The gaseous features of the Magellanic System

In this talk, I will present the results of a study of high velocity clouds in the Magellanic Stream and the Leading Arm. The study uses the Galactic All-Sky Survey (GASS) and a newly conducted survey data of the Australia Telescope Compact Array (ATCA). The properties of HVCs in the two regions are compared and contrasted in order to study the different mechanisms shaping their structure and evolution. I will also present new discoveries from the study and report ongoing/future surveys on the Magellanic Clouds with state-of-the-art telescopes.
