"Black holes don’t have many identifying features. They come in one colour
(black) and one shape (spherical).
The main difference between black holes is mass: some weigh about as much as a
star like our Sun, while others weigh around a million times more. Stellar-mass
black holes can be found anywhere in a galaxy, but the really big ones (known
as supermassive black holes) are found in the cores of galaxies.
These supermassive behemoths are still quite tiny when seen in cosmic
perspective, typically containing only around 1% of their host galaxy’s mass
and extending only to a millionth of its width.
However, as we have just discovered, there is a surprising link between what
goes on near the black hole and the shape of the entire galaxy that surrounds
it. Our results are published in
Nature Astronomy."
