Characterizing Lyman alpha emission from high-redshift galaxies

Samuel Gagnon-Hartman, Andrei Mesinger, Ivan Nikolić +2

The Lyman α (Lyα) line from high-redshift galaxies is a powerful probe of the Epoch of Reionization (EoR). Neutral hydrogen in the intergalactic medium (IGM) can significantly…

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…

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 (Lyα) emission in su…
