The CAMELS-CROCODILE Simulation Suite: A New Cosmology--Astrophysics Playground for Machine Learning
Kentaro Nagamine, Yuri Oku, Atsushi J. Nishizawa +4
We present CAMELS-CROCODILE, a suite of cosmological hydrodynamic simulations that extends the CAMELS framework with the \gadget{} smoothed particle hydrodynamics code and the Osak…
CROCODILE-SIDM: Tidal Formation of Dark Matter-Deficient Galaxies as a Test Case
Kenji Kihara, Kentaro Nagamine, Lissandre Bourrat +3
We introduce CROCODILE-SIDM, a framework for treating self-interacting dark matter (SIDM) with the -body part of GADGET4-Osaka code, as part of CROCODILE simulation family. As a…
The AGORA High-resolution Galaxy Simulations Comparison Project. IX - Part 2: Effects of a Major Galaxy Merger on the Stellar Morphology of a Milky Way-mass Galaxy Progenitor
Thinh Huu Nguyen, Kirk S. S. Barrow, Minyong Jung +23
Galaxy mergers, with their high sensitivity to initial conditions, provide a valuable setting for comparative studies of galaxy simulation codes. Following our first paper focusing…
The AGORA High-resolution Galaxy Simulations Comparison Project. IX - Part 1: Effects of a Major Galaxy Merger on Star Formation of a Milky Way-mass Galaxy Progenitor
Thinh Huu Nguyen, Kirk S. S. Barrow, Minyong Jung +23
Given their highly nonlinear dynamics and sensitivity to initial conditions, galaxy mergers are a compelling area to conduct a simulation code comparison. We perform a comparative…
The AGORA High-resolution Galaxy Simulations Comparison Project. XI: Solving the Non-Spherical Morphology and Evolution of Dark Matter Halos with Haskap Pie
Kirk S. S. Barrow, Thinh Huu Nguyen, Santi Roca-Fàbrega +26
We introduce a halo solving and tracking procedure that intrinsically treats dark matter halos as non-spherical objects by leveraging the bound particle searching techniques used i…
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…
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…
Observational signatures of the dust size evolution in isolated galaxy simulations
Kosei Matsumoto, Hiroyuki Hirashita, Kentaro Nagamine +9
We aim to provide observational signatures of the dust size evolution in the ISM. In particular, we explore indicators of the polycyclic aromatic hydrocarbon (PAH) mass fraction ($…
Osaka Feedback Model III: Cosmological Simulation CROCODILE
Yuri Oku, Kentaro Nagamine
We introduce our new cosmological simulation dataset CROCODILE, executed using the GADGET4-Osaka smoothed particle hydrodynamics code. This simulation incorporates an updated super…
Osaka Feedback Model II: Modeling Supernova Feedback Based on High-Resolution Simulations
Yuri Oku, Kengo Tomida, Kentaro Nagamine +2
Feedback from supernovae (SNe) is an essential mechanism that self-regulates the growth of galaxies, and a better model of SN feedback is still needed in galaxy formation simulatio…
