GRMHD accretion beyond the black hole paradigm: Light from within the shadow
Saurabh, Maciek Wielgus, Parth Bambhaniya +3
We present the first three-dimensional general relativistic magnetohydrodynamic simulation of sustained accretion onto a horizonless singularity in which matter reaches the central…
Quasinormal Modes and Stability Analysis of the JMN-1 Naked Singularity
Akshat Pathrikar, Parth Bambhaniya, Pankaj S. Joshi +1
In this paper, we perform a comprehensive analysis of the quasinormal modes in an external geometry of the Joshi-Malafarina-Narayan (JMN-1) naked singularity by investigating its r…
Retrograde Precession of Relativistic Orbits and the Quest for Charged Black Holes
Parth Bambhaniya, Meet J. Vyas, Pankaj S. Joshi +1
The S-stars around the center of the milky way galaxy provide us with detailed information about the nature of the supermassive compact object Sagittarius A* (Sgr A*). In this work…
Magnetic Penrose Process and Kerr Black Hole Mimickers
Divyesh P. Viththani, Tapobroto Bhanja, Vishva Patel +1
The present study investigates the negative energy orbits and energy extraction efficiency using the magnetic Penrose process in various regular black hole geometries surrounded by…
Relativistic time delay analysis of pulsar signals near ultra-compact objects
Viraj Kalsariya, Parth Bambhaniya, Pankaj S. Joshi
The upcoming discoveries of pulsars orbiting the center of the Milky Way will present unparalleled opportunities to examine the causal structure of the spacetime geometry of Sagitt…
