On Tuesday, Sept. 8, the University of Maryland will launch a new university calendar that will streamline and replace the FYI and Free Stuff @ UMD calendars. Beginning Sept. 8, you will be able to submit your events to the new campus calendar for review and approval, much like the current process for FYI and Free Stuff @ UMD. On Sept. 8, if you visit this website, you will automatically be redirected to the new calendar. In addition, a new weekly email called UMD This Week will launch on Sept. 8, replacing the daily FYI email. UMD This Week will be delivered at the beginning of every week and will highlight top upcoming events. The email will include details on how to access the new calendar and how to submit events for approval. Questions? Email UMDevents@umd.edu.

Where: Computer & Space Science : Coffee, Tea & Cookies 4:15-4:30 PM : 2400

Structure formation in a nonlocally modified gravity model
We study a nonlocally modified gravity model proposed by Deser and Woodard which gives an explanation for current cosmic acceleration. By deriving and solving the equations governing the evolution of the structure in the Universe, we show that this model predicts a pattern of growth that differs from standard general relativity (+dark energy) at the 10-30% level. These differences will be easily probed by the next generation of galaxy surveys, so the model should be tested shortly.
