Strong lensing and Observables around 5D Myers-Perry black hole spacetime
Ravi Shankar Kuniyal, Hemwati Nandan, Uma Papnoi +2
We study the motion of massless test particles in a five dimensional (5D) Myers-Perry black hole spacetime with two spin parameters. The behaviour of the effective potential in vie…
Null Geodesics and Red-Blue Shifts of Photons Emitted from Geodesic Particles Around a Non-Commutative Black Hole Spacetime
Ravi Shankar Kuniyal, Rashmi Uniyal, Anindya Biswas +2
We investigate the geodesic motion of massless test particles in the background of a noncommutative geometry inspired Schwarzschild black hole. The behaviour of effective potential…
Null Geodesics and Observables around Kerr-Sen Black Hole
Rashmi Uniyal, Hemwati Nandan K. D. Purohit
We investigate the geodesic motion in the background of Kerr-Sen Black Hole arising in the heterotic string theory. The nature of effective potential is discussed in radial as well…
Null Geodesics in a Magnetically Charged Stringy Black Hole Spacetime
Ravi Shankar Kuniyal, Rashmi Uniyal, Hemwati Nandan +1
We study the geodesic motion of massless test particles in the background of a magnetic charged black hole spacetime in four dimensions in dilaton-Maxwell gravity. The behaviour of…
Geodesic motion in R- charged black hole space-times
Rashmi Uniyal, Anindya Biswas, Hemwati Nandan +1
We study the geodesic motion of massive and massless test particles in the background of a particular class of multiple charge black holes in gauged supergravity theories in D = 4.…
Gravitating Dyons in Vaidya Geometry
Buddhi Vallabh Tripathi, Hemwati Nandan, Heinz Dehnen +1
Gravitating monopoles and dyons in Einstein-Yang-Mills (EYM) or Einstein-Yang-Mills-Higgs (EYMH) systems have been extensively studied for various curved spacetimes, including thos…
Geodesic Motion in a Charged 2D Stringy Blackhole Spacetime
Rashmi Uniyal, Hemwati Nandan, K. D. Purohit
We study the timelike geodesics and geodesic deviation for a two-dimensional stringy blackhole spacetime in Schwarzschild gauge. We have analyzed the properties of effective potent…
Geodesic Motion in Schwarzschild Spacetime Surrounded by Quintessence
Rashmi Uniyal, N. Chandrachani Devi, Hemwati Nandan +1
We study the time-like geodesic congruences, in the space-time geometry of a Schwarzschild black hole surrounded by quintessence. The nature of effective potential along with the s…
