Quantifying the Effects of Known Unknowns on Inferred High-redshift Galaxy Properties: Burstiness, the IMF, and Nebular Physics

Bingjie Wang, Joel Leja, Hakim Atek +15

The era of the James Webb Space Telescope ushers stellar population models into uncharted territories, particularly at the high-redshift frontier. In a companion paper, we apply th…

Rest-Frame Near-Infrared Radial Light Profiles up to z=3 from JWST/NIRCam: Wavelength Dependence of the Sérsic Index

Marco Martorano, Arjen van der Wel, Eric F. Bell +10

We examine the wavelength dependence of radial light profiles based on Sérsic index measurements of 1067 galaxies with M 10M and in the redshift range $…

Most of the photons that reionized the Universe came from dwarf galaxies

Hakim Atek, Ivo Labbé, Lukas J. Furtak +30

The identification of sources driving cosmic reionization, a major phase transition from neutral Hydrogen to ionized plasma around 600-800 Myr after the Big Bang (Dayal et al. 2018…

UNCOVER: Illuminating the Early Universe -- JWST/NIRSpec Confirmation of Galaxies

Bingjie Wang, Seiji Fujimoto, Ivo Labbe +24

Observations of high-redshift galaxies provide a critical direct test to the theories of early galaxy formation, yet to date, only three have been spectroscopically confirmed at $z…
