New Discoveries On Supermassive Black Holes Can Change The Existing Theories

Every single galaxy has one big black hole in its center. Milky Way, for example, has the Sagittarius A black hole which is 4 million times larger than our Sun. Scientists believed that the size of the black holes from the center of every galaxy is directly dependent on the galaxy’s size, how much it eats up, and how much light it spits out. However, new discoveries on supermassive black holes found something more interesting about them.

Two teams studied supermassive black holes in two different ways

The scientists decided to split up into two teams, each team having its own mission. The teams analyzed the data about more than 1,000 galaxies and their black holes, data which was collected by the Chandra Telescope.

The first team decided to study the supermassive black holes growth rates and compared them with those of the galaxies hosts.

The second team studied the connection between the X-Ray and radio emissions of supermassive black holes and their mass.

Guang Yang, the leader of the first team, and his colleagues observed that in bigger galaxies, the black holes are growing much faster than previous theories stated.

Mar Mezuca, the leader of the second team, and her colleagues discovered that the black holes in bright galaxies at the center of galaxies clusters are the biggest and their mass is 10 times larger than previous theories and studies revealed.

What did this study reveal, precisely?

Mezuca, Yang, and their science teams showed that the theories regarding massive black holes should be revised since they are no longer applicable to the reality regarding the mass of the black holes.

More precisely, the new study showed that the relationships between supermassive black holes and their galaxies that host them are much more complex than what the astronomers have theorized in the past decades.
