Hi DA,

Ballantyne and crew have been doing some very interesting work concerning AGNs (active galactic nuclei.) I believe that AGNs will turn out to be very important to cosmologist and astrophysics. Perhaps some youngster will find a connection between these objects and, say, dark matter.

Here is a link to Ballantyne's pages at U of A:

Many of his publication can be had there.
