EIGER VIII: First stars signatures in the connection between OI absorption and Galaxies in the Epoch of Reionization

Jack Higginson, Rongmon Bordoloi, Robert A. Simcoe +8

We investigate the association between galaxies and neutral OI absorption systems at z~6, which trace metal-enriched gas during the epoch of reionization. We identify 40 galaxies a…

A PAH deficit in the starburst core of a distant spiral galaxy

Zhaoxuan Liu, John D. Silverman, Emanuele Daddi +32

We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at . The NIRCam observations mainly trace the stellar ligh…
