Universalization as a physical guiding principle

Naresh Dadhich

In this essay, I wish to share a novel perspective based on the principle of universalization in arriving at the relativistic and quantum world from the classical world. I also del…

The critical role of shear in gravitational collapse

Pankaj S. Joshi, Rituparno Goswami, Naresh Dadhich

We investigate here how the shearing effects present within a collapsing matter cloud influence the outcome of gravitational collapse in terms of formation of either a black hole o…

Embedding Diagrams for the Reissner-Nordström spacetime

Aseem Paranjape, Naresh Dadhich

We consider embedding diagrams for the Reissner-Nordström spacetime. We embed the and planes into 3-Minkowski/Euclidean space and discuss the relation between the d…

The role of the equation of state and the space-time dimension in spherical collapse

Naresh Dadhich, S. G. Ghosh, D. W. Deshkar

We study the spherically symmetric collapse of a fluid with non-vanishing radial pressure in higher dimensional space-time. We obtain the general exact solution in the closed form…

Action based approach to the dynamics of extended bodies in General Relativity

Jeeva Anandan, Naresh Dadhich, Parampreet Singh

We present, for the first time, an action principle that gives the equations of motion of an extended body possessing multipole moments in an external gravitational field, in the w…

Scalar and Spinor Perturbation to the Kerr-NUT Spacetime

Banibrata Mukhopadhyay, Naresh Dadhich

We study the scalar and spinor perturbation, namely the Klein-Gordan and Dirac equations, in the Kerr-NUT space-time. The metric is invariant under the duality transformation invol…
