Organized by Chuck Horowitz
Welcome to an informal physics journal club on Weds. at 12:15 in the Tea Room, Swain West 113. All are welcome. The Journal club presents recent results and covers a very wide range of topics. Feel free to suggest topics, articles, or speakers or to volunteer to help present a talk. Please send comments via email to horowit "at" indiana.edu or phone 812 855-2959 or 812 855-0303. Presentations should be short and simple and not require much preparation. Please let me know if you would like to be involved and give or help with a presentation! All are welcome!
FREE PIZZA will be available! Please come for the food and for the good discussion.
Talks should be self-contained and accessible to a beginning Physics graduate student.

Here's additional work by another group:
Finally, here's a press release by the Max-Planck Institute for Plasma Physics who are also studying this method:

Feb. 28 A direct empirical proof of the existence of dark matter (Bob Armstrong and John Urheim)
Gravitational lensing can reveal the distribution of dark matter. For one colliding cluster of galaxies the distribution of dark matter is very different from the distribution of normal matter!
Merging galaxy cluster 1EO657-558. The green contours are the distribution of dark matter as deduced from gravitational lensing while the other colors show the visible matter as seen in X-rays.
