elliptical galaxy

Published by a team of American scientists in The Astrophysical Journal, the study analyzes "one of the most massive black hole systems known," a binary located within the elliptical galaxy B2 0402+379.

National Science Foundation, to analyze a supermassive black hole binary located within the elliptical galaxy B2 0402+379.

The mass of the black hole is also correlated to the stellar mass of a spiral galaxy's central bulge, or the overall mass of an elliptical galaxy.

The researchers studied an exotic object called a blazar at the center of a large elliptical galaxy named Markarian 501 located about 460 million light years away from Earth in the direction of the constellation Hercules.

But because both reside near a massive elliptical galaxy, called NGC 1052, the explanation may be simple: their dark matter could have been “tidally stripped” away by the gravity of this humongous companion, leaving behind only the normal matter.
