Growth of high redshift supermassive black holes from heavy seeds in the BRAHMA cosmological simulations: Implications of overmassive black holes
Aklant K Bhowmick, Laura Blecha, Paul Torrey +6
JWST has recently revealed a large population of accreting black holes (BHs) in the early Universe. Even after accounting for possible systematic biases, the high-z $M_*-M_{\rm \rm…
Signatures of Circumbinary Disk Dynamics in Multi-Messenger Population Studies of Massive Black Hole Binaries
Magdalena Siwek, Luke Zoltan Kelley, Lars Hernquist
We investigate the effect of cutting-edge circumbinary disk (CBD) evolution models on massive black hole binary (MBHB) populations and the gravitational wave background (GWB). We s…
AGN feedback in isolated galaxies with a SMUGGLE multiphase ISM
Aneesh Sivasankaran, Laura Blecha, Paul Torrey +6
Feedback from active galactic nuclei (AGN) can strongly impact the host galaxies by driving high-velocity winds that impart substantial energy and momentum to the interstellar medi…
Introducing the BRAHMA simulation suite: Signatures of low mass black hole seeding models in cosmological simulations
Aklant K. Bhowmick, Laura Blecha, Paul Torrey +6
The first "seeds" of supermassive black holes (BH) can range from . However, the lowest mass seeds () are inaccessible to most cosm…
Representing low mass black hole seeds in cosmological simulations: A new sub-grid stochastic seed model
Aklant K Bhowmick, Laura Blecha, Paul Torrey +5
The nature of the first seeds of supermassive black holes (SMBHs) is currently unknown, with postulated initial masses ranging from to as low as $\sim10^2~M_{\…
The NANOGrav 15-year Data Set: Constraints on Supermassive Black Hole Binaries from the Gravitational Wave Background
Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +111
The NANOGrav 15-year data set shows evidence for the presence of a low-frequency gravitational-wave background (GWB). While many physical processes can source such low-frequency gr…
