Ultrafast star escapes black hole

"Galactic nuclei are the cores of galaxies, groups of thousands to millions of stars that are held together by gravity. As stars in the nucleus are so close together, interactions readily occur. If ultraheavy black holes (black holes several million times heavier than the sun) are also involved, stars can be slung out of the galaxy (for example the Milky Way) at speeds of more than one thousand kilometres per second."

I'm not sure how many times this has actually been observed... I wouldn't mind having some of those super computers though, I have a lot of research I'd like to do myself...
