Detecting the supermassive black hole is spraying material

Scientists use NASA's Chandra X-ray telescope to detect a supermassive black hole in the center of a nearby galaxy.

This black hole seems to be "spraying" material, after draining all the material near it. This phenomenon may have contributed to the formation of the early universe.

New research results of scientists have been presented at the meeting of the American Astronomical Society (AAS) in Florida on January 5, and published in the Astrophysical Journal near. here.

According to the study, scientists discovered that a black hole is spewing out two glowing gases and matter, near the center of NGC 5195 , a small galaxy located from our galaxy (Milky Way). ) about 27 light years. This galaxy is in the process of merging with another galaxy, named NGC 5194 , creating a large spiral in the universe.

Astronomer Eric Schlegel at the University of Texas (USA) said at the meeting of AAS: " We think this happens very often in the early universe . At that time the galaxies are" crowded ". At high density, they often collide and you will see the air gushing out like this. "

Schlegel said that these light streams were created from materials that were thrown during the merger of the two galaxies.

In a related study, scientists also discovered a supermassive black hole that stars surrounding it might be attracted to a companion black hole. This black hole pair, located about 1 billion light-years from the Solar System, is located in the SDSS galaxy J1126 + 2944.

This pair of rare black holes (belonging to one of the 12 galaxies known to contain two supermassive black holes) is most likely the result of two merging galaxies, astrophysicist Julie Comerford at the University. Colorado, Boulder, said at the AAS conference.

Scientists are investigating why a black hole in this "couple" has a number of stars around 500 times less than its companion.

A black hole (or black hole) is an area in outer space where its attraction prevents everything, even light cannot escape. General relativity suggests that a large enough mass of matter within a small enough range will distort the space-time to become a black hole. In theory, black holes can form from the collapse of very massive stars in their final stages. After forming, the black hole continues to attract matter from the surrounding space, and its mass increases gradually over time.
