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…

Paper 1: The JWST PEARLS View of the El Gordo Galaxy Cluster and of the Structure It Magnifies

Brenda L. Frye, Massimo Pascale, Nicholas Foo +41

The massive galaxy cluster El Gordo (z=0.87) imprints multitudes of gravitationally lensed arcs onto James Webb Space Telescope (JWST) Near-Infrared Camera (NIRCam) images. Eight b…

EPOCHS IX. When cosmic dawn breaks: Evidence for evolved stellar populations in galaxies from PEARLS GTO and public NIRCam imaging

James A. A. Trussler, Christopher J. Conselice, Nathan Adams +28

The presence of evolved stars in high-redshift galaxies can place valuable indirect constraints on the onset of star formation in the Universe. Thus we use PEARLS GTO and public NI…
