There is overwhelming observational evidence showing the ubiquity of turbulence in the interstellar medium (ISM), which is sampled by many lines of sight toward Galactic pulsars. Pulsar signals that traverse through the turbulent density field undergo multi-path scattering, with the radio pulses broadened in time. The scatter-broadening observations of a sizable sample of pulsars make a useful...   More >
