Performance of the X-Calibur Hard X-Ray Polarimetry Mission during its 2018/19 Long-Duration Balloon Flight
Quincy Abarr, Banafsheh Beheshtipour, Matthias Beilicke +28
X-Calibur is a balloon-borne telescope that measures the polarization of high-energy X-rays in the 15--50keV energy range. The instrument makes use of the fact that X-rays scatter…
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)
R. Prechelt, S. A. Wissel, A. Romero-Wolf +65
We study in detail the sensitivity of the Antarctic Impulsive Transient Antenna (ANITA) to possible point source fluxes detected via -lepton-induced air showers. This inve…
XL-Calibur -- a second-generation balloon-borne hard X-ray polarimetry mission
Q. Abarr, H. Awaki, M. G. Baring +38
XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission,…
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…
Unusual Near-horizon Cosmic-ray-like Events Observed by ANITA-IV
ANITA Collaboration, P. W. Gorham, A. Ludwig +57
ANITA's fourth long-duration balloon flight in late 2016 detected 29 cosmic-ray (CR)-like events on a background of anthropogenic events. CRs are mainly seen…
Observations of a GX 301-2 Apastron Flare with the X-Calibur Hard X-Ray Polarimeter Supported by NICER, the Swift XRT and BAT, and Fermi GBM
Q. Abarr, M. Baring, B. Beheshtipour +28
The accretion-powered X-ray pulsar GX 301-2 was observed with the balloon-borne X-Calibur hard X-ray polarimeter during late December 2018, with contiguous observations by the NICE…
