Local supermassive black holes, relics of active galactic nuclei and the X-ray background [PDF]
, 2004 We quantify the importance of mass accretion during AGN phases in the growth of supermassive black holes (BH) by comparing the mass function of black holes in the local universe with that expected from AGN relics, which are black holes grown entirely ...

Signatures of primordial black holes as seeds of supermassive black holes [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 It is broadly accepted that Supermassive Black Holes (SMBHs) are located in the centers of most massive galaxies, although there is still no convincing scenario for the origin of their massive seeds. It has been suggested that primordial black holes (PBHs) of masses $\gtrsim 10^{2} M_\odot$ may provide such seeds, which would grow to become SMBHs.

Searching for ultra-light bosons and constraining black hole spin distributions with stellar tidal disruption events [PDF]
Nature Communications, 2022 Stellar tidal disruption events (TDEs) occur when stars pass close enough to supermassive black holes. Here, the authors show that future searches TDEs have potential to uncover the existence of ultralight bosons.

Dynamics around supermassive black holes [PDF]
, 2007 The dynamics of galactic nuclei reflects the presence of supermassive black holes (SBHs) in many ways. Single SBHs act as sinks, destroying a mass in stars equal to their own mass in roughly one relaxation time and forcing nuclei to expand.

Signals of merging supermassive black holes in pulsar timing arrays [PDF]
Physical Review Research, 2023 In this work we evaluate whether the gravitational wave background recently observed by a number of different pulsar timing arrays could be due to merging supermassive black hole binaries. We find that for homogeneously distributed primordial black holes

The ASTRID simulation: the evolution of Supermassive Black Holes [PDF]
, 2021 We present the evolution of black holes (BHs) and their relationship with their host galaxies in Astrid, a large-volume cosmological hydrodynamical simulation with box size 250 $h^{-1} \rm Mpc$ containing $2\times5500^3$ particles evolved to z=3.

Supermassive Black Holes as Possible Sources of Ultrahigh-energy Cosmic Rays [PDF]
Astrophysical Journal, 2020 The production and acceleration mechanisms of ultrahigh-energy cosmic rays (UHECRs) of energy >1020 eV, clearly beyond the GZK cutoff limit, remain unclear, which points to the exotic nature of the phenomena.

Seeding Supermassive Black Holes with Self-interacting Dark Matter: A Unified Scenario with Baryons [PDF]
Astrophysical Journal Letters, 2020 Observations show that supermassive black holes (SMBHs) with a mass of ∼109 M ⊙ exist when the universe is just 6% of its current age. We propose a scenario where a self-interacting dark matter halo experiences gravothermal instability and its central ...
