Spatially resolved gas-phase metallicity at z~2-3 with JWST/NIRISS

Ayan Acharyya, Peter J. Watson, Benedetta Vulcani +24

Spatially resolved gas-phase metallicity maps are a crucial element in understanding the chemical evolution of galaxies. We present spatially resolved metallicity maps obtained fro…

The Lyman-alpha and Continuum Origins Survey. I. Survey description and Ly imaging

Alexandra Le Reste, Claudia Scarlata, Matthew Hayes +25

Understanding the mechanisms driving the escape of ionizing or Lyman continuum (LyC) emission from the interstellar medium of galaxies is necessary to constrain the evolution of re…

Systematic Bias in Ionizing Radiation Escape Fraction Measurements from Foreground Large-Scale Structures

C. Scarlata, W. Hu, M. J. Hayes +8

We investigate the relationship between the Lyman-alpha (Lya) forest transmission in the intergalactic medium (IGM) and the environmental density of galaxies, focusing on its impli…

Joint Survey Processing. III. Compact Oddballs in the COSMOS Field -- Little Red Dots and Transients

Yu-Heng Lin, Andreas L. Faisst, Ranga-Ram Chary +7

We present the HST ACS G800L grism spectroscopy observation of the faint active galactic nuclei (AGN) candidates in the COSMOS field at redshift of 6 selected by the point-source m…

The JWST/PASSAGE Survey: Testing Reionization Histories with JWST's First Unbiased Survey for Lyman alpha Emitters at Redshifts 7.5-9.5

Axel Runnholm, Matthew J. Hayes, Vihang Mehta +25

Lyman (Ly) emission is one of few observable features of galaxies that can trace the neutral hydrogen content in the Universe during the Epoch of Reionization (EoR). To ac…
