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…
Antarctic Surface Reflectivity Calculations and Measurements from the ANITA-4 and HiCal-2 Experiments
S. Prohira, A. Novikov, P. Dasgupta +54
The balloon-borne HiCal radio-frequency (RF) transmitter, in concert with the ANITA radio-frequency receiver array, is designed to measure the Antarctic surface reflectivity in the…
HiCal 2: An instrument designed for calibration of the ANITA experiment and for Antarctic surface reflectivity measurements
S. Prohira, A. Novikov, D. Z. Besson +55
The NASA supported High-Altitude Calibration (HiCal)-2 instrument flew as a companion balloon to the ANITA-4 experiment in December 2016. Based on a HV discharge pulser producing r…
Dynamic tunable notch filters for the Antarctic Impulsive Transient Antenna (ANITA)
P. Allison, O. Banerjee, J. J. Beatty +56
The Antarctic Impulsive Transient Antenna (ANITA) is a NASA long-duration balloon experiment with the primary goal of detecting ultra-high-energy ($>10^{18}\,\mbox{eV}$) neutrinos…
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.…
