Astronomers made a remarkable discovery: Supermassive Black Hole two active quasars were found in an early galaxy. The two supermassive quasars are only 10,000 light years apart and on a collision path with each other.
Discovering an Ancient Binary Quadrasar in Early Universe
Scientists can better understand black holes’ evolution by studying this upcoming cosmic collision, J0749+2255.
According to Science Alert‘s article, galaxy mergers occur frequently, but spotting binary quasars is extremely unlikely, especially when they are so close together.
J0749+2255: A Glimpse into the Primordial Universe
The discovery of double quasar J0749+2255 represents an essential stage in understanding the evolution of black holes supermassive.
This rare image was taken just 3 billion light years after the Big Bang. It contains two supermassive, actively feeding black holes on a collision path, separated by only 10,000 light-years.
Uncovering the secrets of supermassive black hole growth
Scientists have used observations from ground- and space-based telescopes to determine that in 220 million years, the two black holes will evolve into a tightly bound binary and then merge into an even larger black hole.
Scientists could use this information to solve the puzzle of how black holes can grow so massive. The two black holes within J0749+2255 have a mass of around 1,26 and 1.58 billion solar masses, respectively. This could show how binary supermassive-black holes formed in the early Universe.
Double Quasar Galaxies: A Rarer Sight
Researchers must study more double-quasars to understand their evolution. In the early Universe, single quasars were quite common due to galaxies combining.
Twin quasars, on the other hand, are rarer and more difficult to detect because the space between two black holes is too small to be seen by our instruments. The Gaia telescope detected a slight variation in the light coming from the galaxy, which led to the discovery of J0749+2255.
A new method to more easily identify early universe double Quasar galaxies
The difficulty distinguishing these two quasars may stem from their similar combined radiative powers. The two quasars are also redshifted similarly, making them difficult to determine if they are not the same object.
Researchers have developed a way to identify these galaxies more efficiently and plan to use it to find more double quasars in the early Universe. This study is available in full on Nature, where it was initially published.
J0749+2255: Discovering the Origins of Supermassive Black Holes
Astronomer Xin LIU of University of Illinois at Urbana Champaign revealed what they spotted. The researchers said the discoveries were just the tip of the iceberg.
J0749+2255 represents a significant advance in the study of supermassive Black Holes. Scientists may be capable of using this information shortly to improve our understanding of black holes’ evolution.
