- Speaker: Markus Ackermann
- Abstract: Astrophysical results obtained by the Fermi Large Area telescope
mission in the first year of its mission are presented. In its first year the LAT has detected more than 10 million gamma-rays above 100 MeV and more than 1000 point sources, many of which were studied individually. These studies cover a wide range of astrophysical objects, like AGN, GRB, Starburst Galaxies, Pulsars, their Nebulae and Supernova Remnants. Besides individual objects, the properties of the diffuse emission from our own galaxy and beyond have been analyzed, yielding
new insights into the propagation of cosmic rays and the nature of the extragalactic diffuse emission. - Host: Albrecht Karle

- Search for active neutrino disappearance in MINOSSearch for active neutrino disappearance in MINOS
- Time: 4:00 pm

- Speaker: Brian Rebel, FNAL
- Abstract: MINOS is a long baseline neutrino oscillation experiment with two detectors<br>
separated by a distance of 735 km. The detectors are exposed to a high<br>
power muon neutrino beam originating at Fermilab. It has reported a<br>
significant deficit of muon neutrinos at its far detector relative to the<br>
near detector through measurement of the rate of charged-current<br>
interactions. If this deficit is due solely to conversions of muon-neutrinos<br>
to electron- and tau-neutrinos, then the rate of neutral-current (NC)<br>
interactions at the far detector remains unchanged from the non-oscillation<br>
prediction. Alternatively, if any muon-neutrinos convert to a sterile<br>
state, then the NC rate would be suppressed and the reconstructed energy<br>
spectrum would be distorted. In this talk I will describe the analysis of<br>
the NC interactions from an exposure of the MINOS detectors to 3.2 x 10^20<br>
protons on target. - Host: Matthew Herndon
