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…
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…
Applying a star formation model calibrated on high-resolution interstellar medium simulations to cosmological simulations of galaxy formation
Jan D. Burger, Volker Springel, Eve C. Ostriker +11
Modern high-resolution simulations of the interstellar medium (ISM) have shown that key factors in governing star formation are the competing influences of radiative dissipation, p…
Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations
Aklant K Bhowmick, Laura Blecha, Paul Torrey +8
The first "seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle, and it is currently unclear whether the imprints of early seed formation survive today. He…
