Universe’s giant early galaxy reveals secrets of supermassive black holes

Science News Desk – Black holes are no longer a mystery, they are no longer a fact. Yes, there can be a dispute on this because many scientists believe that whatever we know about black holes may not be small in quantity, but it is much less than the possible complete knowledge of black holes. Now astronomers have discovered a supermassive black hole in a massive galaxy in the early universe. The discovery of this galaxy and black hole could provide insight into how the earliest supermassive black holes formed.

a big secret
The study, by astronomers from the University of Texas and the University of Arizona, has been published in the Monthly Notices of the Royal Astronomical Society. The biggest mystery of supermassive black holes so far is how the supermassive black holes formed at the beginning of the universe, which are believed to take a long time to grow.

star formation rate
In this study, astronomers, using observations from the Atacama Large Millimeter Array (ALMA), a radio observatory in Chile, discovered a supermassive black hole called COS-87259 with a star formation rate comparable to that of our Milky Way. It is a very large galaxy. a thousand times more.

Even more special is the black hole of the Galaxy
Apart from this, the special thing about this galaxy is that it has interstellar dust of billions of solar weights. Due to the process of such rapid star formation and very fast growing black hole, this galaxy is shining very brightly. This black hole is a new type of primordial black hole which is covered by celestial dust. Due to which the light emitted from it becomes mid-infrared range in the electromagnetic spectrum.

confounding factor
The researchers also found that this growing supermassive black hole, sometimes called an active galactic nucleus, is producing a powerful jet of matter at nearly the speed of light. Today’s black holes, which are hundreds of billions of times more massive than our Sun, are found at the center of almost every galaxy. And it’s surprising to find such a large supermassive black hole in the young universe.

how long after the big bang
Because the light from these sources takes so long to reach us, we see it as it appeared at the same time. So this galaxy and black hole are 750 million years after the Big Bang, which is only 5 percent of the present age of the universe. Even more shocking is that this body has appeared behind a small part of the space.

There may be other sources
This clearly means that there could be many such sources in the early universe and was completely unexpected for the researchers compared to the data so far. Apart from this, other types of supermassive black holes that have been known in the early universe are called quasars. These active black holes are not surrounded by dust, but are much smaller than the extent of COS-87259. The discovery of COS-87259 and its black hole has raised many questions about the existence of so many supermassive black holes in the early universe.

The existence of such a body had been predicted before, but it has now been observed. Such objects are not surprising today, but the discovery of COS-87259 and its black hole could help increase our understanding of how black holes of billions of solar masses formed so quickly in the universe, and how many Massive galaxies can grow so quickly.
