Astronomers Find 83 Supermassive Black Holes in Early Universe


Astronomers from Japan, Taiwan and Princeton University came together to find nearly 83 quasar bursts, which are from the black holes that were formed in the early age universe. According to the astronomers, these quasar bursts are from the time, when our world was 10 percent of its current age which is billions of years ago. Michael Strauss, a professor of astrophysical sciences at Princeton University noted that this is very astonishing to see black hole formation in early age universe when everything was in its first stage.

The research and deductions done by astronomers from Japan, Taiwan and Princeton University were published in The Astrophysical Journal and the Publications of the Astronomical Observatory of Japan. The research indicates the formation of the black holes in a first billion years when almost everything was in the gaseous state, and the stars and galaxies were forming. The discovery is of the supermassive black holes and not the typical black holes. The supermassive black holes are billion times heavier in mass and emit high-energy radiation in space named as “Quasars”. Using the quasar illumination, the scientists found these supermassive black holes formed in a first few billion years.

The astronomers used the high-end instrument dubbed as “Hyper Suprime-Cam”, which is mounted on the Subaru Telescope in Hawaii. The Hyper Suprime-Cam has the field of view of 1.77 degrees across. The astronomers study nearly 300 nights for over five years to conclude the research and understand the origin of the quasar sources. At first, the astronomers used the HSC survey data to shortlist some of the quasar sources and then did an intensive study campaign to understand the spectra of these quasar sources. As these quasars are 13 billion light years away, we are seeing back in the time. Also, we are just 800 million light years away from the big bang, as scientists think Big Band happened nearly 13.8 billion years ago.
