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.
