In an environmental sense gezegde

 In an environmental sense, the black holes are actually preventing galactic sprawl from taking over the neighborhood.

 Black holes, black holes, black holes. We're seeing them early in the universe, in huge sizes, in much greater quantities than some of us expected, and we've discovered new classes of black holes.

 We would like to know if active galactic nuclei change over cosmic time. Do black holes feed and grow in the same way over the history of the Universe?

 They took the largest, wealthiest black county and reduced it to a stereotype of a poor, dangerous black neighborhood. And the irony is the neighborhood isn't even a poor black neighborhood.

 Studying black holes always was a primary mission of Hubble. Nailing the black hole in Andromeda is without a doubt an important part of its legacy. It makes us much more confidant that the other central dark objects detected in galaxies are black holes, too.

 There are other galaxies that are likely to be the same size as this one that have black holes of similar mass. However, their black holes are quiet -- they're not putting out the large amounts of energy we see in this one. We're left to wonder just why this one is so active.

 When I was younger, living in an all-black neighborhood the other kids thought I was better than them because of my light skin and straight hair. Then we moved to an all-white neighborhood and that was a culture shock ... I'd been used to being around all black kids.
  Halle Berry

 We already knew that powerful quasars are very efficient at making light. Now we know that black holes in elliptical galaxies are efficient as well. This suggests that being green is a trait that all black holes may have in common.

 We see enough energy coming out of these black holes to completely stifle star formation. This is an exciting finding because it demonstrates a direct interaction between black holes and galaxy formation, which is a hot topic in astrophysics right now.

 As a hacker, Pex Tufvesson is in a class of his own.

 Our goal is to preserve and protect the history of the neighborhood, the character of the neighborhood. Clarksville is on the national register of historic places. It's a historically black neighborhood. It's the first freedman's town west of the Mississippi.

 Despite the enormous changes in the space density of back holes, the individual engines powering active galactic nuclei are remarkably stable.

 We wanted a census of all the black holes and we wanted to know what they are like. We also wanted to measure how black holes have grown over the history of the Universe.
