, Christopher J. Conselice, Lewi Westcott +8
We study how environment affects the mass-metallicity relation (MZR) at - using deep imaging and spectroscopy from the James Webb Space Telescope (JWST). Combining CEERS a…
Reionization in Protocluster Environments at with JWST/NIRSpec
Qiong Li, Christopher J. Conselice, Duncan Austin +4
Understanding the role of high-redshift protoclusters in cosmic reionization is essential to unveiling the early stages of structure formation. Using deep imaging and spectroscopy…
Little red dots as young supermassive black holes in dense ionized cocoons
V. Rusakov, D. Watson, G. P. Nikopoulos +14
The James Webb Space Telescope (JWST) has uncovered many compact galaxies at high redshift with broad hydrogen and helium lines, including the enigmatic population of little red do…
Inside the cocoon: a comprehensive explanation of the spectra of Little Red Dots
A. Sneppen, D. Watson, J. H. Matthews +10
JWST has revealed a population of compact galaxies in the early Universe with broad emission lines and strong Balmer breaks; among them the so-called ''little red dots'' (LRDs). Th…
Resolving the ionizing photon budget crisis with JWST/NIRCam HII clumping constraints at z=6
Duncan Austin, Thomas Harvey, Christopher J. Conselice +18
We present a comprehensive study of the ionizing properties of 1721 galaxies at using deep JWST/NIRCam photometric imaging from the NEP, JADES, and PRIMER surveys spann…
