Finally, scientists figured out how gigantic the black hole is. Black hole rests in the center of the galaxy known as NGC 1332 and with the help of Atacama Large Millimeter/submillimeter Array (ALMA), the researchers managed to determine the mass of the black hole.
Black Hole's Magnitude
According to CSMonitor, the scientists suggested black hole's mass is 660 million times bigger than the sun's mass. The researchers, too, discovered the new way to gauge black holes with the level of accuracy found in ALMA.
The lead author of the study, Aaron Barth, said in the journal the Astrophysical Journal Letters published on Thursday that they had to get up close to the center of the galaxy to measure's black hole's mass. The location of the black hole has been known to have a great "gravitational pull" and ALMA served as the perfect device to compute black hole's greatness.
What Is ALMA?
ALMA is a unique kind of telescope situated far above in the deserts of Chile. ALMA possessed over 60 antennas that have the ability to detect the space's "millimeter and submillimeter" electromagnetic waves, Discovery News reported.
However, it is not the black hole ALMA exactly measured but, the outburst of galactic gases inside it. "To calculate the mass of a black hole in a galaxy's center, we need to measure the speed of something orbiting around it," Aaron Barth, who is also a professor at the University of California, Irvine, revealed.
How ALMA works?
Extreme Tech added that black hole is a huge oval galaxy roughly 73 million light years away from Earth. The most part of the galaxies have black holes in the middle although just one in ten elliptical galaxies has the measurable ones.
The rings of icy molecular mass and grime circling black hole are the ones letting it to be quantified correctly. It was the rotating current that can give black hole's real measurement that has been assessed by ALMA.
