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…
Dyonic string-like solution in a non-Abelian gauge theory with two potentials
Buddhi Vallabh Tripathi, Hemwati Nandan, K D Purohit
Axially symmetric dyon solutions of a non-Abelian gauge theory model with two potentials are sought. While seeking axially symmetric (flux tube like solutions) for the model, we st…
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…
Neutral Current Elastic Interactions in MiniBooNE
Ranjan Dharmapalan
Neutral Current Elastic (NCE) interactions in MiniBooNE are discussed. In the neutrino mode MiniBooNE reported: the flux averaged NCE differential cross section as a function of fo…
