A LOFAR radio search for single and periodic pulses from M31
Joeri van Leeuwen, Klim Mikhailov, Evan Keane +5
Bright, short radio bursts are emitted by sources at a large range of distances: from the nearby Crab pulsar to remote Fast Radio Bursts (FRBs). FRBs are likely to originate from d…
A search for pulsars in subdwarf B binary systems and discovery of giant-pulse emitting PSR J0533-4524
L. C. Oostrum, J. van Leeuwen, Y. Maan +2
Binary millisecond pulsars (MSPs) provide several opportunities for research of fundamental physics. However, finding them can be challenging. Several subdwarf B (sdB) binary syste…
LOFAR Observations of Swift J1644+57 and Implications for Short-Duration Transients
Y. Cendes, R. A. M. J. Wijers, J. D. Swinbank +25
Aims: We have analyzed low frequency radio data of tidal disruption event (TDE) Swift J1644+57 to search for a counterpart. We consider how brief transient signals (on the order of…
Synchronous X-ray and Radio Mode Switches: a Rapid Global Transformation of the Pulsar Magnetosphere
W. Hermsen, J. W. T. Hessels, L. Kuiper +8
Pulsars emit low-frequency radio waves through to high-energy gamma-rays that are generated anywhere from the surface out to the edges of the magnetosphere. Detecting correlated mo…
Wide-band Simultaneous Observations of Pulsars: Disentangling Dispersion Measure and Profile Variations
T. E. Hassall, B. W. Stappers, J. W. T. Hessels +91
Dispersion in the interstellar medium is a well known phenomenon that follows a simple relationship, which has been used to predict the time delay of dispersed radio pulses since t…
