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…

Percent-level timing of reionization: self-consistent, implicit-likelihood inference from XQR-30+ Ly forest data

Yuxiang Qin, Andrei Mesinger, David Prelogović +13

The Lyman alpha (Lya) forest in the spectra of z>5 quasars provides a powerful probe of the late stages of the Epoch of Reionization (EoR). With the recent advent of exquisite data…

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…

The importance of stochasticity in determining galaxy emissivities and UV LFs during cosmic dawn and reionization

Ivan Nikolić, Andrei Mesinger, James E. Davies +1

The stochastic nature of star formation and photon propagation in high-redshift galaxies can result in sizable galaxy-to-galaxy scatter in their properties. Ignoring this scatter b…

How informative are summaries of the cosmic 21-cm signal?

David Prelogović, Andrei Mesinger

The cosmic 21-cm signal will bring data-driven advances to studies of the Cosmic Dawn (CD) and Epoch of Reionization (EoR). Radio telescopes such as the SKA will eventually map the…
