> Hello all, 
> 
> Tomorrow's summer seminar will be presented by Carsten Rott and Andrea Albert. The seminar will be held in the Cliffhanger Room of the Physics Research Building (PRB 4138) at 12:30 PM (note the non-standard time for the seminar). Below are the titles and abstracts for their talks.

> Precision physics with PINGU at the South Pole
> 
> The Precision IceCube Next Generation Upgrade (PINGU) is proposed as a new in-fill array for IceCube at the South Pole, Antarctica. The primary physics goal for PINGU is a determination of whether the neutrino mass hierarchy is normal or inverted using atmospheric neutrinos as the neutrino source. The determination of the mass hierarchy is one of the last unmeasured fundamental parameters in the neutrino sector. PINGU will also have an essential role in the search for low-mass dark matter and might enable us to probe the Earth interior by       exploiting matter effects in neutrino oscillations. I will summarize the status of PINGU and present high-lights of on-going sensitivity studies.

> Search for Spectral Lines with the Fermi Large Area Telescope
> 
> Recently a narrow spectral feature has been reported at 130 GeV localized in the Galactic Center. A gamma-ray spectral line is often considered a "smoking gun" for WIMP annihilations, so this would be a remarkable discovery if confirmed. However, the Fermi LAT Collaboration has searched for spectral lines from 5 to 300 GeV in 5 regions of interest and found no statistically significant (>3 sigma global significance) spectral lines. I will discuss what our search finds near 130 GeV and some of the systematic uncertainties we investigated that may induce false line-like features in our measured energy spectrum.
