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…
RFI Flagging Implications for Short-Duration Transients
Y. Cendes, P. Prasad, A. Rowlinson +24
With their wide fields of view and often relatively long coverage of any position in the sky in imaging survey mode, modern radio telescopes provide a data stream that is naturally…
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…
The LOFAR Pilot Surveys for Pulsars and Fast Radio Transients
Thijs Coenen, Joeri van Leeuwen, Jason W. T. Hessels +87
We have conducted two pilot surveys for radio pulsars and fast transients with the Low-Frequency Array (LOFAR) around 140 MHz and here report on the first low-frequency fast-radio…
LOFAR: The LOw-Frequency ARray
M. P. van Haarlem, M. W. Wise, A. W. Gunst +197
LOFAR, the LOw-Frequency ARray, is a new-generation radio interferometer constructed in the north of the Netherlands and across europe. Utilizing a novel phased-array design, LOFAR…
Differential Frequency-dependent Delay from the Pulsar Magnetosphere
T. E. Hassall, B. W. Stappers, P. Weltevrede +60
Some radio pulsars show clear drifting subpulses, in which subpulses are seen to drift in pulse longitude in a systematic pattern. Here we examine how the drifting subpulses of PSR…
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…
Pilot pulsar surveys with LOFAR
Thijs Coenen, The LOFAR Pulsar Working Group
We are performing two complementary pilot pulsar surveys as part of LOFAR commissioning. The LOFAR Pilot Pulsar Survey (LPPS) is a shallow all-sky survey using an incoherent combin…
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…
A search for radio pulsations from neutron star companions of four subdwarf B stars
Thijs Coenen, Joeri van Leeuwen, Ingrid H. Stairs
We searched for radio pulsations from the potential neutron star binary companions to subdwarf B stars HE 0532-4503, HE 0929-0424, TON S 183 and PG 1232-136. Optical spectroscopy o…
Observing pulsars and fast transients with LOFAR
B. W. Stappers, J. W. T. Hessels, A. Alexov +91
Low frequency radio waves, while challenging to observe, are a rich source of information about pulsars. The LOw Frequency ARray (LOFAR) is a new radio interferometer operating in…
Early Pulsar Observations with LOFAR
Jason Hessels, Ben Stappers, Anastasia Alexov +10
This contribution to the proceedings of "A New Golden Age for Radio Astronomy" is simply intended to give some of the highlights from pulsar observations with LOFAR at the time of…
The LOFAR Transients Key Project
Rob Fender, Robert Braun, Ben Stappers +18
LOFAR, the Low Frequency Array, is a new radio telescope under construction in the Netherlands, designed to operate between 30 and 240 MHz. The Transients Key Project is one of the…
