diffhydro: Inverse Multiphysics Modeling and Embedded Machine Learning in Astrophysical Flows
Benjamin Horowitz, Zarija Lukić, Kentaro Nagamine +1
We present the extension of the differentiable hydrodynamics code, diffhydro, enabling scalable PDE-constrained inference and integrated hybrid physics-ML models for a wide range o…
Cosmic Himalayas in CROCODILE : Probing the Extreme Quasar Overdensities by Count-in-Cells analysis and Nearest Neighbor Distribution
Yuto Kuwayama, Yongming Liang, Kentaro Nagamine +7
The recently reported Cosmic Himalayas (CH) -- an extreme quasar overdensity at z~2 -- poses an apparent challenge to the Lambda CDM framework, with a reported significance of 16.9…
Validating the CROCODILE model within the AGORA galaxy simulation framework
Pablo Granizo, Yuri Oku, Kentaro Nagamine
Numerical galaxy formation simulations are sensitive to numerical methods and sub-grid physics models, making code comparison projects essential for quantifying uncertainties. Here…
Recombination Clumping Factor of Physically Defined Intergalactic Medium at the Epoch of Reionization
Yuri Oku, Renyue Cen
The recombination clumping factor, , is a key parameter in modeling cosmic reionization, but its value is sensitive to the definition of the Intergalactic Medium (IGM). We inves…
The AGORA High-resolution Galaxy Simulations Comparison Project. X: Formation and Evolution of Galaxies at the High-redshift Frontier
Hyeonyong Kim, Ji-hoon Kim, Minyong Jung +22
Recent observations from JWST have revealed unexpectedly luminous galaxies, exhibiting stellar masses and luminosities significantly higher than predicted by theoretical models at…
CROCODILE-DWARF: Assembly and Kinematics of Field Dwarf Galaxies with GADGET4-OSAKA
Kazuki Tomaru, Yuri Oku, Daisuke Toyouchi +1
We present results from CROCODILE-DWARF, a new suite of cosmological zoom-in hydrodynamic simulations of isolated field dwarf galaxies with halo masses of at…
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…
The AGORA High-resolution Galaxy Simulations Comparison Project. VIII: Disk Formation and Evolution of Simulated Milky Way Mass Galaxy Progenitors at
Minyong Jung, Ji-hoon Kim, Thinh H. Nguyen +24
We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 , using eight state-of-the-art…
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…
