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}…
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…
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…
