Pulsar science with data from the Large European Array for Pulsars

The Large European Array for Pulsars( LEAP) is a European Pulsar Timing Arrayproject that combines the Lovell, Effelsberg, Nan\c{c}ay, Sardinia, and Westerbork radio telescopesinto a single tied-array, and makes monthly observations of a set of millisecond pulsars(MSPs). The overview of our experiment is presented in Bassa et al. (2016). Baseband data are recorded at a central frequency of 1396 MHz and a bandwidth of 128 MHz at each telescope, and are correlated offline on a cluster at Jodrell Bank Observatoryusing a purpose-built correlator, detailed in Smits et al. (2017). LEAPoffers a substantial increase in sensitivity over that of the individual telescopes, and can operate in timing and imaging modes (notably in observations of the galactic centre radio magnetar; Wucknitz 2015). To date, 4 years of observations have been reduced. Here, we report on the scientific projects which have made use of LEAPdata.
