Ly Escape in JWST/NIRCam F430M-Selected H Emitters at

Cheng Cheng, Zhen-Ya Zheng, Chunyan Jiang +8

We study the Ly escape fraction () in an H-selected sample of star-forming galaxies at , identified via JWST/NIRCam F430M excess and covered by arc…

We Must Preserve Hubble given its Unique Complementarity to Webb, Roman, and Euclid

Rogier A. Windhorst, Gibson B. Bowling, Kevin S. Croker +17

We present compelling arguments -- focusing on galaxy science -- for preserving the main imagers and operational modes of the Hubble Space Telescope (HST) for as long as is technic…

Dissecting Reionisation with the Cosmic Star Formation and Active Galactic Nuclei Luminosity History

Jordan C. J. D'Silva, Simon P. Driver, Claudia D. P. Lagos +23

The combination of the cosmic star formation history and active galactic nuclei (AGN) luminosity history as inferred by the James Webb Space Telescope is connected to th…

Globular Clusters in the Galaxy Cluster MACS0416 at z = 0.397

Jessica M. Berkheimer, Rogier A. Windhorst, William E. Harris +27

We present a photometric analysis of globular clusters (GCs) in the massive galaxy cluster MACS J0416.1-2403 (z = 0.397) using deep JWST/NIRCam imaging from the PEARLS program. PSF…

JWST's PEARLS: A Candidate Massive Binary Star System in a Lensed Galaxy at Redshift 0.94

Hayley Williams, Patrick L. Kelly, Emmanouil Zapartas +18

Massive stars at cosmological distances can be individually detected during transient microlensing events, when gravitational lensing magnifications may exceed ~1000. Nine such sou…

JWST's PEARLS: Temperatures of Nine Highly Magnified Stars in a Galaxy at Redshift 0.94 and Simulated Stellar Population Dependence on Stellar Metallicity and the Initial Mass Function

Hayley Williams, Patrick L. Kelly, Rogier A. Windhorst +17

We present stellar atmosphere modeling of JWST NIRCam photometry of nine highly magnified individual stars in a single galaxy at redshift z=0.94 known as the Warhol arc, which is s…
