UD's Gaisser to present Sept. 25 colloquium on detector, cosmic neutrinos


4:04 p.m., Sept. 18, 2013--Thomas Gaisser, Martin A. Pomerantz Chair of Physics and Astronomy at the University of Delaware, will present the colloquium “Cosmic Neutrinos and Cosmic Particles in IceCube” on Wednesday, Sept. 25, in 104 Gore Hall.

The presentation, which will begin with a slide show at 3:30 p.m. followed by the talk at 4, is open to the University community and to the public.

IceCube is a kilometer-scale telescope embedded over a mile deep in the ice at the South Pole consisting of 5,400 optical sensors that detect cosmic rays and neutrinos. 

Research Stories

Patched atoms

Dion Vlachos has published a paper in Nature Communications showing that a patched architecture may yield more effective catalysts than a traditional core-shell structure.

Research symposium

Twenty-eight UD students competed at a recent Undergraduate Research Symposium in the Chemical and Biological Sciences, with nine receiving first-place awards and six receiving second-place awards.

This unique telescope in the ice recently discovered the first evidence for neutrinos of high energy from extraterrestrial sources.

Gaisser will review the data and explain the significance of such a discovery during his talk. 

He also will show slides of IceCube construction from 2003-10. Members of the IceCube group in the UD Department of Physics and Astronomy played a major role in the detector’s construction, particularly its surface array of sensors, called “IceTop,” and continue to be involved in its operation and analysis.
