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 1≲z<7, selected from JWST/NIRSpec G395M and PRISM spectroscopy provided b…

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…

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…
