Shadow of the rotating black hole with quintessential energy in the presence of the plasma
Ahmadjon Abdujabbarov, Bobir Toshmatov, Zdeněk Stuchlík +1
We study the shadow of the rotating black hole with quintessential energy i) in vacuum and ii) in the presence of plasma with radial power-law density. For vacuum case the quintess…
Rotating black hole solutions with quintessential energy
Bobir Toshmatov, Zdeněk Stuchlík, Bobomurat Ahmedov
Quintessential dark energy with density and pressure is governed by an equation of state of the form with the quintessential parameter . We der…
Quasinormal modes of test fields around regular black holes
Bobir Toshmatov, Ahmadjon Abdujabbarov, Zdeněk Stuchlík +1
We study scalar, electromagnetic and gravitational test fields in the Hayward, Bardeen and Ayón-Beato-García regular black hole spacetimes and demonstrate that the test fields are…
