Probing black holes in a dark matter spike of M87 using quasinormal modes
European Physical Journal C: Particles and FieldsDark matter density can be significantly enhanced by the supermassive black hole at the galactic center, leading to a structure called dark matter spike. Dark matter spike may change the spacetime properties of black holes that constitute deviations from

Dynamics around supermassive black holes
, 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.

Using of the Correction Schwarzschild radius Equation and Its Application of the Black Holes
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 This study is a try to compare between the traditional Schwarzschild’s radius and the equation of Schwarzschild’s radius including the photon’s wavelength that is suggested by Kanarev for black holes to correct the error in the calculation of ...

Time delay of light in the gravitational lensing of supermassive black holes in dark matter halos
European Physical Journal C: Particles and FieldsThe dark matter halo has non-negligible effects on the gravitational lensing of supermassive black hole in the galaxy center. Our work presents a study on the time-delay of light in gravitational lensing of black holes enclosed by dark matter halos.
