21 Balmer Jump Street: The Nebular Continuum at High Redshift and Implications for the Bright Galaxy Problem, UV Continuum Slopes, and Early Stellar Populations

Harley Katz, Alex J. Cameron, Aayush Saxena +11

We study the physical origin and spectroscopic impact of extreme nebular emission in high-redshift galaxies. The nebular continuum, which can appear during an extreme starburst, is…

Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe

Callum Witten, William McClymont, Nicolas Laporte +12

While JWST has observed galaxies assembling as early as , evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) -- the descendan…

JWST, ALMA, and Keck Spectroscopic Constraints on the UV Luminosity Functions at z~7-14: Clumpiness and Compactness of the Brightest Galaxies in the Early Universe

Yuichi Harikane, Akio K. Inoue, Richard S. Ellis +33

We present the number densities and physical properties of the bright galaxies spectroscopically confirmed at . Our sample is composed of 60 galaxies at $z_\mathrm{spec}…

Chemical Abundances of Early Quiescent Galaxies: New Observations and Modelling Impacts

Marziye Jafariyazani, Andrew B. Newman, Bahram Mobasher +3

Recent stellar chemical abundance measurements of a handful of quiescent galaxies have suggested these galaxies exhibit a remarkably strong -enhancement compared to the…

Glimmers in the Cosmic Dawn: A Census of the Youngest Supermassive Black Holes by Photometric Variability

Matthew J. Hayes, Jonathan C. Tan, Richard S. Ellis +10

We report first results from a deep near infrared campaign with the Hubble Space Telescope to obtain late-epoch images of the Hubble Ultra-Deep Field (HUDF), 10-15 years after the…
