Observational aspects of a class of Dark matter spacetimes
Ashok B. Joshi, Divya Tahelyani, Dipanjan Dey +1
Various astrophysical and cosmological observations today serve as an indirect evidence of the existence of dark matter in the universe. In the present work, we propose a class of…
Relativistic orbits of S2 star in the presence of scalar field
Parth Bambhaniya, Ashok B. Joshi, Dipanjan Dey +4
The general theory of relativity predicts the relativistic effect in the orbital motions of S-stars which are orbiting around our Milky-way galactic center. The post-Newtonian or h…
Light trajectory and shadow shape in the rotating naked singularity
Vishva Patel, Divya Tahelyani, Ashok B. Joshi +2
In this paper, we investigate the light trajectories and shadow properties in the rotating version of null naked singularity (NNS) spacetime which is derived using the Newman- Jani…
Comparing thin accretion disk properties of naked singularities and black holes
Divya Tahelyani, Ashok B. Joshi, Dipanjan Dey +1
In the present paper, we study the thermal properties of the geometrically thin accretion disks surrounding the null naked singularity (NNS) and the first type of Joshi-Malafarina-…
