Constraints on the intergalactic medium from JWST spectroscopy of Lyman-alpha damping wings in galaxies

Charlotte A. Mason, Zuyi Chen, Daniel P. Stark +3

JWST provides a unique dataset to study reionization's earliest stages, promising insights into the first galaxies. Many JWST/NIRSpec prism spectra reveal smooth Lyman-alpha breaks…

Deep JWST spectroscopy of galaxies in a candidate ionized bubble at : probing reionization at pMpc scales with Ly emission

Lily Whitler, Daniel P. Stark, Charlotte A. Mason +5

Strong Ly emission observed from galaxies when the Universe is expected to be highly neutral is thought to trace large ionized regions that facilitate the transmission of Ly$α…

Mapping reionization bubbles in the JWST era II: inferring the position and characteristic size of individual bubbles

Ivan Nikolić, Andrei Mesinger, Charlotte A. Mason +5

The James Webb Space Telescope (JWST) is discovering an increasing number of galaxies well into the early stages of the Epoch of Reionization (EoR). Many of these galaxies are clus…

The Impact of Galaxy Overdensities and Ionized Bubbles on Ly Emission at

Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +4

Ly spectroscopy with JWST is opening a new window on the sizes of ionized bubbles through the reionization epoch. Theoretical expectations suggest typical bubble radii should b…

Mapping reionization bubbles in the JWST era I: empirical edge detection with Lyman alpha emission from galaxies

Ting-Yi Lu, Charlotte A. Mason, Andrei Mesinger +7

Ionized bubble sizes during reionization trace physical properties of the first galaxies. JWST's ability to spectroscopically confirm and measure Lyman-alpha (Ly) emission in s…
