Exact relativistic Newtonian representation of gravitational static spacetime geometries
Shubhrangshu Ghosh, Tamal Sarkar, Arunava Bhadra
We construct a self-consistent relativistic Newtonian analogue corresponding to gravitational static spherical symmetric spacetime geometries, staring directly from a generalized s…
Effects of dark energy and flat rotation curve on the gravitational time delay of particle with non-zero mass
Tamal Sarkar, Shubhrangshu Ghosh, Arunava Bhadra
The effects of several dark energy models on gravitational time delay of particles with non-zero mass are investigated and analytical expressions for the same are obtained at the f…
Newtonian analogue of static general relativistic spacetimes: An extension to naked singularities
Shubhrangshu Ghosh, Tamal Sarkar, Arunava Bhadra
We formulate a generic Newtonian like analogous potential for static spherically symmetric general relativistic (GR) spacetime, and subsequently derived proper Newtonian like analo…
Newtonian analogue of Schwarzschild de-Sitter spacetime: Influence on the local kinematics in galaxies
Tamal Sarkar, Shubhrangshu Ghosh, Arunava Bhadra
The late time accelerated expansion of the Universe demands that even in local galactic-scales it is desirable to study astrophysical phenomena, particularly relativistic accretion…
