Supermassive black hole growth in hierarchically merging nuclear star clusters
Konstantinos Kritos, Ricarda S. Beckmann, Joseph Silk +5
Supermassive black holes are prevalent at the centers of massive galaxies, and their masses scale with galaxy properties, increasing evidence suggesting that these trends continue…
Wandering and escaping: recoiling massive black holes in cosmological simulations
Chi An Dong-Páez, Marta Volonteri, Yohan Dubois +2
After a merger of two massive black holes (MBHs), the remnant receives a gravitational wave (GW) recoil kick that can have a strong effect on its future evolution. The magnitude of…
Conditions for Super-Eddington Accretion onto the First Black Holes
Simone T. Gordon, Britton D. Smith, Sadegh Khochfar +1
Observations of supermassive black holes at high redshift challenge our understanding of the evolution of the first generation of black holes (BHs) in proto-galactic environments.…
Black hole spin evolution across cosmic time from the NewHorizon simulation
Ricarda S. Beckmann, Yohan Dubois, Marta Volonteri +8
Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predic…
Tracking on-the-fly massive black hole binary evolution and coalescence in galaxy simulations: RAMCOAL
Kunyang Li, Marta Volonteri, Yohan Dubois +2
The detection of gravitational waves (GWs) from massive black hole binary (MBHB) coalescence motivates the development of a sub-grid model. We present RAMCOAL, integrated into the…
Exploring Active Galactic Nuclei and Little Red Dots with the Obelisk simulation
M. Volonteri, M. Trebitsch, J. E. Greene +8
The James Webb Space telescope has discovered an abundant population of broad line emitters, typical signposts for Active Galactic Nuclei (AGN). Many of these sources have red colo…
Galaxies with grains: unraveling dust evolution and extinction curves with hydrodynamical simulations
Yohan Dubois, Francisco Rodríguez Montero, Corentin Guerra +6
We introduce a model for dust evolution in the RAMSES code for simulations of galaxies with a resolved multiphase interstellar medium. Dust is modelled as a fluid transported with…
Cosmic evolution of black hole-spin and galaxy orientations: clues from the NewHorizon and Galactica simulations
Sebastien Peirani, Yasushi Suto, Ricarda S. Beckmann +10
(Reduced) Using the recent cosmological high-resolution zoom-in simulations, NewHorizon and Galactica, in which the evolution of black hole spin is followed on the fly, we have tra…
