Testing gravity at the Second post-Newtonian level through gravitational deflection of massive particles
A. Bhadra, K. Sarkar, K. K. Nandi
Expression for second post-Newtonian level gravitational deflection angle of massive particles is obtained in a model independent framework. Several of its important implications i…
Emergent Universe with Exotic Matter
S. Mukherjee, B. C. Paul, N. K. Dadhich +2
A general framework for an emergent universe scenario has been given which makes use of an equation of state. The general features of the model have also been studied and possible…
Brans-Dicke theory: Jordan vs Einstein Frame
A. Bhadra, K. Sarkar, D. P. Datta +1
It is well known that, in contrast to general relativity, there are two conformally related frames, the Jordan frame and the Einstein frame, in which the Brans-Dicke theory, a prot…
Contribution of a nearby Pulsar to Cosmic Rays observed at Earth
A. Bhadra
Contribution of nearby pulsars to the cosmic rays observed at Earth has been studied. It is found that the experimental bound on amplitude of cosmic ray anisotropy may produce sign…
Gravitational Lensing by Wormholes
Kamal Kanti Nandi, Yuan-Zhong Zhang, Alexander V. Zakharov
Gravitational lensing by traversable Lorentzian wormholes is a ew possibility which is analyzed here in the strong field limit. Wormhole solutions are considered in the Einstein mi…
