A GPU-based survey for millisecond radio transients using ARTEMIS
W. Armour, A. Karastergiou, M. Giles +7
Astrophysical radio transients are excellent probes of extreme physical processes originating from compact sources within our Galaxy and beyond. Radio frequency signals emitted fro…
Real-time, fast radio transient searches with GPU de-dispersion
Alessio Magro, Aris Karastergiou, Stefano Salvini +3
The identification, and subsequent discovery, of fast radio transients through blind-search surveys requires a large amount of processing power, in worst cases scaling as $\mathcal…
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…
A transient component in the pulse profile of PSR J0738-4042
Aris Karastergiou, Steve J. Roberts, Simon Johnston +3
One of the tenets of the radio pulsar observational picture is that the integrated pulse profiles are constant with time. This assumption underpins much of the fantastic science ma…
