New IceCube analysis sets upper limits on time-dependent neutrino sources

The IceCube Collaboration searches for neutrino sources using a variety of analysis methods. In a paper submitted yesterday to The Astrophysical Journal, the collaboration describes a time-dependent all-sky scan using five years of IceCube data as well as a specific analysis of blazar 3C 279. The analyses did not reveal any new neutrino point sources. […]

Can a high-energy neutrino detector see low-energy neutrinos?

In a paper submitted recently to JCAP, the IceCube Collaboration describes a search for sub-TeV neutrino emission from astrophysical “transient” sources. This is the first transient result from IceCube to use all neutrino flavors in the 1-100 GeV energy region. In the absence of any observed sources in three years of archival IceCube data, the researchers established new limits on the volumetric rate of transients. […]

IceCube performs new measurement of all-flavor neutrino cross section

The number of neutrinos that IceCube detects is dependent on many factors, including the “neutrino cross section”: how likely it is for neutrinos to interact with nuclei in the ice. In a paper submitted today to Physical Review D, the IceCube Collaboration reports a new cross section measurement obtained by using 7.5 years of IceCube data. This is the first such measurement to incorporate all three neutrino flavors. […]

IceCube at holiday light display in Madison, WI

The Wisconsin IceCube Particle Astrophysics Center (WIPAC), a research center that is part of UW–Madison’s Office of the Vice Chancellor for Research and Graduate Education and headquarters for the IceCube Neutrino Observatory, is sponsoring its first display for the 32nd annual Holiday Fantasy in Lights event in Madison, Wisconsin, USA. The lights are on every […]
