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…
The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries
David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67
In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…
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…
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…
Central Cluster Galaxies: A Hotspot for Detectable Gravitational Waves from Black Hole Mergers
Yihao Zhou, Tiziana Di Matteo, Nianyi Chen +6
After Pulsar Timing Arrays (PTAs) have announced the evidence for a low-frequency gravitational wave background (GWB), the continuous waves (CWs) are the next anticipated gravitati…
Dynamics of low-mass black hole seeds in the BRAHMA simulations using subgrid-dynamical friction: Impact on merger-driven black hole growth in the high redshift Universe
Aklant K. Bhowmick, Laura Blecha, Luke Z. Kelley +7
We analyze the dynamics of low-mass black hole (BH) seeds in the high-redshift () Universe using a suite of and BRAHMA cosmol…
