Interstellar Scintillation Studies of Pulsars and Distribution of Scattering Plasma in the Local Interstellar Medium

Pulsar scintillation measurements from the Ooty Radio Telescope (ORT) are used toinvestigate the distribution of scattering in the Local Interstellar Medium (LISM; region of ≲ 1 kpcof the Sun), specifically the region in and around the Local Bubble. A 3-component model, wherethe Solar neighborhood is surrounded by a shell of enhanced plasma turbulence, is proposed forthe LISM. Further, the Ooty data, along with those from Parkes and other telescopes are used forinvestigating the distribution of scattering towards the nearby Loop I Superbubble.
