... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

Weak Lensing Constraints on Dark Matter Halos Tereasa Brainerd Institute for Astrophysical Research, Boston University, USA It is currently thought that all large galaxies reside within massive dark matter halos. Despite the apparent ubiquity of such halos and their importance for developing a complete picture of the history of galaxy formation, the characteristic parameters (e.g., total mass, physical extent, and shape) of these objects remain largely unconstrained at present. ...
