Opportunities to Search for Extra-Terrestrial Intelligence with the Five-hundred-meter Aperture Spherical radio Telescope
Di Li, Vishal Gajjar, Pei Wang +31
The discovery of ubiquitous habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, has ushered in a renaissance in th…
Choosing a Maximum Drift Rate in a SETI Search: Astrophysical Considerations
Sofia Z. Sheikh, Jason T. Wright, Andrew P. Siemion +1
A radio transmitter which is accelerating with a non-zero radial component with respect to a receiver will produce a signal that appears to change its frequency over time. This eff…
The Breakthrough Listen Search for Extraterrestrial Intelligence
Vishal Gajjar, Andrew Siemion, Steve Croft +34
The discovery of the ubiquity of habitable extrasolar planets, combined with revolutionary advances in instrumentation and observational capabilities, have ushered in a renaissance…
Thunderstorm electric fields probed by extensive air showers through their polarized radio emission
T. N. G. Trinh, O. Scholten, A. Bonardi +17
We observe a large fraction of circular polarization in radio emission from extensive air showers recorded during thunderstorms, much higher than in the emission from air showers m…
Search for Cosmic Particles with the Moon and LOFAR
T. Winchen, A. Bonardi, S. Buitink +14
The low flux of the ultra-high energy cosmic rays (UHECR) at the highest energies provides a challenge to answer the long standing question about their origin and nature. A signifi…
Timing calibration and spectral cleaning of LOFAR time series data
A. Corstanje, S. Buitink, J. E. Enriquez +10
We describe a method for spectral cleaning and timing calibration of short voltage time series data from individual radio interferometer receivers. It makes use of the phase differ…
Calibrating the absolute amplitude scale for air showers measured at LOFAR
A. Nelles, J. R. Hörandel, T. Karskens +74
Air showers induced by cosmic rays create nanosecond pulses detectable at radio frequencies. These pulses have been measured successfully in the past few years at the LOw Frequency…
Measurement of the cosmic-ray energy spectrum above eV with the LOFAR Radboud Air Shower Array
S. Thoudam, S. Buitink, A. Corstanje +11
The energy reconstruction of extensive air showers measured with the LOFAR Radboud Air Shower Array (LORA) is presented in detail. LORA is a particle detector array located in the…
Measuring a Cherenkov ring in the radio emission from air showers at 110-190 MHz with LOFAR
A. Nelles, P. Schellart, S. Buitink +66
Measuring radio emission from air showers offers a novel way to determine properties of the primary cosmic rays such as their mass and energy. Theory predicts that relativistic tim…
A method for high precision reconstruction of air shower Xmax using two-dimensional radio intensity profiles
S. Buitink, A. Corstanje, J. E. Enriquez +10
The mass composition of cosmic rays contains important clues about their origin. Accurate measurements are needed to resolve long-standing issues such as the transition from Galact…
Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
