Toward a Multimodal Foundation Model for Plasma State Reconstruction
Bin Xia, Chuanfei Dong, Boting Li +9
Plasma experiments observe coupled physical states through sparse, heterogeneous, and incomplete diagnostics. We present a proof of concept toward a multimodal foundation model for…
Three-dimensional Conditional Diffusion Models for Cosmological 21 cm Lightcone Emulation
Bin Xia, John H. Wise
We investigate conditional diffusion modeling for three-dimensional 21 cm lightcone emulation, focusing on cubes with a sky-plane size of and a line-of-sight depth up…
QuaRT: A toolkit for the exploration of quantum methods for radiation transport
Rasmit Devkota, John H. Wise
QuaRT is a Python library for quantum simulation of radiative transfer in astrophysical and cosmological problems. It features a novel angular redistribution methodology for lattic…
Identification of Candidate Halos Hosting Massive Black Hole Seeds in the Simulations with Support Vector Machines
Brandon Pries, John H. Wise
The nature of the origins of supermassive black holes remains uncertain. Multiple possible seeding pathways have been proposed across a variety of mass scales, each with their own…
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…
Multi-modal Foundation Model for Cosmological Simulation Data
Bin Xia, Nesar Ramachandra, Azton I. Wells +2
We present a multi-modal foundation model for astrophysical galaxy data, designed to map between simulation- and observation-based galactic features. Our encoder-only transformer f…
Aeos is Mixing it Up: The (In)homogeneity of Metal Mixing Following Population III Star Formation
Jennifer Mead, Kaley Brauer, Greg L. Bryan +7
Stellar surface abundances are records of the state of the gas from which stars formed, and thus trace how individual elements have mixed into the surrounding medium following thei…
Aeos: The Impact of Population III Initial Mass Function and Star-by-Star Models in Galaxy Simulations
Kaley Brauer, Jennifer Mead, John H. Wise +7
We explore the effect of variations in the Population III (Pop III) initial mass function (IMF) and star-by-star feedback on early galaxy formation and evolution using the Aeos sim…
Aeos: Transport of Metals from Minihalos following Population III Stellar Feedback
Jennifer Mead, Kaley Brauer, Greg L. Bryan +7
We investigate how stellar feedback from the first stars (Population III) distributes metals through the interstellar and intergalactic medium using the star-by-star cosmological h…
AEOS: Star-by-Star Cosmological Simulations of Early Chemical Enrichment and Galaxy Formation
Kaley Brauer, Andrew Emerick, Jennifer Mead +7
The AEOS project introduces a series of high-resolution cosmological simulations that model star-by-star chemical enrichment and galaxy formation in the early Universe, achieving 1…
A Framework to Calibrate a Semi-analytic Model of the First Stars and Galaxies to the Renaissance Simulations
Ryan Hazlett, Mihir Kulkarni, Eli Visbal +1
We present a method that calibrates a semi-analytic model to the Renaissance Simulations, a suite of cosmological hydrodynamical simulations with high-redshift galaxy formation. Th…
