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…
AGN jet evolution simulation with GADGET4-OSAKA
Chenze Dong, Abednego Wiliardy, Kentaro Nagamine +4
Active galactic nuclei (AGN) jets are powerful drivers of galaxy evolution, depositing energy and momentum into the circumgalactic and intracluster medium (CGM/ICM) and regulating…
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…
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…
