It is known that the main consumers of interstellar gas are stars and black holes. Thanks to numerous mathematical models and complex theoretical calculations for the last decade has been able to determine how much gas in galaxies are absorbed by black holes, and which by stars. However, if you believe the work published by Australian scientists in Astrophysical Journal, existing calculations are subject to adjustment. Researchers write that stellar observations clusters using the Hubble telescope, as well as the European Southern Observatory (ESO) in South America and the Keck Observatory in Hawaii (W. M. Keck Observatory) provided unique information on the development and interaction of black holes and galaxies. “Black holes grow much faster than we thought, ”says Professor Alister Graham (Alister Graham), known to us for the opening of the rectangular galaxies. – Now we know that every tenfold increase stellar mass is accompanied by a hundredfold increase in black mass holes. “Black holes grow ten times faster than stars (illustration by Gabriel Perez Diaz).

An interesting conclusion was made by scientists regarding small galaxies, in particular spiral ones, like our Milky Way, putting under doubt the old attitude that the star cluster is always accounts for 0.2% of the mass of the galaxy. “The smaller the galaxy, the larger we observe stars in star clusters, says the doctor Nicholas Scott of the University of Technology Swinburne. – In the center of small galaxies is pretty tight millions of stars are located, significantly predominant over black holes. “Curiously, scientists predict the existence of black holes in every galaxy, thus explaining the elusive paradox (rare) black holes of medium weight.
