Constraints on the Extremely-high Energy Cosmic Neutrino Flux with the IceCube 2008-2009 Data

We report on a search for extremely-high energy neutrinos with energies greater than 10⁶ GeV using the data taken with the IceCube detector at the South Pole. The data was collected between April 2008 and May 2009 with the half-completed IceCube array. The absence of signal candidate events in the s...
