Abstract

The discovery that interstellar scintillation (ISS) is suppressed for compact radiosources at z 2 has enabled ISS surveys to be used as cosmological probes. We discuss brieflythe potential and challenges involved in such an undertaking, based on a dual-frequency surveyof ISS carried out to determine the origin of this redshift dependence.
