IceCube - status and recent results

Understand

In May 2011, the IceCube neutrino observatory with one cubic kilometer instrumented volume started full operation with 5160 sensors on 86 strings and 324 sensors on 162 IceTop detectors.

• The fine-tuning of operation and calibration of the detector is still in progress while a very high uptime of well above $98\%$ is obtained.
• New analysis techniques rely on veto techniques for enhanced rejection of atmospheric muon and neutrino backgrounds.
• We will give an overview of recent results including the techniques of searching for starting tracks and some comments on the reported evidence of astrophysical neutrinos at energies above 30 TeV.
