Constraining reionization with persistent homology: a novel summary statistic for wide-field Lyman- emitter observations

Michael M. Wyatt, Nikolaos Triantafyllou, Steven R. Furlanetto +4

The spatial clustering of Lyman- emitters (LAEs) is one of the most promising observables for constraining reionization. In this work, we introduce persistent homology, a popula…

TILING I: Field-level Bayesian reconstruction of cosmological initial conditions during the epoch of reionization

Nikolaos Triantafyllou, Andrei Mesinger, Steven Murray +1

Reconstructing the initial conditions (ICs) of the matter field for an observed volume gives a complete picture of that region's temporal evolution. IC reconstruction is common at…

Square Kilometer Array Synergies for the Epoch of Reionization and Cosmic Dawn

Anirban Chakraborty, Tirthankar R. Choudhury, Kanan K. Datta +15

Synergies with other instruments will be essential in making, verifying, and interpreting a detection of the cosmic 21-cm signal from the Epoch of Reionization (EoR) and Cosmic Daw…

Characterizing Lyman alpha emission from high-redshift galaxies

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

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

SKA-ESO Synergies for the Epoch of Reionization and Cosmic Dawn

Andrei Mesinger, Benedetta Ciardi, James E. Davies +2

Mapping out the first billion years using the 21-cm line with the Square Kilometer Array (SKA) will revolutionize our understanding of the cosmic dawn, reionization and the galaxie…

Detecting galaxy-21-cm cross-correlation during reionization

Samuel Gagnon-Hartman, James E. Davies, Andrei Mesinger

The cosmic 21-cm signal promises to revolutionize studies of the Epoch of Reionization (EoR). Radio interferometers are aiming for a preliminary, low signal-to-noise (S/N) detectio…

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 (Ly) emission in su…
