Investigating the Characteristics of Black Holes: Sagittarius A* at the Heart of the Milky Way

The notion of black holes has changed mightily over the past couple of centuries, especially in conjunction with Einstein's theory of general relativity, offering a scaffold for understanding its extreme gravitational properties. This paper will provide an overview of the theoretical principles underlying black holes, with particular emphasis on two important answers to Einsteins field equations: the Schwarzschild solution, which outlines uncharged and non-rotating black holes, and the Kerr solution, which characterizes rotating black holes. We are focusing our conversation on Sagittarius A* (Sgr A*), the enormous black hole situated at the heart of the Milky Way galaxy. This work will demonstrate that, based on observational dataespecially gravitational waves and dual collimated outflowsthere is substantial justification for considering Sgr A* modelled as a Kerr black hole, which indicates significant angular momentum. This carries more general implications for understanding black hole dynamics and what they mean for galaxy formation. More detailed measurements, such as those taken via radio velocity observations and future gravitational wave detectors.
