Black hole formation is an inevitable consequence of relativistic core collapse following the gravothermal catastrophe in self-interacting dark matter (SIDM) halos. Very massive SIDM halos form supermassive black holes (SMBHs) > or about 10(6)M(middle dot in circle) directly. Smaller halos believed to form by redshift z = 5 produce seed black holes of (10(2)-10(3))M(middle dot in circle) which can merge and/or accrete to reach the observational SMBH range. This scenario for SMBH formation…

Seeding Supermassive Black Holes with Self-interacting Dark Matter: A Unified Scenario with Baryons
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
Dynamical instability of collapsed dark matter halos
A self-interacting dark matter halo can experience gravothermal collapse, resulting in a central core with an ultrahigh density. It can further contract and collapse into a black hole, a mechanism
Collapse of a Rotating Supermassive Star to a Supermassive Black Hole: Fully Relativistic Simulations
We follow the collapse in axisymmetry of a uniformly rotating, supermassive star (SMS) to a supermassive black hole in full general relativity. The initial SMS of arbitrary mass M is marginally
Dark halo microphysics and massive black hole scaling relations in galaxies
We investigate the black hole (BH) scaling relation in galaxies using a model in which the galaxy halo and central BH are a self-gravitating sphere of dark matter (DM) with an isotropic, adiabatic
The onset of gravothermal core collapse in velocity-dependent self-interacting dark matter subhaloes
It has been proposed that gravothermal collapse due to dark matter self-interactions (i.e. self-interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (MW) satellites'
Star clusters, self-interacting dark matter halos, and black hole cusps: The fluid conduction model and its extension to general relativity.
This approximation reproduces the familiar Bahcall-Wolf quasistatic density cusp for the stars bound to the black hole and shows how the cusp halts the "gravothermal catastrophe" and causes the cluster to re-expand.
Horizon growth of supermassive black hole seeds fed with collisional dark matter
We present the accretion of collisional dark matter on a supermassive black hole seed. The analysis is based on the numerical solution of the fully coupled system of Einstein-Euler equations for
Formation and Evolution of the Self-Interacting Dark Matter Halos
We have derived the first, fully-cosmological, similarity solutions for CDM halo formation in the presence of nongravitational collisionality, which provides an analytical theory of the effect of the
Accelerated core collapse in tidally stripped self-interacting dark matter halos
Author(s): Nishikawa, Hiroya; Boddy, Kimberly K; Kaplinghat, Manoj | Abstract: We use a semianalytic approach that is calibrated to N-body simulations to study the evolution of self-interacting dark
Spin, accretion, and the cosmological growth of supermassive black holes
If supermassive black holes (SMBHs) are the energy sources that power quasars and active galactic nuclei (AGNs), then QSO SDSS 1148+5251, the quasar with the highest redshift (zQSO = 6.43), hosts an


Dynamical evolution of globular clusters
One of the world's most distinguished astrophysicists presents a comprehensive theoretical treatment of the dynamical evolution of globular clusters. Lyman Spitzer's research in this field
