On the Dispersion Measure of High-Redshift Synchrotron Sources    [PDF]

R. V. E. Lovelace, D. W. Richards

A method is proposed for deriving the dispersion measure (related to the line-of-sight integrated free electron density) to high-redshift, powerful synchrotron radio sources by analysis of the temporal/spectral properties of the recorded signals. This would allow direct measurements of the distributed density of ionized baryons along the line-of-sights to the sources.
