Public Seminar of RPg Student:- Radio Interferometry Imaging and Polarimetry of Pulsar Wind Nebulae
A pulsar wind nebula(PWN) is a synchrotron nebula of relativistic particles from a pulsar. PWNe are natural laboratories for studying magnetohydrodynamics(MHD) in relativistic environments. In the radio bands, synchrotron radiation is the main emission mechanism. Radio observations can therefore reveal the particles energy distribution and magnetic field structure. Previous studies suggest diverse magnetic field configurations for PWNe, but the exact reason remains unclear. In this study, the speaker uses radio interferometers(e.g., the VLA) to obtain high-resolution images of PWNe. The new results could help understand the particle acceleration process and MHD in these objects. Various models and simulations of PWNe will be discussed.
