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 region collapses into a seed black hole. The presence of baryons in protogalaxies could significantly accelerate the gravothermal evolution of the halo and shorten collapse timescales. The central halo could dissipate its angular momentum remnant… 
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
Snowmass2021 Cosmic Frontier White Paper:Primordial Black Hole Dark Matter
Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the dark matter and provide a unique window into the high-energy physics of the early universe. This white paper
Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, and spins of these
Supermassive Black Holes, Ultralight Dark Matter, and Gravitational Waves from a First Order Phase Transition.
The formation of ultrarare supermassive black holes (SMBHs), with masses of O(10^{9}  M_{⊙}), in the first billion years of the Universe remains an open question in astrophysics. At the same time,
Fourth Generation fermions providing new candidates for Dark Matter and Dark Energy
Clifford Unification describes all known elementary fermions and their interactions, providing a useful tool in the analysis of experimental data. It also predicts the existence of a stable fourth
Constraining self-interacting dark matter with dwarf spheroidal galaxies and high-resolution cosmological N -body simulations
We study the density structures of dark matter subhalos for both cold dark matter and selfinteracting dark matter models using high-resolution cosmological N -body simulations. We quantify subhalo’s
Self-Interacting Dark Scalar Spikes around Black Holes via Relativistic Bondi Accretion
We consider the spike mass density profile in a dark halo by self-consinstently solving the relativisitic Bondi accretion of dark matter onto a non-spining black hole of mass M . We assume that the
On the Dynamical Instability of Monatomic Fluid Spheres in (N+1)-dimensional Spacetime
Wei-Xiang Feng1, ∗ 1Department of Physics and Astronomy, University of California, Riverside, CA 92521 Abstract In this note, I derive the Chandrasekhar instability of a fluid sphere in
Galaxy Formation and Rotation as a 4D Relativistic Cloud-World Embedded in a 4D Conformal Background: A Cloud Theory
The recent observation of the G2 gas cloud orbit around the galactic centre has challenged the model of a mere supermassive black hole at the centre of our galaxy which should have destroyed it. In
Is the gravity–matter system time-reversible?
Presented are logical arguments for Dark Matter. You are free not to get enlightened about that fact. But please pay respect to new dispositions of the Dark Matter and research methods in this note.
