Parkes observations for project P1411 semester 2026APRS_02

Conventional blind pulsar surveys that search for periodic signals in high-time-resolution data are increasingly limited by interstellar scattering at high dispersion measure (DM), orbital modulation in compact binaries, scintillation effects, and intensive computational demands. The Australian Square Kilometre Array Pathfinder (ASKAP) Evolutionary Map of the Universe (EMU) survey provides ultra-deep radio continuum maps enabling complementary image-domain pulsar searches that bypass these limitations. We have discovered seven new pulsars through three targeted strategies: (1) identifying compact sources embedded in supernova remnants (SNRs) and pulsar wind nebulae (PWNe), (2) detecting highly variable sources via variance imaging, and (3) selecting highly circularly polarised compact sources. Our sample includes three highly scattered pulsars (PSR J1638-4713 , PSR J1643-4511, and PSR J1631-4722 with DM > 800 pc/cm^3) including two pulsars associated with PWNe. Two millisecond pulsars (PSR J0927-7641 and PSR J1838-5949) are in potential wide binary systems with orbital periods of several tens of days, and two additional normal pulsars (PSR J1153-7106 and PSR 2223-0654). We propose follow-up timing observations of these pulsars with Murriyang's Ultra-Wideband Low (UWL) receiver to obtain phase-connected timing solutions, measure precise positions and spin parameters, and determine orbital characteristics for the binary systems,. These observations will enable studies of pulsar formation mechanisms, binary evolution pathways, PWN-SNR interactions, and validate image-based discovery techniques as powerful complements to traditional blind surveys for detecting elusive pulsars.
