Effective potential and geodesic motion in Kerr-de Sitter space-time
P. C. Poudel, U. Khanal
In the present work, geodesic trajectories in Kerr-de Sitter geometry is analyzed. From the mathematical solution of Lagrangian formalism appropriate to motions in the equatorial p…

Electric and Magnetic fields due to Dirac particles in FRW spacetime
S. K. Sharma, P. R. Dhungel, U. Khanal
Some solutions of the Maxwell equations with Dirac particles for the source in FRW spacetime are discussed. The Green's function of the equation for the radial component of the Max…

Estimation of mass and cosmological constant of nearby spiral galaxies using galaxy rotation curve
B. Aryal, R. Pandey, N. Baral +2
An expression for rotational velocity of a test particle around the central mass in the invariant plane is derived. For this, a line element of Schwarzschild de-Sitter space-time i…
