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…
A steep mass transition for bar-driven ISM structuring revealed by PHANGS-JWST
Eric Emsellem, Jessica Sutter, Ryan Chown +26
Galactic bars play a critical role in the secular evolution of their hosts by reorganising the ISM. We use a sample of 57 star-forming disc galaxies observed with JWST at 3 and 7.7…
A stellar bar hidden in an extreme gas-rich disk galaxy at z=4.055
Leindert A. Boogaard, Luca Costantin, Thor Tepper-GarcÃa +14
The classical picture for the formation of stellar bars -- key dynamical drivers of the evolution of galaxies -- is through secular evolution of instability in gas poor, stellar-do…
Enhanced rates of stellar radial migration in gas-rich discs at high redshift
HanYuan Zhang, Thor Tepper-GarcÃa, Vasily Belokurov +6
Radial migration and dynamical heating redistribute stars within galactic discs and thereby modify the chemo-kinematic structure of their host galaxies. Usually, these secular proc…
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-FÃ brega +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…
