AGN Line-Intensity Mapping: A Probe of Faint Black Holes at Cosmic Noon
Eli Visbal, Greg L. Bryan
We propose line-intensity mapping (LIM) as a new probe of active galactic nuclei (AGN). By cross-correlating [Ne V] intensity maps with galaxy redshift surveys, we show that the cu…
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…
Field-Level Comparison and Robustness Analysis of Cosmological N-body Simulations
Adrian E. Bayer, Francisco Villaescusa-Navarro, Sammy Sharief +6
We present the first field-level comparison of cosmological N-body simulations, considering various widely used codes: Abacus, CUBEPM, Enzo, Gadget, Gizmo, PKDGrav, and Ramses.…
Predicting the number density of heavy seed massive black holes due to an intense Lyman-Werner field
Hannah O'Brennan, John A. Regan, John Brennan +5
The recent detections of a large number of candidate active galactic nuclei at high redshift (i.e. ) has increased speculation that heavy seed massive black hole forma…
Quantifying Lyman- emissions from reionization fronts
Bayu Wilson, Anson D'Aloisio, Christopher Cain +2
During reionization, intergalactic ionization fronts (I-fronts) are sources of Ly line radiation produced by collisional excitation of hydrogen atoms within the fronts. In prin…
