Parkes observations for project P1349 semester 2025APRS_06

We propose an investigation of pulsars with interpulse (IP) emissions using the Ultra-wide-bandwidth Low (UWL) receiver at the Parkes (Murriyang) telescope. We aim to explore the polarization and emission properties of these pulsars through the application of the rotating vector model (RVM). Polarization profiles will be obtained across a wide bandwidth spanning 704 MHz to 4032 MHz. Emission heights will be measured using both the delay-radius and geometrical\n methods to examine their frequency dependence and test the radius-to-frequency mapping (RFM) model. Spectral analyses of different profile components will be conducted to constrain pulsar emission properties, while pulse intensity modulations will be analyzed to identify potential phase-lock phenomena. Our study will provide more information on the understanding of the properties of pulsars with IP emissions.
