Shattering and growth of cold clouds in galaxy clusters: the role of radiative cooling, magnetic fields and thermal conduction
Fred Jennings, Ricarda Beckmann, Debora Sijacki +1
In galaxy clusters, the hot intracluster medium (ICM) can develop a striking multi-phase structure around the brightest cluster galaxy. Much work has been done on understanding the…
Population statistics of intermediate mass black holes in dwarf galaxies using the NewHorizon simulation
R. S. Beckmann, Y. Dubois, M. Volonteri +6
While it is well established that supermassive black holes (SMBHs) co-evolve with their host galaxy, it is currently less clear how lower mass black holes, so-called intermediate m…
Evidence for non-merger co-evolution of galaxies and their supermassive black holes
R. J. Smethurst, R. S. Beckmann, B. D. Simmons +7
Recent observational and theoretical studies have suggested that supermassive black holes (SMBHs) grow mostly through non-merger (`secular') processes. Since galaxy mergers lead to…
Supermassive black holes in merger-free galaxies have higher spins which are preferentially aligned with their host galaxy
R. S. Beckmann, R. J. Smethurst, B. D. Simmons +7
Here we use the Horizon-AGN simulation to test whether the spins of SMBHs in merger-free galaxies are higher. We select samples using an observationally motivated bulge-to-total ma…
Dynamical friction of a massive black hole in a turbulent gaseous medium
Sandrine Lescaudron, Yohan Dubois, Ricarda S. Beckmann +1
The orbital decay of massive black holes in galaxies in the aftermath of mergers is at the heart of whether massive black holes successfully pair and merge, leading to emission of…
How the super-Eddington regime affects black hole spin evolution in high-redshift galaxies
Warren Massonneau, Yohan Dubois, Marta Volonteri +1
By performing three-dimensional hydrodynamical simulations of a galaxy in an isolated dark matter halo, we follow the evolution of the spin parameter of a black hole (BH) under…
AGN jets do not prevent the suppression of conduction by the heat buoyancy instability in simulated galaxy clusters
Ricarda S. Beckmann, Yohan Dubois, Alisson Pellissier +2
Centres of galaxy clusters must be efficiently reheated to avoid a cooling catastrophe. One potential reheating mechanism is anisotropic thermal conduction, which could transport t…
Cosmic rays and thermal instability in self-regulating cooling flows of massive galaxy clusters
Ricarda S. Beckmann, Yohan Dubois, Alisson Pellissier +5
One of the key physical processes that helps prevent strong cooling flows in galaxy clusters is the continued energy input from the central active galactic nucleus (AGN) of the clu…
Gas condensation in Brightest Group Galaxies unveiled with MUSE
V. Olivares, P. Salome, S. L. Hamer +18
The origin of the cold gas in central galaxies in groups is still a matter of debate. We present Multi-Unit Spectroscopic Explorer (MUSE) observations of 18 optically selected loca…
How the super-Eddington regime regulates black hole growth in high-redshift galaxies
Warren Massonneau, Marta Volonteri, Yohan Dubois +1
Super-Eddington accretion is one scenario that may explain the rapid assembly of supermassive black holes (BHs) within the first billion year of the Univer…
