JWST NIRCam Photometry: A Study of Globular Clusters Surrounding Bright Elliptical Galaxy VV 191a at z=0.0513

Jessica M. Berkheimer, Timothy Carleton, Rogier A. Windhorst +22

James Webb Space Telescope NIRCam images have revealed 154 reliable globular cluster (GC) candidates around the elliptical galaxy VV~191a after subtracting 34 likely i…

Star formation and AGN activity 500 Myr after the Big Bang: Insights from JWST

Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +3

We consider the effect of including an active galactic nuclei (AGN) component when fitting spectral energy distributions of 109 spectroscopically confirmed gala…

Magellanic System Stars Identified in SMACS J0723.3-7327 James Webb Space Telescope Early Release Observations Images

Jake Summers, Rogier A. Windhorst, Seth H. Cohen +23

We identify 71 distant stars in JWST/NIRCam ERO images of the field of galaxy cluster SMACS J0723.3-7327 (SMACS 0723). Given the relatively small () angular separ…

EPOCHS Paper II: The Ultraviolet Luminosity Function from using 180 square arcminutes of deep, blank-fields from the PEARLS Survey and Public JWST data

Nathan J. Adams, Christopher J. Conselice, Duncan Austin +34

We present an analysis of the ultraviolet luminosity function (UV LF) and star formation rate density of distant galaxies () in the `blank' fields of the Prime Extr…

Are JWST/NIRCam color gradients in the lensed z=2.3 dusty star-forming galaxy El Anzuelo due to central dust attenuation or inside-out galaxy growth?

Patrick S. Kamieneski, Brenda L. Frye, Massimo Pascale +24

Gradients in the mass-to-light ratio of distant galaxies impede our ability to characterize their size and compactness. The long-wavelength filters of 's NIRCam offer a signi…
