Abundant Heavy Black Hole Seeds from Moderate Lyman-Werner Radiation
Ryan Hazlett, Eli Visbal, Greg L. Bryan +1
The existence of high-redshift quasars may indicate that massive black hole seeds formed via supermassive Population III stars in atomic-cooling halos with large gas inflow rates;…
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 photons.…
Can supermassive stars form in protogalaxies due to internal Lyman-Werner feedback?
James Sullivan, Zoltan Haiman, Mihir Kulkarni +1
Population III stars are possible precursors to early massive and supermassive black holes (BHs). The presence of soft UV Lyman Werner (LW) background radiation can suppress Popula…
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 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…
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…
A universal equation to predict from halo and galaxy catalogues
Helen Shao, Natalí S. M de Santi, Francisco Villaescusa-Navarro +13
We discover analytic equations that can infer the value of from the positions and velocity moduli of halo and galaxy catalogues. The equations are derived by combining…
If dark matter is fuzzy, the first stars form in massive pancakes
Mihir Kulkarni, Eli Visbal, Greg L. Bryan +1
Fuzzy dark matter (FDM) is a proposed modification for the standard cold dark matter (CDM) model motivated by small-scale discrepancies in low-mass galaxies. Composed of ultra-ligh…
Robust field-level inference with dark matter halos
Helen Shao, Francisco Villaescusa-Navarro, Pablo Villanueva-Domingo +13
We train graph neural networks on halo catalogues from Gadget N-body simulations to perform field-level likelihood-free inference of cosmological parameters. The catalogues contain…
What is the Halo Mass Function in a Fuzzy Dark Matter Cosmology?
Mihir Kulkarni, Jeremiah P. Ostriker
Fuzzy dark matter (FDM) or wave dark matter is an alternative theory designed to solve the small-scale problems faced by the standard cold dark matter proposal for the primary mate…
The critical dark matter halo mass for Population III star formation: dependence on Lyman-Werner radiation, baryon-dark matter streaming velocity, and redshift
Mihir Kulkarni, Eli Visbal, Greg L. Bryan
A critical dark matter halo mass () for Population III (Pop III) stars can be defined as the typical minimum halo mass that hosts sufficient cold dense gas required f…
Fragmentation in Population III Galaxies formed through Ionizing Radiation
Mihir Kulkarni, Eli Visbal, Greg L. Bryan
Population III stars forming in minihalos tend to be relatively inefficient, with each minihalo hosting one or a small number of stars which are more massive than local stars but s…
Preparing for advanced LIGO: A Star-Galaxy Separation Catalog for the Palomar Transient Factory
A. A. Miller, M. K. Kulkarni, Y. Cao +3
The search for fast optical transients, such as the expected electromagnetic counterparts to binary neutron star mergers, is riddled with false positives ranging from asteroids to…
