A University of Oklahoma doctoral student, graduate and undergraduate research assistants, and an associate professor in the Homer L. Dodge Department of Physics and Astronomy in the University of Oklahoma College of Arts and Sciences are lead authors on a paper describing a changing-look blazar - a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy. The paper is published in

Scientists at Ohio State University have discovered a record-breaking black hole. It is both one of the smallest black holes ever detected and the closest to Earth (1,500 light-years away and still inside the Milky Way galaxy).
“When we looked at the data, this black hole the Unicorn just popped out,” lead author Tharindu Jayasinghe, a doctoral student in astronomy at The Ohio State University, said in a statement.
Black holes cannot be seen, of course, but they can be detected by their corresponding stars. This black hole, dubbed the Unicorn because it is so rare and because it is located in the constellation Monoceros “The Unicorn, is only about three times the mass of our sun and is a companion to a red giant star.

Scientists have discovered what may be the smallest-known black hole in the Milky Way galaxy and the closest to our solar system - an object so curious that they nicknamed it the Unicorn .
The researchers said the black hole is roughly three times the mass of our sun, testing the lower limits of size for these extraordinarily dense objects that possess a gravitational pull so strong not even light can escape. A luminous star called a red giant orbits with the black hole in a so-called binary star system named V723 Mon.

Black holes form when massive stars die and their cores collapse.
