The powerful energy emitted by black holes creates a galactic-scale stream of gas that destroys the interstellar medium that makes up stars.
Researchers using the Atacama Large Millimeter / Submillimeter Wave Array (ALMA) discovered a giant galaxy wind (HSC J124353.93 + 010038.5) caused by a supermassive black hole 13.1 billion years ago. A detailed analysis of the ALMA data revealed that it has a high-speed gas flow traveling at 500 km / s. This stream of gas has enough energy to drive stellar matter away from the galaxy and stop star-forming activity.
This is the oldest example of a wind of this type ever observed, as it is happening less than 1 billion years after the birth of the universe and evidence that a huge black hole has had a significant impact on the growth of galaxies since the beginnings of the history of the universe.
Astronomers believe that galaxies and black holes have grown and evolved together (coevolution) through some physical interaction and galactic winds can provide this type of physical interaction between black holes and galaxies.
Supermassive black holes swallow large amounts of material. When the gravity of a black hole causes the material to move at high speed, it emits strong energy that can push the surrounding material outward. This is how the galactic wind is generated.
“We plan to observe many of these objects in the future, and would like to clarify whether the primitive coevolution seen in these objects is an accurate picture overall. space at that time ”, explain the authors.
