Given the extreme temperature and pressure that is presumed to exist
in a quasar, is it really surprizing that they have metal lines in
their spectra?  Couldn't they fuse lighter elements into metals?  I've
heard quasars described as being the size of our Solar System but
emitting more energy than a galaxy.
