[HTML][HTML] Shadow and quasinormal modes of the Kerr–Newman–Kiselev–Letelier black hole

F Atamurotov, I Hussain, G Mustafa, K Jusufi - The European Physical …, 2022 - Springer
We investigate the null geodesics and the shadow cast by the Kerr–Newman–Kiselev–
Letelier (KNKL) black hole for the equation of state parameter\(\omega _q=-2/3\) and for …

Investigating effects of dark matter on photon orbits and black hole shadows

A Anjum, M Afrin, SG Ghosh - Physics of the Dark Universe, 2023 - Elsevier
We consider Kerr black holes (BHs) surrounded by perfect dark fluid matter (PFDM), with an
additional parameter (k) because of PFDM, apart from mass (M) and rotation parameter (a) …

Quasinormal modes and thermodynamic properties of GUP-corrected Schwarzschild black hole surrounded by quintessence

R Karmakar, DJ Gogoi, UD Goswami - International Journal of …, 2022 - World Scientific
We study the Quasinormal Modes (QNMs) of the Schwarzschild black hole surrounded by a
quintessence field after implementing the quantum corrections to its solution as required by …

Quasinormal modes, shadow, and greybody factors of 5D electrically charged Bardeen black holes

K Jusufi, M Amir, MS Ali, SD Maharaj - Physical Review D, 2020 - APS
We study quasinormal modes (QNMs) in a five-dimensional electrically charged Bardeen
black hole spacetime by considering the scalar and electromagnetic field perturbations. The …

Testing the weak cosmic censorship conjecture for a Reissner–Nordström–de Sitter black hole surrounded by perfect fluid dark matter

S Shaymatov, B Ahmedov, M Jamil - The European Physical Journal C, 2021 - Springer
In this paper, we test the weak cosmic censorship conjecture (WCCC) for the Reissner–
Nordström–de Sitter (RN-dS) black hole surrounded by perfect fluid dark matter. We …

Does the shape of the shadow of a black hole depend on motional status of an observer?

Z Chang, QH Zhu - Physical Review D, 2020 - APS
