- Phase-space Structure of the Milky Way's Dark Halo
- Time: 2:30 pm - 3:30 pm
- Place: 5280 Chamberlin Hall
- Speaker: Leanne Duffy, Los Alamos National Laboratory
- Abstract: Abstract: The evolution of cold dark matter in phase-space inevitably leads to high density regions in physical space, known as caustics. The significance of these high density structures is a current topic of debate. One interesting possibility is presented by the caustic ring model, which describes the accretion of dark matter onto galactic halos. I explain the formation of dark matter caustics, present an overview of the caustic ring model and predictions of the model for the Milky Way halo. The resulting dark matter flows and overdensities may have important consequences for both direct and indirect dark matter detection experiments.

- New oscillation results from MiniBooNE
- Time: 4:00 pm
- Place: 4274 Chamberlin
- Speaker: Chris Polly, University of Illinois Urbana-Champaign
- Abstract: In June 2007, MiniBooNE published results for a search for electron flavor neutrinos appearing in a predominantly muon neutrino beam. Although no excess of events was observed at an L/E consistent with a simple mixing interpretation of LSND, a > 3 sigma excess was observed at low energy. In the intervening time, MiniBooNE has acquired 3.3e20 POT delivered with the horn-focusing positively charged pions to create a predominantly antineutrino beam. The results from the recently unblinded nuebar appearance search will be discussed along with work that has transpired over the last year in understanding the low energy excess.
