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…
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…
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…
Cosmic Rays in Galaxy Halos: Impacts on Galactic Outflows and Baryon Cycling
Ellis R. Owen, Leonard E. C. Romano, Kentaro Nagamine
Galaxies with high star-formation rate surface densities often host large-scale outflows that redistribute energy, momentum, and baryons between the interstellar medium and the hal…
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…
Evolution of galaxy attenuation curves driven by evolving dust mass and grain size distributions
Kosei Matsumoto, Laura Sommovigo, Andrea Gebek +8
We investigate the impacts of the evolution of dust mass and grain size distribution within a Milky Way-like (MW-like) galaxy simulation on global attenuation curves, focusing on t…
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…
Starburst-Driven Galactic Outflows -- Unveiling the Suppressive Role of Cosmic Ray Halos
Leonard E. C. Romano, Ellis R. Owen, Kentaro Nagamine
Aims. We investigate the role of cosmic ray (CR) halos in shaping the properties of starburst-driven galactic outflows. Methods. We develop a microphysical model for galactic outfl…
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…
