The impact of superradiance on the spin evolution of variably accreting massive black holes
Adithya Nandakumar, Ricarda S. Beckmann, Vid Irsic
This paper explores how time-varying increases in mass accretion onto rapidly spinning black holes influence their long-term spin evolution when affected by superradiance - a proce…
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…
The High Energy X-ray Probe (HEX-P): Constraining Supermassive Black Hole Growth with Population Spin Measurements
J. M. Piotrowska, J. A. García, D. J. Walton +24
Constraining the primary growth channel of supermassive black holes (SMBH) remains one the most actively debated questions in the context of cosmological structure formation. Owing…
Multimessenger study of merging massive black holes in the OBELISK simulation: gravitational waves, electromagnetic counterparts, and their link to galaxy and black hole populations
C. A. Dong-Páez, M. Volonteri, R. S. Beckmann +5
Massive black-hole (BH) mergers are predicted to be powerful sources of low-frequency gravitational waves (GWs). Coupling the detection of GWs with an electromagnetic (EM) detectio…
Bondi or not Bondi: the impact of resolution on accretion and drag force modelling for Supermassive Black Holes
Ricarda Sylvia Beckmann, Julien Devriendt, Adrianne Slyz
Whilst in galaxy-size simulations, supermassive black holes (SMBH) are entirely handled by sub-grid algorithms, computational power now allows the accretion radius of such objects…
