Description

The Thousand Pulsar Array (TPA) program provides a large pulsar dataset that has been collected over five years with MeerKAT, the most sensitive radio telescope in the Southern Hemisphere. Beyond its primary goals of studying pulsar emission and population statistics, the TPA program also enables the analysis of the interstellar medium (ISM) - a crucial step toward understanding the electron density distribution and turbulent structures of the Milky Way. In this poster, I will describe the first large-scale study of pulsar scattering performed with the MeerKAT data. We expand on previous studies on smaller samples and report the time variability of scattering, improving our current understanding of ISM structures and turbulence. While this study focuses on a sample of young pulsars, the techniques developed are applicable to scattering studies of FRBs and millisecond pulsars.
