Reconstruction of anomalous air showers with SKA-Low
Vital De Henau, Sjoerd Bouma, Justin Bray +31
Double-bump showers are a surprising class of extensive air showers (EAS) predicted by Monte Carlo simulations, which, so far, no experiment has been able to directly detect. They…
Sporadic radio pulses from a white dwarf binary at the orbital period

We present an updated cosmic-ray mass composition analysis in the energy range to eV from 334 air showers measured with the LOFAR radio telescope, and selec…
LOFAR early-time search for coherent radio emission from Short GRB 181123B
A. Rowlinson, R. L. C. Starling, K. Gourdji +6
The mergers of two neutron stars are typically accompanied by broad-band electromagnetic emission from either a relativistic jet or a kilonova. It has also been long predicted that…
