Causal Structure of Spacetime Singularities and Their Observable Signatures
Bina Patel, Jahnvi Mistry, Ayush Bidlan +1
We analyze the causal structure of horizonless compact objects via the light-cone geometry and conformal compactification of the Joshi-Malafarina-Narayan (JMN-1) and Janis-Newman-W…
Testing the Spacetime Geometry of Sgr A* with the Relativistic Orbit of S2 star
Parth Bambhaniya, Preet Dalal, Giovani H. Vicentin +3
In this work, we perform a relativistic test of the spacetime geometry of Sagittarius A* (Sgr A*) using the orbit of the S2 star. We consider a broad class of compact object models…
Gravitational Collapse and Singularity Formation in Brans-Dicke Gravity
Ayush Bidlan, Dipanjan Dey, Parth Bambhaniya
We investigate gravitational collapse driven solely by a self-interacting Brans--Dicke (BD) scalar field in the absence of ordinary matter. In this framework, the spacetime dynamic…
