Starburst Galaxies Formation and Facts Starburst galaxies form stars much faster than normal galaxies. They can create new stars 1,000 times faster than regular galaxies. They are triggered when two galaxies pass by each other. Other ways that they can be created include galactic merging and if the galaxy has a galactic bar. All galaxies have a black hole in their center, and when they are extremely active, this can trigger rapid star formation. The dust and gas supply in starburst galaxies is used up quickly to form a lot of new stars. Once starburst galaxies start, they end not long after. Starburst galaxies can occur anywhere, but mostly happen near the nucleus of the galaxy. Starburst galaxies can sometimes be the brightest things in the universe. This happens when they release ultraviolet rays, which are absorbed by the dust and then re released at infrared wavelengths. The formation of stars can be stopped if the remaining gas in the galaxy is blown away by stellar winds or a Supernova explosion. Starburst galaxies are less common now than they were in the early stages of the universe. These galaxies are about 12 billion…show more content…
Specific types of the starburst galaxies include Wolf-Rayet galaxies, Blue compact galaxies, and Luminous infrared galaxies. Wolf-Rayet galaxies are classified by their ratio of bright stars that happen to fall under the Wolf-Rayet classification. Blue compact galaxies are the result of mergers because they appear to be somewhat new galaxies, but they also have a few older stars inside them. The merging of two galaxies is the only way to explain how this is possible. Infrared radiation is used to examine luminous infrared galaxies. The infrared radiation uses dust to determine if there has been a lot of recent star formation. Like blue compact galaxies, these galaxies can also be formed by mergers. However, luminous infrared galaxies can sometimes have supermassive black
