Supermassive Black Hole Assembly from Heavy Seeds with Dynamical Friction in the BRAHMA Simulations: Implications for JWST, LISA, and the Local Universe
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +8
The JWST discoveries of supermassive black holes (BHs) at may provide key insights into their seeding origins. Using new BRAHMA cosmological sim…
ArkenstoneBH. A model for high-specific energy black hole feedback in cosmological simulations
James M. Sullivan, Greg L. Bryan, Matthew C. Smith +6
AGN feedback is a key piece of galaxy evolution but is difficult to model due to its high specific energies, multiphase nature, and limited simulation resolutions. Arkenstone is a…
The Cosmic Baryon Cycle in IllustrisTNG: flows of mass, energy, and metals
Yossi Oren, Viraj Pandya, Rachel S. Somerville +3
We measure and analyze the inflows and outflows of mass, energy, and metals through the interstellar medium (ISM) and circumgalactic medium (CGM) of galaxies in the IllustrisTNG100…
A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn
Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42
We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…
Blue Monsters and Dusty Descendants: Reconciling UV and IR Emission from Galaxies from z=7, up to z= 14
Laura Sommovigo, Lachlan Lancaster, Shyam H. Menon +3
Recent JWST observations reveal massive, UV-bright galaxies at with little apparent dust attenuation, whereas ALMA detections at show similarly massive system…
MISTRAL: a model for AGN winds from radiatively efficient accretion in cosmological simulations
Marion Farcy, Michaela Hirschmann, Rachel S. Somerville +11
Feedback from active galactic nuclei (AGN) is crucial for regulating galaxy evolution. Motivated by observations of broad absorption line winds from rapidly accreting supermassive…
