Shadow of Kottler black hole in the presence of plasma for a co-moving observer
Anish Das, Ashis Saha, Sunandan Gangopadhyay
We consider a spherically symmetric black hole metric in (3+1)-dimensions in presence of a positive cosmological constant . We use a general approach as proposed in \cite{1} to…
Study of circular geodesics and shadow of rotating charged black hole surrounded by perfect fluid dark matter immersed in plasma
Anish Das, Ashis Saha, Sunandan Gangopadhyay
In this work, we consider a rotating charged black hole surrounded by perfect fluid dark matter. We consider the system to be immersed in non-magnetised, pressureless plasma. First…
Investigation of circular geodesics in a rotating charged black hole in the presence of perfect fluid dark matter
Anish Das, Ashis Saha, Sunandan Gangopadhyay
In this work we have obtained a charged black hole solution in the presence of perfect fluid dark matter (PFDM) and discuss its energy conditions. The metric corresponding to the r…
Shadow of charged black holes in Gauss-Bonnet gravity
Anish Das, Ashis Saha, Sunandan Gangopadhyay
In this paper, we investigate the effect of higher curvature corrections from Gauss-Bonnet gravity on the shadow of charged black holes in both and Minkowski spacetimes. The…
