Identify other “foods” of black holes
The formation of quasars, from supermassive black holes, depends more clouds of cosmic gas and solar wind rather than mergers of galaxies. In the center of many galaxies scattered throughout the cosmos, for example, the Milky Way, are colossal black holes, the dimensions become significantly larger than our sun These objects and unleash immeasurable strength does not escape its gravitational pull and light. Because they are not visible due to the absence of light, and just from there comes the name “black hole” – the scientists studied a non-direct, ie, analyzing the dynamics data display while consuming matter.
Interesting study:
Until recently, astronomers believed that quasars with higher light emission is strengthened by impacts between galaxies. However, a team of specialists, where he worked Takamitsu Miyaji, researcher at the Institute of Astronomy of the National Autonomous University of Mexico, has determined that quasars of medium size, which are most numerous in the area, feed more local, such as stellar winds, clouds of cosmic gas and slight disturbances in the galaxies where they are located.
Brightness cosmic:
Quasars, listed as the largest energy sources in the cosmos, are galaxies containing supermassive black holes that suck matter continuously. Within the scope of contemporary astronomy, one of the issues is still pending, is determine where all that stuff is needed to activate the black hole that is located in the nucleus of a galaxy, to the extent become a quasar. The most likely mechanism connected with it is the merger of galaxies.
Study Hard:
The research team of astrophysicists where it participates Takamitsu Miyaji, focused on a section of sky ten times larger than our moon in the constellation Sextans. There are over 600 quasars monitored using mainly the X-ray space telescope called XMM-Newton, the European Space Agency. And so, after five years of analysis, it was discovered that quasars observed were not included in the group of objects radiating cosmos. On the other hand, was identified around the quasars observed large halos of dark matter, which exhibit greater than brightest quasars.
The research results discussed reflect the dynamics of activation black holes within the observed galaxies, quasars generates the same, not so much of galaxy mergers, but rather local changes, concentrations of molecular gas and stellar winds.
