One crucial component of our current understanding of galaxies and cosmology is that most of the matter in the Universe is in the form of dark matter--an as-yet-unidentified form of matter that appears to neither give off nor interact with light. In this talk, Professor Bell will describe what we have learned about the distribution of dark matter around galaxies by studying stars in the sparsely-populated distant outskirts of galaxies, well outside where one would expect to find stars.
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from Weiser Hall (formerly the Dennison Building) in the U-M Church Street parking structure. There is a $2.00 parking charge implemented by U-M Parking Services. For more information regarding the Saturday Morning Physics series, click here, or call 734.764.4437.
