The reason of inexplicable death of galaxies is found


The international group of scientists has found a new explanation for why some galaxies die without the visible reasons, that is in them processes of formation of stars completely stop. According to conclusions of astronomers, it occurs because the star wind proceeding from dense congestions of stars blows all gas from the galaxy. Article of researchers is published in The Astrophysical Journal. According to a traditional hypothesis, galaxies can lose gas, necessary for star formation, because of an active kernel which marks out huge amount of energy because of the eating supermassive black hole. However in 2007 astronomers have found galaxies in which stars weren't born, but at the same time there were no signs of existence of active kernels in them. Researchers have studied these galaxies by means of Hubble Space Telescope and have found out that they differ in huge star density. They are so massivna as the Milky Way, however all their weight is concentrated in the area with a diameter about one thousand light years. Such dense arrangement of stars creates a powerful stream of the particles which are beating out gas molecules on intergalactic Wednesday. As a result from the galaxy all substance necessary for the birth of new stars disappears. It is more than important news in Film of Day Telegram-channel. Subscribe!
