Supermassive black hole at the center of the Milky Way Sagittarius A* was found to have formed around nine billion years ago by a major merger of galaxies. Research suggests that Sgr A* was formed as a result of this collision that occurred in the past. This finding provides important clues about the formation of the giant black hole at the center of our Milky Way.

The survey was conducted by the Event Horizon Telescope (EHT) and began imaging the black hole at the center of the M87 galaxy in 2017. EHT in 2022 Sgr A* in the center of the Milky WayHe collected this data by observing. The data obtained showed that Sgr A* is rotating at high speed and is not aligned with the plane of the Milky Way. Computer simulations support that these rotational features may have originated as a result of a past merger of galaxies.

The oblique rotation of Sgr A shapes our galactic past

Researchers suggest that this merger may have occurred with an ancient satellite galaxy called Gaia-Enceladus. This, Sgr A*’This reveals that the rotation angle of the galaxy is 145-180 degrees, and this feature provides important information about the dynamical history of our galaxy.

Supermassive black holes Understanding how it forms and grows will help us unravel the building blocks of the universe. However, direct observation of such mergers remains beyond the reach of existing gravitational wave detectors. In the future, space-based projects such as LISA could detect gravitational waves at this low frequency, providing more information about the composition of supermassive black holes.
