Since this is not my area of expertise, I searched Google under the key words "<I>galaxy formation</I>" to get these possible sources:
http://en.wikipedia.org/wiki/Galaxy_formation_and_evolution
http://abyss.uoregon.edu/~js/ast123/lectures/lec25.html
http://imagine.gsfc.nasa.gov/docs/teachers/galaxies/imagine/page22.html
http://zebu.uoregon.edu/1996/ph123/galaxies.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.
I hope this helps. thanks for asking.
