Thanks to the technological capabilities of the Chandra and Wise space telescope, we have the opportunity to observe the collision of two black holes trapped in their home galaxies. Explanations

What do you think would happen if two black holes collided? Certainly a cosmic event so powerful that it shouldn’t be missed for the world, right? Well, here it iswe wish you good observation!

Black holes collide with each other
This is a first in the history of astronomy. After M87 sightingsthe supermassive black hole at the heart of its namesake galaxy (these incredible cosmic objects are definitely the talk of the town these days), here’s a photo proving the existence of two dwarf galaxies, both hosts of colliding black holes.
The first system is here the Abell 133 cluster, about 760 million light-years away our earth. The other dwarf galaxy lies within the galaxy cluster Abell 1758S, 3.2 billion light-years from us.
New insights into the early universe
This particularly complex observation was made possible by the work of several astronomers. The latter hope to learn more about the primitive universe, a time when such events were much more common in our space.
“Astronomers have found many examples Black holes collide with relatively nearby large galaxies“But the search for these black holes in dwarf galaxies is much more difficult and has so far failed,” says Marko Micic, an astrophysicist at the University of Alabama and responsible for the study.
Two pairs of supermassive black holes in dwarf galaxies are on a collision course, in a new study from @ChandraXray. Researchers suspect that dwarf galaxies are merging into larger galaxies like our Milky Way and may offer glimpses into our galaxy’s past: https://t.co/TVjluH5Koa pic.twitter.com/omYsDnyHiU

A masterpiece of astronomy
At least until now! The main difficulty of such an observation was the size of these systems, which made their observation very complex. Since the latter emit little light, they are difficult to spot. And with good reason: they have very few stars.
In short, the combined efforts of the Chandra and Wise Space Telescope X-rays have found some signals attributed to black hole radio waves. researcher finally christened the merger with one and the same name: Mirabilis.
Astrophysicist Olivia Holmes says, “Using these systems as analogies to those in the early Universe allows us to go deeper.” Questions about the first galaxiestheir black holes and collisional star formation,” she explains.
