Fourier domain excision of periodic radio frequency interference
Yogesh Maan, Joeri van Leeuwen, Dany Vohl
The discovery and study of pulsars and Fast Radio Bursts (FRBs) in time-domain radio data is often hampered by radio frequency interference (RFI). Some of this terrestrial RFI is i…
Multi-dimensional population modelling using frbpoppy: magnetars can produce the observed Fast Radio Burst sky
D. W. Gardenier, J. van Leeuwen
Fast Radio Bursts (FRBs) are energetic, short, bright transients that occur frequently over the entire radio sky. The observational challenges following from their fleeting, genera…
Dispersion measure variability for 36 millisecond pulsars at 150MHz with LOFAR
J. Y. Donner, J. P. W. Verbiest, C. Tiburzi +19
Radio pulses from pulsars are affected by plasma dispersion, which results in a frequency-dependent propagation delay. Variations in the magnitude of this effect lead to an additio…
First Discovery of a Fast Radio Burst at 350 MHz by the GBNCC Survey
E. Parent, P. Chawla, V. M. Kaspi +26
We report the first discovery of a fast radio burst (FRB), FRB 20200125A, by the Green Bank Northern Celestial Cap (GBNCC) Pulsar Survey conducted with the Green Bank Telescope at…
Single pulse modeling and the bi-drifting subpulses of radio pulsar B1839-04
Andrzej Szary, Joeri van Leeuwen, Patrick Weltevrede +1
We study the bi-drifting pulsar B1839-04, where the observed subpulse drift direction in the two leading pulse components is opposite from that in the two trailing components. Such…
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…
