Discovered 16 ancient super black holes bombarding the universe

A team of astronomers has investigated where powerful beams from these 10 billion year old black holes have been and are heading .

According to NASA's news site, using NASA's Chandra X-ray Observatory , the US National Science Foundation's (NSF) National Radio Astronomy Observatory (NRAO ) and the Very Large Baseline Array (VLBA) , an international team of scientists observed 16 raging black holes .

They are all monster black holes at the center of galaxies.

Unlike the hibernating monster Sagittarius A* of the galaxy containing Earth, the Milky Way (Milky Way), the 16 black holes mentioned above are still strongly swallowing matter and shooting terrible streams of matter throughout space.

In new research, a US-Italian research team led by Dr. Francesco Ubertosi from the University of Bologna (Italy) even discovered that these black holes continuously change direction.

Publishing the above results in the scientific journal The Astrophysical Journal, the authors took as an example two black holes located in the galaxy cluster Abell 478 and the galaxy group NGC 5044.

Comparisons between the Chandra and VLBA images show that the beams of the monster midgut Abell 478 change direction by about 35 degrees, while the beams of the black hole midge NGC 5044 change direction by about 70 degrees.

In total, about one-third of the observed black holes have shown a visible change in direction.

Some have even changed direction by nearly 90 degrees in just a period of 1 million years to a few tens of millions of years. These black holes are about 10 billion years old, so this change in direction is relatively quick.

The beams that the black hole shoots into space are actually the "burp" products of its intense meals, often perpendicular to the plane of the black hole.

The change in direction that scientists have observed suggests that the black hole itself may have changed, thereby changing the angle at which these furious beams are fired into the universe.

While powerful and terrifying, these beams are not death after all.

They indeed pump strong energy into the inner region and center of the galaxy, causing the galaxy's hot gas to continuously burn, unable to cool.

But this has helped stimulate the star formation process and helped the galaxy grow.

On the contrary, if the black hole changes direction too much, the area it previously bombarded will no longer be heated as before, thereby slowing down the star formation process.

This discovery contributes to showing how central black holes affect the life of the galaxy in which they reside, as well as the surrounding space and possibly some neighboring galaxies in the same place. a cluster.
