Scientific paper

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 U.S. 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.
