Black Holes growing faster than expected: astronomers

Astronomers had already discovered that the super-massive black holes which sit in the centers of various galaxies were growing faster. But according to new observations by Swinburne University of Technology, astronomers show that these black holes were grown by much faster than expected.

Prof. Alister Graham of Technology Swinburne Centre for Astrophysics and Supercomputers explained that several galaxies were competing for available gases, for creating new stars or feed central black hole. In the past 10 years, the main theories and models fixed fraction of gas easier to all of this process, the ratio between black hole mass to galaxy mass.

Professor Graham explained that every time a ten times larger stellar mass of the galaxy, it leads to about 100 times the mass of black hole.

Apart from this concept, the researchers also found an existence of opposing behaviors that attended the bulges of clusters of stars that are found in the centers of galaxies and disk galaxies such as Milky Way.

Smaller galaxies meant that a larger fraction of stars in the dense and compact clusters. In lower mass galaxies, the star clusters in the millions of stars, dominate these black holes. Initially, the cluster should have a constant 0.2% of the large number of galaxies.
