From ASTRID to BRAHMA -- The role of overmassive black holes in little red dots in cosmological simulations
Patrick LaChance, Aklant Kumar Bhowmick, Rupert A. C. Croft +8
We leverage the overmassive black holes () present in a realization of the BRAHMA cosmological hydrodynamic simulation suite to investigate their ro…
The abundance and properties of the lowest luminosity dwarf galaxies around the Milky Way: Insights from Semi-Analytic Models
Niusha Ahvazi, Andrew B. Pace, Christopher T. Garling +11
We investigate the formation and observable properties of faint satellite galaxies (M$_\rm V > -3$) in Milky Way-like halos using the semi-analytic galaxy formation model Galacticu…
AGN feedback in merging galaxies with a SMUGGLE multiphase ISM
Aneesh Sivasankaran, Laura Blecha, Paul Torrey +6
We study fast nuclear winds driven by Active Galactic Nucleus (AGN) feedback in merging galaxies using high-resolution hydrodynamics simulations. We use Stars and MUltiphase Gas in…
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…
Heavy seeds and the first black holes: Insights from the BRAHMA simulations
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +9
From the luminous quasars at to the recent AGNs revealed by JWST, observations of the earliest black hole (BH) populations can provide unique constraints o…
Accretion onto supermassive and intermediate mass black holes in cosmological simulations
Rainer Weinberger, Aklant Bhowmick, Laura Blecha +5
Accretion is the dominant contribution to the cosmic massive black hole density in the Universe today. Yet, modelling it in cosmological simulations is challenging due to the dynam…
