PIFFLE: Characterizing the Foreground Contributions from 4 Decades in Halo Mass to the FRB20230907D Dispersion Measure
Qi Guo, Khee-Gan Lee, Sunil Simha +10
We characterize the foreground environment of FRB20230907D, localized to a galaxy at , which has an observed dispersion measure of ${\rm DM}_{\rm obs}=1031~{\rm pc~cm^{-3}…
A Decade to Map the Diffuse Universe: FRB-QSO Pairs with HST/COS Spectroscopy
Jessica Werk, Matthew McQuinn, J. Xavier Prochaska +16
Jointly analyzing the sightlines of arcsecond-localized fast radio bursts (FRBs) and UV-bright quasars (QSOs) nearby in projection has the potential to provide strong constraints o…
MujicΛ: Reconstructing Initial Conditions from Incomplete Redshift Surveys with Projected Optimization
Chenze Dong, Benjamin Horowitz, Adrian E. Bayer +1
In this paper, we introduce MujicΛ (Mapping the Universe with Jax-based Initial Condition ReconstrΛction), an optimization-based framework for reconstructing initial conditions fro…
HaloFlow II: Robust Galaxy Halo Mass Inference with Domain Adaptation
Nikhil Garuda, ChangHoon Hahn, Connor Bottrell +1
Precise halo mass () measurements are crucial for cosmology and galaxy formation. HaloFlow introduced a simulation-based inference (SBI) framework that uses state-of-the-art s…
Magnetic fields in galactic environments probed by Fast Radio Bursts
Ilya S. Khrykin, Nicolas Tejos, J. Xavier Prochaska +7
FRBs constitute a unique probe of various astrophysical and cosmological environments via their characteristic dispersion and rotation (RM) measures that encode information about t…
Simba Simulation: The Effect of Feedback Physics on Matter Distribution in the Cosmic Web
Chenze Dong, Florian Dedieu, Daniela Galárraga-Espinosa +3
The discrepancy between the early-time estimation and late-time observation on the cosmic baryon content - the 'missing baryon problem' - is a longstanding problem in cosmology. Al…
Probing the Cosmic Baryon Distribution and the Impact of Active Galactic Nuclei Feedback with Fast Radio Bursts in CROCODILE Simulation
Zhao Joseph Zhang, Kentaro Nagamine, Yuri Oku +6
We investigate the Missing Baryon problem using Fast Radio Bursts (FRBs) to trace cosmic baryons. Our CROCODILE simulations, performed with the GADGET3/4-OSAKA smoothed particle hy…
A Neural Network Model for the Cosmic Dispersion Measure in the CAMELS Simulations
Qi Guo, Khee-Gan Lee
The probability distribution, of cosmic dispersion measures (DM) measured in fast radio bursts (FRBs) encodes information about both cosmology and galaxy feedback.…
Modeling the Cosmic Dispersion Measure in the D < 120 Mpc Local Universe
Yuxin Huang, Khee-Gan Lee, Noam I. Libeskind +3
The Local Universe (D < 120 Mpc) has been intensely studied for decades, with highly complete galaxy redshift surveys now publicly available. These data have driven density reconst…
Cosmology with Fast Radio Bursts
Marcin Glowacki, Khee-Gan Lee
Despite the first detection of fast radio bursts (FRBs) being as recent as 2007, they have already been proven to be a fantastic tool as a unique cosmological probe. In this chapte…
Introducing cosmosTNG: simulating galaxy formation with constrained realizations of the COSMOS field
Chris Byrohl, Dylan Nelson, Benjamin Horowitz +2
We introduce the new cosmological simulation project cosmosTNG, a first-of-its-kind suite of constrained galaxy formation simulations for the universe at Cosmic Noon (). c…
The Effect of AGN Feedback on the Lyman-α Forest Signature of Galaxy Protoclusters at z~2.3
Chenze Dong, Khee-Gan Lee, Romeel Davé +2
The intergalactic medium (IGM) in the vicinity of galaxy protoclusters are interesting testbeds to study complex baryonic effects such as gravitational shocks and feedback. Here, w…
I: Neural Inference of Halo Mass from Galaxy Photometry and Morphology
ChangHoon Hahn, Connor Bottrell, Khee-Gan Lee
We present , a new machine learning approach for inferring the mass of host dark matter halos, , from the photometry and morphology…
