On Cross-Correlating Line Intensity Maps from SPHEREx during Reionization
Abigail E. Ambrose, Eli Visbal, Matthew McQuinn
We have simulated Lyα, Hα, Hβ, [OII], and [OIII] intensity maps which are observable by SPHEREx during cosmic reionization. We simulate these intensity maps including all signif…
Chemical Signatures of Population III Stars in Damped Lyman- Absorption Systems at
Eli Visbal, Greg L. Bryan, Zoltan Haiman
Recently, Sodini et al. (2024) presented a sample of OI damped Lyman- absorption system (DLA) analogs at that contain possible chemical signatures of Population III (P…
LAP1-B is the First Observed System Consistent with Theoretical Predictions for Population III Stars
Eli Visbal, Ryan Hazlett, Greg L. Bryan
Recently, Nakajima et al. (2025) presented James Webb Space Telescope observations of the Population III (Pop III) candidate LAP1-B, which is gravitationally lensed by gala…
From Primordial Stars to Early Galaxies: A Semi-Analytic Model Calibrated with Aeos and Renaissance
Ryan Hazlett, Jennifer Mead, Eli Visbal +6
We present an extension of our semi-analytic model that follows the formation of Population III stars and their metal-enriched descendants, incorporating dark matter halo merger tr…
Evaluating the Accuracy of Reionization Prescriptions in Semi-analytic Models of the First Stars and Galaxies
Thomas Behling, Ryan Hazlett, Mihir Kulkarni +1
Semi-analytic models are a valuable tool to study the first stars and galaxies. Their numerical efficiency makes it possible to survey broad regions of astrophysical parameter spac…
Radiative Transfer Simulations of Ly Intensity Mapping During Cosmic Reionization Including Sources from Galaxies and the Intergalactic Medium
Abigail E. Ambrose, Eli Visbal, Mihir Kulkarni +1
We present new simulations of Lyman- (Ly) intensity maps that include Ly radiative transfer in the intergalactic medium (IGM) and all significant sources of Ly phot…
