Astronomers have noticed how a black hole “raises” the stars in a nearby dwarf galaxy; In addition, newborn stars are attached to a black hole by a massive “umbilical cord” of gas and dust.
A supermassive black hole about 34 million light-years from us is located in the galaxy Henry 2-10. Astronomers have noticed that from the center it emits a huge, 500 light-year ionized gas cannon at a speed of 1.6 million km / h; As a result, it creates a “fiery storm” of star formation in nearby stellar incubators.
The discovery was made by NASA’s Hubble Space Telescope and is the first time we have seen how a black hole raises stars in a dwarf galaxy with less than a billion stars in total.
“I knew from the beginning that something unusual and special was happening at Henry 2-10, and indeed, Hubble gave us a very clear picture of the connection between the black hole and the star-forming region 230 light-years away. “Hubble’s stunningly high-resolution images show body-like characteristics in gas motion, which fits in with the model of the oscillating drain from a black hole,” said study co-author Amy Raines, an astrophysicist at Montana State University.
Astronomers have noticed how thin cannonballs stretch from a black hole to stellar incubators. Millions and billions of solar masses gather in supermassive black holes; Space cannons erupted from them have been observed before, but astronomers until now thought that in dwarf galaxies they did not even contribute to the formation of stars, on the contrary, they slowed down the process.
“Henny 2-10 is just 30 million light-years away from us, which is long enough for Hubble to take very clear pictures and gather clear evidence of a black hole leaking. “An additional surprise was that instead of suppressing star formation, this flow causes new stars to be born,” said study author Zachary Shatt, an astronomer at the University of Montana.
Black holes absorb matter from nearby gas clouds and stars, and then some of it, in the form of ignited plasma, is fired back at almost the speed of light back into space. When heated to the appropriate temperature, the gas cloud that comes in contact with this cannon will become the ideal incubator for future stars.
However, if the cannon overheated the gas clouds, they could no longer cool to the temperature required for star formation; But the 2-10 black hole cannon on the henna is less massive, relatively soft, and therefore in the gas encountered on the way it creates ideal conditions for the birth of stars.
Since this black hole has not grown over time and remains relatively small, researchers believe that studying it in more detail will help us understand how supermassive black holes grow to colossal proportions. In addition, to study black holes like it, it is already possible to use the high-resolution method created by a team of researchers to notice the unnoticed handwriting of black holes.
“We do not see the first black hole era now, and therefore there is one big question: where did they come from? “Dwarf galaxies may still hold black hole conception scenarios that are already lost elsewhere in time and space.”
