Wandering Supermassive Black Holes in Milky-Way-mass Halos [PDF]
, 2018 We present a self-consistent prediction from a large-scale cosmological simulation for the population of “wandering” supermassive black holes (SMBHs) of mass greater than 106 M ⊙ on long-lived, kpc-scale orbits within Milky Way (MW)-mass galaxies.

Ram-pressure feeding of supermassive black holes [PDF]
Nature, 2017 When a supermassive black hole at the centre of a galaxy accretes matter, it gives rise to a highly energetic phenomenon: an active galactic nucleus. Numerous physical processes have been proposed to account for the funnelling of gas towards the galactic

The Astrophysical Journal, 2023 The early evolution of the quasar luminosity function (QLF) and black hole mass function (BHMF) encodes key information on the physics determining the radiative and accretion processes of supermassive black holes (BHs) in high- z quasars.

Hierarchical build-up of galactic bulges and the merging rate of supermassive binary black holes
, 2003 The hierarchical build-up of galactic bulges should lead to the build-up of present-day supermassive black holes by a mixture of gas accretion and merging of supermassive black holes.

Detection of Coronal Magnetic Activity in nearby Active Supermassive Black Holes [PDF]
Astrophysical Journal, 2018 Central supermassive black holes of active galactic nuclei host hot plasma with a temperature of 109 K, namely coronae. Like the Sun, black hole coronae are theoretically believed to be heated by their magnetic activity, which have not been observed yet.

Supermassive Black Hole Feedback
, 2019 Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern astrophysics. We now know that the evolution of galaxies is critically shaped by the energy injection from accreting supermassive black holes (SMBHs). However, it is unclear how

Primordial black holes as dark matter candidates
SciPost Physics Lecture Notes, 2022 We review the formation and evaporation of primordial black holes (PBHs) and their possible contribution to dark matter. Various constraints suggest they could only provide most of it in the mass windows $10^{17}$ - $10^{23}\,$g or $10$ - $10^{2}\,M_ ...

Orbital Migration of Interacting Stellar Mass Black Holes in Disks around Supermassive Black Holes
, 2019 The merger rate of stellar-mass black hole binaries (sBHBs) inferred by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) suggests the need for an efficient source of sBHB formation.
