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…

Investigating black hole accretion and feedback self-regulation in Seyfert galaxies using the FIRE-3 cosmological hydrodynamic simulations

Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Jose Cevallos +12

Recent observations of local Seyfert galaxies show an intriguing connection between Active Galactic Nuclei (AGN) luminosity and a deficit of molecular gas on ~50pc scales compared…

Little Red Dots on FIRE: Exploring the formation and observational signatures of ultra-compact early galaxies

Niranjan Chandra Roy, Daniel Anglés-Alcázar, Rachel K. Cochrane +15

Little Red Dots (LRDs) are compact sources with broad Balmer lines, Balmer breaks, anomalous UV emission, rising red continuum, and uncertain origin. We use FIRE cosmological simul…

Learning the Universe at High Redshifts: Impact of Accretion Modeling on Early Black Hole Growth

Jonathan Kho, Aklant K. Bhowmick, Rainer Weinberger +8

JWST discoveries of the earliest () supermassive black holes (BHs, ) challenge the BH seeding and accretion models of most cosmol…

Learning the Universe with the 2nd Generation of CAMELS: Varying 35 parameters of the IllustrisTNG model in (50Mpc/h)^3 boxes

Shy Genel, Yongseok Jo, Boon Kiat Oh +10

We present a new set of 1,192 cosmological simulations as part of the CAMELS project, in which a space of 35 cosmological, astrophysical, and numerical parameters is explored aroun…

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…

CAMELS Environments: The Impact of Local Neighbours on Galaxy Evolution across the SIMBA, IllustrisTNG, ASTRID, and Swift-EAGLE Simulations

Xavier Sims, Daniel Anglés-Alcázar, Boon-Kiat Oh +6

Internal feedback from massive stars and active galactic nuclei (AGN) play a key role in galaxy evolution, but external environmental effects can also strongly influence galaxies.…

Cosmological back-reaction of baryons on dark matter in the CAMELS simulations

Matthew Gebhardt, Daniel Anglés-Alcázar, Shy Genel +13

Baryonic processes such as radiative cooling and feedback from massive stars and active galactic nuclei (AGN) directly redistribute baryons in the Universe but also indirectly redi…
