Parkes observations for project P1069 semester 2020APRS_02
We propose to carry out Parkes follow-up observations of pulsar candidates identified in the Rapid ASKAP Continuum Survey (RACS). This is the first all-sky pulsar survey in the imaging domain in the southern hemisphere thanks to ASKAP. Eight sources have been selected because of (1) their very high fraction of circular polarisation; (2) their lack ... moreof optical counterparts; (3) strong variability, which might indicate either strong interstellar scintillation or eclipsing by companion stars if in binaries; (4) the non-detection of these relatively bright sources in previous pulsar surveys, which might indicate extreme nature of these candidates. High time and frequency resolution targeted search with UWL are proposed. Such observations will enable us to carry out deep searches of pulsars with very short spin periods or in compact binaries. less

P1069 - Follow-up of pulsar candidates in the Rapid ASKAP Continuum Survey
Neutron stars contain more mass than the Sun collapsed into the size of a city. Many of these neutron stars rotate hundreds of times per second and emit beams of radio waves that we can detect on Earth, in lighthouse-like fashion. Traditionally, these extreme objects are found by searching for periodic signals recorded by single dish telescopes, su... morech as Parkes. However, recently we showed that neutron stars can also be identified in radio images with observations taken by the Australian SKA Pathfinder, ASKAP. Here we propose to observe eight pulsar candidates identified in the new ASKAP all-sky survey, which might lead to discoveries of exciting pulsars. less
