Abstract:

The first flight of the Antarctic Impulsive Transient Antenna (ANITA) experiment recorded 14 radio signals that were emitted by downward going cosmic-ray induced air showers. The dominant contribution to the radiation comes from the deflection of positrons and electrons in the geomagnetic field and is beamed in a cone around the direction of motion of the air shower. This radiation is reflected from the ice and subsequently detected by the ANITA experiment at a flight altitude of -36 km. In this contribution, we estimate the cosmic-ray energy of the 14 individual events and find a mean energy of 2:9-1018 eV. By simulating the ANITA flight, we calculate its exposure for ultra-high energy cosmic rays (UHECRs) and we estimate for the first time the cosmic-ray flux derived only from radio observations.

Abstract:

In August 2015 the direct dark matter search CRESST-II finished its second extensive data taking campaign (phase 2), after more than two years of measurement time. We present a preliminary analysis of a small data set of a single detector module called Lise. This detector features a threshold of 0.3 keV which is the lowest value for all detectors operated in phase 2. We show that the performance of this detector allows to efficiently make use of the low detection threshold providing high potential for a substantial gain in sensitivity in the regime of low dark matter particle masses.
