Search for neutrino point sources with IceCube 22-strings

Understand

The IceCube detector took data in its 22-string configuration in 2007-2008.

• This data has been analyzed to search for extraterrestrial point sources of neutrinos using several methods.
• Two main methods are discussed and compared here: the binned and the unbinned maximum likelihood method.
• The best sky-averaged sensitivity (90% C.L.) is E^2 Phi_nu_mu=1.3 10^-11 TeVcm^-2s^-1 to a generic E^-2 flux of nu_mu over the energy range from 3 TeV to 3 PeV.
