The compact radio structure of the high redshift quasars 0642+449, 1402+044, 1614+051
Abstract
In the first stage of an investigation of possible cosmological evolution effects in the compact radio structure of quasars, we have used a combined European and US VLBI network to image the milliarcsec scale morphology of three quasars with redshifts greater than 3. The sources 0642+449 (z = 3.406) and 1402+044 (z = 3.208) display weak distorted jets, while 1614+051 (z = 3.212) is slightly resolved. The jets in 0642+449 and 1402+044 are the most distant known in the universe.
