The holes blacks forge galaxies
Substantial evidence in the last few decades suggests that outflows from supermassive black holes (SMBH) may play a significant role in the evolution of galaxies.
The observations made with the ESA XMM-Newton space telescope on the black hole located in the heart of the active Pg 1114 + 445 galaxy, showed how ultrafast winds interact with interstellar matter near the center of the galaxy. These ultrafast winds coming out of the black hole are called outflows of gases emitted by the accretion disk, in the region near the black hole itself, in the vicinity the event horizon.
The study of the data was carried out by a team of scientists led by Roberto Serafinelli of the Italian National Institute of Astrophysics and showed how supermassive black holes model their host galaxies with powerful winds that sweep away interstellar matter and slow down the rate of formation of new stars.
Serafinelli says: «We observe, for example, a correlation between the masses of supermassive black holes and the dispersion of speed of the stars present in the inner regions of the host galaxies. However, this cannot be due to the gravitational attraction of the black hole, due to the high distance of the gas from it. Our study, for the first time,
