The impact of Solar wind variability on pulsar timing
C. Tiburzi, G. M. Shaifullah, C. G. Bassa +22
High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are varia…
LOFAR 144-MHz follow-up observations of GW170817
J. W. Broderick, T. W. Shimwell, K. Gourdji +66
We present low-radio-frequency follow-up observations of AT 2017gfo, the electromagnetic counterpart of GW170817, which was the first binary neutron star merger to be detected by A…
Cassiopeia A, Cygnus A, Taurus A, and Virgo A at ultra-low radio frequencies
F. de Gasperin, J. Vink, J. P. McKean +49
The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are ca…
The LOFAR Tied-Array All-Sky Survey (LOTAAS): Survey overview and initial pulsar discoveries
S. Sanidas, S. Cooper, C. G. Bassa +20
We present an overview of the LOFAR Tied-Array All-Sky Survey (LOTAAS) for radio pulsars and fast transients. The survey uses the high-band antennas of the LOFAR Superterp, the den…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
Probing Atmospheric Electric Fields in Thunderstorms through Radio Emission from Cosmic-Ray-Induced Air Showers
P. Schellart, T. N. G. Trinh, S. Buitink +71
We present measurements of radio emission from cosmic ray air showers that took place during thunderstorms. The intensity and polarization patterns of these air showers are radical…
