Black Hole Measured for the first time at the Center of Spiral Galaxy

The precise mass of a black hole at the center of distant spiral galaxy, were measured for the first time by scientists.

Space scientist utilized the Atacama Large Millimeter/submillimeter Array (ALMA) to measure the mass of the gigantic black hole in the middle of NGC 1097, a banded spiral galaxy situated roughly 45 million light-years away in the course of the constellation Fornax.

The researchers disclosed that this galaxy shelters a black hole 140 million times more colossal as compared to our Sun. In contrast, the black hole found at the center of the Milky Way is lightweight, with a mass of only a few million times that of our Sun.

While NGC 4526 is a lenticular galaxy, NGC 1097 is a barred spiral galaxy. Current observation  outcomes show the association between supermassive black hole mass and the host galaxy properties differs depending on the type of galaxies, which makes it more important to derive accurate supermassive black hole masses in various types of galaxies, noted team leader Kyoko Onishi.

This is the first ever usage of ALMA to make such a dimension for a spiral or barred spiral galaxy, said the co-author, Kartik Sheth.

Since recent theories demonstrate that galaxies and their supermassive black holes develop together, each of them affecting the growth of the other, this new measurement procedure could shed light on the connection between galaxies and their resident supermassive black holes.
