摘要:

脉冲星和河外射电暴的调查从2014年4月持续到2019年8月,覆盖了南半球中高银河系纬度的大部分地区,由帕克斯射电望远镜上的20厘米多波束接收器拍摄的9分钟点组成。截至2017年9月21日的数据已经使用标准傅立叶技术,单脉冲搜索和快速折叠算法搜索进行了搜索。我们提出了19个新发现,使该计划中的发现总数达到27个,我们报告了在帕克斯对其中26个脉冲星进行后续定时观测的结果,包括毫秒脉冲星PSR J1421-4409;微弱,高度调制的慢脉冲星PSR J1646-1910;和零脉冲星PSR J1337-4441。我们提出了新的定时解决方案,23颗星,我们报告的通量密度,调制指数,和偏振特性。

英文摘要:

The SUrvey for Pulsars and Extragalactic Radio Bursts ran from 2014 April to 2019 August, covering a large fraction of the southern hemisphere at mid- to high-galactic latitudes, and consisting of 9-minute pointings taken with the 20-cm multibeam receiver on the Parkes Radio Telescope. Data up to 2017 September 21 have been searched using standard Fourier techniques, single-pulse searches, and Fast Folding Algorithm searches. We present 19 new discoveries, bringing the total to 27 discoveries in the programme, and we report the results of follow-up timing observations at Parkes for 26 of these pulsars, including the millisecond pulsar PSR J1421-4409; the faint, highly-modulated, slow pulsar PSR J1646-1910; and the nulling pulsar PSR J1337-4441. We present new timing solutions for 23 pulsars, and we report flux densities, modulation indices, and polarization properties.
