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…

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…

Flexible Simulation Based Inference for Galaxy Photometric Fitting with Synthesizer

Thomas Harvey, Christopher C. Lovell, Sophie Newman +13

We introduce Synference, a new, flexible Python framework for galaxy SED fitting using simulation-based inference (SBI). Synference leverages the Synthesizer package for flexible f…

Evidence of violation of Case B recombination in Little Red Dots

G. P. Nikopoulos, D. Watson, A. Sneppen +4

Little Red Dots (LRDs) are a new class of compact extragalactic objects, with a v-shaped optical spectral energy distribution breaking close to the Balmer break wavelength, and bro…
