Maybe a little background reading. (No I don't have an immediate
answer, but I know that the dark halos are implicitly part of the
process that produces the visible light halos)
The Max Stirner approach: Why rely on other people to do it for you
when using your own brain is infinitely more satisfactory ...
astro-ph is a wonderful tool for cutting-edge research. The Los Alamos
XXX server, in general, should be used, OFTEN, especially for physics
related topics here.
For all: If any of you are concerned with keeping the list discussion
of high quality, and are interested in building a reputation whose
words carry some weight, then spending some time in background reading
and researching is an excellent idea. (For example I would never never
NEVER post on sci.astro.research or sci.physics.research, without
spending a considerable amount of time checking that what I wrote was
as correct as I could make it. My words are forever on usenet. There
is no difference on this list either.)
As an example on this dark matter halo topic.
Go to
http://xxx.uni-augsburg.de/find/astro-ph
(the mirror in my neck of the woods)
Select 'astro-ph' for Archive
Select 'past year' for Year
Select author/title/abstract for Search
Type 'dark matter halo' for word/pattern
Keep the defaults
Press the button: 'Do Search'
And.. voila! Thirty-one juicy papers to synthesize and learn about
dark matter halos ...
