Sigma

Everyday I go to work, I don't really know what's going to happen, but I can count that it's going to be something exciting every single day.
These past six months have been phenomenal in terms of black hole research. We've been extremely excited we were finding these black holes in, in, in numbers that we had never been able to do before.
Karl Gebhardt and Laura Ferrarese were trying to find the fundamental connection linking black holes and their galaxies. So they searched through all the different galaxy characteristics, looking for any new links that might give a clue. But it wasn't until they looked at the property called sigma that the mystery began to unravel.
Sigma is just a very, very fancy name for something that's actually very simple.
Sigma is the speed at which the stars are circling in the outer reaches of the galaxy. The stars at the edge of the galaxy are so far away from the black hole that they are completely unaffected by its gravity.
