The Prevalence of Bursty Star Formation in Low-Mass Galaxies at z=1-7 from Hα-to-UV Diagnostics

Marissa N. Perry, Anthony J. Taylor, Oscar A. Chavez Ortiz +15

We present an analysis of bursty star-formation histories (SFHs) of 346 star-forming galaxies at , selected from JWST/NIRSpec G395M and PRISM spectroscopy provided b…

Ly visibility from z = 4.5 to 11 in the UDS field: Evidence for a high neutral hydrogen fraction and small ionized bubbles at z 7

L. Napolitano, L. Pentericci, M. Dickinson +28

The resonant scattering nature of Ly photons interacting with neutral hydrogen makes Ly emitters (LAEs) robust tracers of the intergalactic neutral hydrogen fraction, and thu…

Testing Photometric Techniques for Measuring the Rest-Frame UV Spectral Slope Against JWST PRISM Spectroscopy

Alexa M. Morales, Steven L. Finkelstein, Pablo Arrabal Haro +21

We present a sample of 53 galaxy spectra at z_spec ~ 5-12 from the JWST CEERS and RUBIES surveys, combining NIRSpec PRISM spectroscopy with NIRCam photometry. We aim to use these d…

Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions

Casey Papovich, Justin W. Cole, Weida Hu +27

Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…

CAPERS Observations of Two UV-Bright Galaxies at z>10. More Evidence for Bursting Star Formation in the Early Universe

Vasily Kokorev, Óscar A. Chávez Ortiz, Anthony J. Taylor +38

We present the first results from the CAPERS survey, utilizing PRISM observations with the JWST/NIRSpec MSA in the PRIMER-UDS field. With just 14 % of the total planned data volume…
