Arxiv: JWST Measurements of Neutral Hydrogen Fractions and Ionized Bubble Sizes at z=7-12 Obtained with Ly╬▒ Damping Wing Absorptions in 27 Bright Continuum Galaxies Published: 6/1/2023 12:39:03 PM Updated: 6/13/2024 8:24:28 PM

Paper abstract: We present volume-averaged neutral hydrogen fractions x_{\rm \HI} andionized bubble radii R_{\rm b} measured with Ly\alpha damping wingabsorption of galaxies at the epoch of reionization. We combine JWST/NIRSpecspectra taken by CEERS, GO-1433, DDT-2750, and JADES programs, and obtain asample containing 27 bright UV-continuum (M_{\rm UV}<-18.5~{\rm mag})galaxies at 7
