Hitekno.com – How to measure Supermassive black hole, The shape alone is difficult to notice. Para Astronomer Apparently a new way to do it has been found.
Astronomers find new way to calculate size Black hole Supermassive, namely by studying the diet of this giant object.
Scientists have long observed luminous patterns in the brightness of accretion disks, as matter is pulled up by the black hole’s gravitational force.
However, astronomers and experts do not know what caused the glowing pattern in the supermassive black hole.
Now, a team of astronomers has determined that the disk’s accumulated luminosity is related to the mass of the black hole inside.
“We believe the same technique applies to many things, such as objects smaller than black holes.said Yu Shen, principal professor and study astronomer at the University of Illinois Arbana-Champaign.
To study the relationship between the size of the supermassive black hole and the light emitted from the disk, scientists selected 67 supermassive black holes.
Each previously estimated mass is between 10,000 and 10 billion times the mass of the Sun.
When the data showed a correlation, the researchers decided to look at a very small object with a white dwarf’s accretion disk.
“Now there is a relationship between the blinking method and the charging of the central accretion object,” said Colin Burke, a professor of astronomy and graduate student at Arbana-Champaign University in Illinois.
He said this could be used to predict what a glowing signal from an intermediate black hole would look like.

This is a new way for astronomers to measure supermassive black holes by observing their glowing shape. (Suara.com/ Lintang Siltya Utami).
