We study the perturbation induced by a slowly rotating massive object as it
passes through a Rindler horizon. It is shown that the passage of this object effectively induces a process which can be approximately modeled as Delta function
type tidal distortions hitting the horizon. Further, following the analysis presented
by Amsel, Marolf and Virmani related to the issue of the validity of...

We show that the fine tuning problem of the cosmological constant can be
solved in a conformal model, with explicit conformal symmetry breaking.
We argue that the model has two different terms which essentially
contribute to the cosmological constant. A local conformal transformation leads
to a cancellation of these two terms among one another.
Hence these produce no physical consequence...

A singularity free cosmological model is obtained in a homogeneous and
isotropic background with a specific form of the Hubble parameter in the
presence of an interacting dark energy represented by a time-varying
cosmological constant in general relativity. Different cases so arose have
extensively been studied for different values of curvature parameter. Some
interesting results have...

The singularity free spacetime metric described by Krori-Barua (J. Phys. A, Math. Gen. 8:508, 1975) satisfies all the requirements of a realistic star. Consequently, we explore the possibility of applying the Krori and Barua model to describe ultra-compact objevts like strange stars.

Importance of the late time accelerated expansion of the Universe in the study of astrophysical phenomena in local galactic-scales is highlighted. From the principle of conserved Hamiltonian of the test particle motion a three dimensional Newtonian analogous potential has been obtained in spherical geometry corresponding to Schwarzschild de Sitter space time, that reproduces almost all of the...
