Probing the Shadow Image of the Sagittarius A* with Event Horizon Telescope

Understand

Recent observations of the Milky-way galactic center at various frequencies suggest a supermassive compact object.

• Generally, that supermassive compact object is assumed to be a `Black Hole', having more than four million solar masses.
• In this work, we study the observational appearance at $230$ GHz and probe the nature of Sagittarius-A* (Sgr A*) as the naked singularity.
• Here, we consider the first type of Joshi-Malafarina-Narayan (JMN-1) and Janis-Newman-Winicour (JNW) naked singularity spacetimes which are anisotropic fluid solutions of the Einstein field equations.
