Cosmological dynamics of f(R) models in dynamical system analysis
Parth Shah, Gauranga C. Samanta
In this work we try to understand the late time acceleration of the universe by assuming some modification in the geometry of the space and using dynamical system analysis. This te…
Singularity resolution in gravitational collapse
Karim Mosani, Dipanjan Dey, Kaushik Bhattacharya +1
We investigate the unhindered gravitational collapse of a homogeneous scalar field with nonzero potential, a two-dimensional analog of the Mexican hat-shaped Higgs field potential.…
On the visibility of singularities in general relativity and modified gravity theories
Karim Mosani, Dipanjan Dey, Pankaj S. Joshi +3
We investigate the global causal structure of the end state of a spherically symmetric marginally bound Lemaitre-Tolman-Bondi (LTB) \cite{Lemaitre, Tolman, Bondi} collapsing cloud…
Causal Structure of Singularity in non-spherical Gravitational Collapse
Dipanjan Dey, Pankaj S. Joshi, Karim Mosani +1
We investigate here the final state of gravitational collapse of a non-spherical and non-marginally bound dust cloud as modeled by the Szekeres spacetime. We show that a directiona…
Globally visible singularity in an astrophysical setup
Karim Mosani, Dipanjan Dey, Pankaj S. Joshi
The global visibility of a singularity as an end state of the gravitational collapse of a spherically symmetric pressureless cloud is investigated. We show the existence of a non-z…
Post-Newtonian properties of EMRI with Power Law Potential
Chinmay N. Gandevikar, Divyesh N. Solanki, Dipanjan Dey
There are many astrophysical scenarios where extreme mass ratio inspiral (EMRI) binaries can be surrounded by matter distribution. The distribution of mass can affect the dynamical…
