Joint Formation of Supermassive Black Holes and Galaxies [PDF]

open access: yesarXiv, 2003
The tight correlation between black hole mass and velocity dispersion of galactic bulges is strong evidence that the formation of galaxies and supermassive black holes are closely linked. I review the modeling of the joint formation of galaxies and their central supermassive black holes in the context of the hierarchical structure formation paradigm.

Evolution of black hole shadow in the presence of ultralight bosons

open access: yesPhysics Letters B, 2020
Kerr black holes coupled to quantized bosonic fields display a special version of the Hawking effect, governed by the superradiance condition. This leads to rapid growth of boson cloud through spontaneous creation, leading to slowing down of the black ...

Weak and strong deflection gravitational lensing by a renormalization group improved Schwarzschild black hole

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Weak and strong deflection gravitational lensing by a renormalization group improved Schwarzschild black hole is investigated and its observables are found. By taking the supermassive black holes Sgr A* and M87* respectively in the Galactic Center and at

Charged and magnetized particle motion around a static black hole in the Starobinsky–Bel–Robinson gravity

open access: yesEuropean Physical Journal C: Particles and Fields
In this work we focus on the effects of Starobinsky–Bel–Robinson (SBR) gravity parameter and external magnetic field on the motion of charged test particles and magnetic dipoles moving around a black hole in the selected gravity theory.
