Imaging ultra-compact objects with radiatively inefficient accretion flows
Saurabh, Parth Bambhaniya, Pankaj S. Joshi
Recent Event Horizon Telescope observations of M87* and Sgr A* strongly suggests the presence of supermassive black hole at their respective cores. In this work, we use the semi-an…
Tidal forces in the Simpson-Visser black-bounce and wormhole spacetimes
Dhruv Arora, Parth Bambhaniya, Dipanjan Dey +1
The concept of regular black holes has gained attention in recent years, especially in the context of quantum gravity theories. In these theories, the existence of singularities is…
High Energy Particle Collisions in the vicinity of Naked Singularity
Kauntey Acharya, Parth Bambhaniya, Pankaj S. Joshi +2
In this paper, we investigate particle acceleration and high-energy collisions in the Joshi-Malafarina-Narayan (JMN-1) naked singularity, which, in the absence of an event horizon,…
Energy extraction from Janis-Newman-Winicour naked singularity
Vishva Patel, Kauntey Acharya, Parth Bambhaniya +1
In general, energy extraction methods such as the Penrose process and the magnetic Penrose process are thought to be reliant on the existence of an ergoregion. Inside an ergoregion…
