Pulsars and their Environment
The radio emission from pulsars is routinely employed as a valuable probe of the structure and bulk motion of the warm ionized component of the ISM. The dispersion and interstellar scintillation of the radio signals can be used to obtain interesting information regarding the pulsars themselves. Moreover, the interaction of the relativistic outflows from pulsars with the surrounding ISM or a close stellar companion can offer valuable insight into the poorly understood properties of relativistic winds and colissionless shock as well as the small scale structure of the ISM.
