L. Cremonesi, A. Connolly, P. Allison +57
A Monte Carlo simulation program for the radio detection of Ultra High Energy (UHE) neutrino interactions in the Antarctic ice as viewed by the Antarctic Impulsive Transient Antenn…
A search for ultrahigh-energy neutrinos associated with astrophysical sources using the third flight of ANITA
C. Deaconu, L. Batten, P. Allison +60
The ANtarctic Impulsive Transient Antenna (ANITA) long-duration balloon experiment is sensitive to interactions of ultra high-energy (E > 10^{18} eV) neutrinos in the Antarctic ice…
Constraints on the ultra-high energy cosmic neutrino flux from the fourth flight of ANITA
P. W. Gorham, P. Allison, O. Banerjee +57
The ANtarctic Impulsive Transient Antenna (ANITA) NASA long-duration balloon payload completed its fourth flight in December 2016, after 28 days of flight time. ANITA is sensitive…
Constraints on the diffuse high-energy neutrino flux from the third flight of ANITA
P. W. Gorham, P. Allison, O. Banerjee +57
The Antarctic Impulsive Transient Antenna (ANITA), a NASA long-duration balloon payload, searches for radio emission from interactions of ultra-high-energy neutrinos in polar ice.…
Upward-Pointing Cosmic-Ray-like Events Observed with ANITA
Andres Romero-Wolf, P. W. Gorham, J. Nam +73
These proceedings address a recent publication by the ANITA collaboration of four upward- pointing cosmic-ray-like events observed in the first flight of ANITA. Three of these even…
Observation of an Unusual Upward-going Cosmic-ray-like Event in the Third Flight of ANITA
P. W. Gorham, B. Rotter, P. Allison +60
We report on an upward traveling, radio-detected cosmic-ray-like impulsive event with characteristics closely matching an extensive air shower. This event, observed in the third fl…
Antarctic Surface Reflectivity Measurements from the ANITA-3 and HiCal-1 Experiments
P. W. Gorham, P. Allison, O. Banerjee +53
The primary science goal of the NASA-sponsored ANITA project is measurement of ultra-high energy neutrinos and cosmic rays, observed via radio-frequency signals resulting from a ne…
Characteristics of Four Upward-pointing Cosmic-ray-like Events Observed with ANITA
P. W. Gorham, J. Nam, A. Romero-Wolf +66
We report on four radio-detected cosmic-ray (CR) or CR-like events observed with the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload.…
Analysis of a Tau Neutrino Origin for the Near-Horizon Air Shower Events Observed by the Fourth Flight of the Antarctic Impulsive Transient Antenna (ANITA)
