Marginally Stable Circular Orbits in Schwarzschild Black Hole Surrounded by Quintessence Matter
Ibrar Hussain, Sajid Ali
Marginally stable circular orbits (MSCOs) of a massive test particle are investigated in the spacetime geometry of Schwarzschild black hole surrounded by quintessence. For that mat…
A study of positive energy condition in Bianchi V spacetimes via Noether symmetries
Sajid Ali, Ibrar Hussain
In this paper we use Noether symmetries of the geodesic Lagrangian in Bianchi V spacetimes to study various cosmological solutions of Einstein's field equations. Our first result i…
Revisiting Noether gauge symmetry approach in quintom cosmology
Sajid Ali
The Noether gauge symmetry approach is revisited to study various quintom scenarios (those that arise by the presence of two dynamical scalar fields) to comprehend the role of dark…
Effect of quintessence on the energy of the Reissner-Nordstrom black hole
Ibrar Hussain, Sajid Ali
The energy content of the Reissner-Nordstrom black hole surrounded by quintessence is investigated using approximate Lie symmetry methods. It is mainly done by assuming mass and ch…
