Prof Subir Sarkar

The IceCube project at the South Pole (not the rapper) transformed a cubic kilometer of transparent natural Antarctic ice into a Cherenkov detector that observes neutrinos from GeV to PeV energies. This experiment discovered very high energy cosmic neutrinos and identified the first likely cosmic sources, the blazar TXS 0506+056 and the active galaxy NGC 1068. IceCube is a multipurpose research facility which has also made precision measurements of neutrino oscillations and made important contributions to cosmic ray physics, dark matter searches, and glaciology.

The University of Oxford (Institution Lead: Prof Subir Sarkar) has been a full member of the IceCube collaboration since it was formed in 2004. Oxford Physics hosted the first Collaboration Workshop in 2005
