The first supermassive black holes [PDF]
Astronomy & Geophysics, 2017 We briefly review the historical development of the ideas regarding the first supermassive black hole seeds, the physics of their formation and radiative feedback, recent theoretical and observational progress, and our outlook for the future.

Growth of Supermassive Black Holes, Galaxy Mergers and Supermassive Binary Black Holes [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe study of galaxy mergers and supermassive binary black holes (SMBBHs) is central to our understanding of the galaxy and black hole assembly and (co-)evolution at the epoch of structure formation and throughout cosmic history. Galaxy mergers are the sites of major accretion episodes, they power quasars, grow supermassive black holes (SMBHs ...

Supermassive Black Holes [PDF]
Journal of High Energy Physics, Gravitation and Cosmology, 2019 In the following black hole model, electrons and positrons form a neutral gas which is confined by gravitation. The smaller masses are supported against gravity by electron degeneracy pressure. Larger masses are supported by ideal gas and radiation pressure. In each case, the gas is a polytrope which satisfies the Lane-Emden equation.

Key Science Goals for the Next-Generation Event Horizon Telescope
Galaxies, 2023 The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way.

A FUNDAMENTAL EQUATION FOR SUPERMASSIVE BLACK HOLES [PDF]
International Journal of Modern Physics D, 2011 We developed a theoretical model that is able to give a common origin to the correlations between the mass M• of supermassive black holes and the mass, velocity dispersion, kinetic energy and momentum parameter of the corresponding host galaxies. Our model is essentially based on the transformation of the angular momentum of the interstellar material,

European Physical Journal C: Particles and Fields, 2023 Supermassive black holes from the center of galaxy may be immersed in a dark matter halo. This dark matter halo may form a “cusp” structure around the black hole and disappear at a certain distance from the black hole.

High-energy signatures of binary systems of supermassive black holes [PDF]
, 2016 Context. Binary systems of supermassive black holes are expected to be strong sources of long gravitational waves prior to merging. These systems are good candidates to be observed with forthcoming space-borne detectors.

The cosmogony of supermassive black holes [PDF]
Monthly Notices of the Royal Astronomical Society, 2011 We report calculations of the evolution, under Reynolds viscosity, of the massive gaseous accretion discs thought to form in the centres of galaxies as a result of major galactic mergers at early epochs. Starting with the formation of such a disc and the postulated existence of a low-mass 'seed' black hole, we focus on the mass accretion rate, , and ...

Gravitational lensing by a quantum deformed Schwarzschild black hole
European Physical Journal C: Particles and Fields, 2021 We investigate the weak and strong deflection gravitational lensing by a quantum deformed Schwarzschild black hole and find their observables. These lensing observables are evaluated and the detectability of the quantum deformation is assessed, after ...
