More SUPERB pulsars
The SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB) ran from 2014 April to 2019 August, covering a large fraction of the southern hemisphere at mid- to high-galactic latitudes. The survey was conducted by making 9-minute pointings with the 20-cm multibeam receiver on the Parkes Radio Telescope. The most recent data release, containing data up to 2017 September have been searched using standard Fourier techniques, single-pulse searches, and Fast Folding Algorithm searches. Spiewak et al. present 19 new discoveries, bringing the total to 27 discoveries in the programme, and they report the results of follow-up timing observations at Parkes for 26 of these pulsars, The figure above shows polarization-calibrated profiles of three new pulsars, illustrating the variety seen in pulsar profiles. The bottom panel of each subfigure shows the pulse profiles, with total intensity in black, linear polarization in red, and circular polarization in blue. The top panels show the polarization angle as a function of pulse phase. The interpulse for PSR J1544−0713, which appears half a rotation from the main pulse, is shown in the inset plot of the last panel. More details are given in the paper , to be published in Monthly Notices of the Royal Astronomical Society.
