Exploring the High-Redshift 21-cm Signal via Self-Consistent Simulations using Artificial Neural Network Emulation
Colton R. Feathers, Eli Visbal, Steven Murray +2
We present a novel, self-consistent, semi-numeric Cosmic Dawn (CD) simulation in which small-scale star formation (SF) is calibrated to the \emph{AEOS} and \emph{Renaissance} hydro…

From Dark Matter Minihalos to Large-Scale Radiative Feedback: A Self-Consistent 3D Simulation of the First Stars and Galaxies using Neural Networks
Colton Feathers, Mihir Kulkarni, Eli Visbal
A key obstacle to accurate models of the first stars and galaxies is the vast range of distance scales that must be considered. While star formation occurs on sub-parsec scales wit…

A Global Semi-Analytic Model of the First Stars and Galaxies Including Dark Matter Halo Merger Histories
Colton R. Feathers, Mihir Kulkarni, Eli Visbal +1
We present a new self-consistent semi-analytic model of the first stars and galaxies to explore the high-redshift () Population III (PopIII) and metal-enriched star formati…
