Abstract
Evidence is presented that radio sources are more bent at larger redshifts. This effect is interpreted as due to interaction of the radio source with an ambient circumgalactic medium which must then have been clumpier at early epochs. It is suggested that the increased dumpiness could be associated with the late stages of galaxy formation and possibly also with CIV absorption line systems.
