TL;DR: The AMANDA-II data collected during the period 2000-2003 have been analysed in a search for a diffuse flux of high-energy extra-terrestrial muon neutrinos from the sum of all sources in the Universe as mentioned in this paper.

TL;DR: Measurements in the 300-900 MHz range are presented, which are the first self-triggered, first ultrawide band, first far-field, and the highest energy sample of cosmic ray events collected with the radio technique.

TL;DR: In this paper, a power spectrum analysis was performed on the relative intensity map of the cosmic ray flux in the southern hemisphere, and it was shown that the arrival direction distribution is not isotropic, but shows significant structure on several angular scales.

TL;DR: A fourth steeply upward-pointing ANITA-I CR-like radio event which has characteristics consistent with a primary that emerged from the surface of the ice suggests a possible τ-lepton decay as the origin of this event, but such an interpretation would require significant suppression of the standard model τ-neutrino cross section.

TL;DR: An upward traveling, radio-detected cosmic-ray-like impulsive event with characteristics closely matching an extensive air shower is reported on in the third flight of the ANITA, a NASA-sponsored long-duration balloon payload.
