Echoes of a hairy black hole from gravitational decoupling

Yi Yang, Ali Ovgun, Gaetano Lambiase +2

We study axial gravitational perturbations of a hairy black hole constructed within the framework of gravitational decoupling and investigate the geometric origin of echo-like late…

Ringdown of a black hole sourced by a Burkert-density effective anisotropic source

Yi Yang, Gaetano Lambiase, Ali Ovgun +2

We construct a static, spherically symmetric black hole spacetime sourced by an effective anisotropic matter distribution whose energy density follows the cored Burkert profile. Th…

Cohomology and deformations of nonabelian embedding tensors between Lie triple systems

Wen Teng

In this paper, first we introduce the notion of nonabelian embedding tensors between Lie triple systems and show that nonabelian embedding tensors induce naturally 3-Leibniz algebr…

An analysis of the longitudinal structure function at next-to-leading order approximation at small-

G. R. Boroun, Yanbing Cai

The longitudinal structure function is considered at the next-to-leading order approximation using the expansion method, as defined by M.B.Gay Ducati and P.B.Goncalves [Phys.Lett.B…

Probing black holes in a dark matter spike of M87 using quasinormal modes

Dong Liu, Yi Yang, Zheng-Wen Long

Dark 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 chan…
