“…The key issue is whether the radio plasma and ionizing photons are collimated on the same or different spatial scales. The most stringent limit on the collimation of radio ejecta in Seyferts is provided by VLBI observations of NGC 4151 (Harrison et al 1986), which show that the collimation occurs on a scale < 2 pc. HST observations of NGC 1068 (Evans et al 1991), NGC 4151 (Evans et al 1993), and NGC 5728 (Wilson et al 1993) indicate that the ionization cones are formed < 20 pc from the nucleus.…”

“…Extended X-ray emission at the brightest parts of the ENLR was discovered by Elvis et al (1983). The radio structure is a collection of resolved sources (Harrison et al 1986). The nuclear jets are at arcsec scale at PA ∼ 70 − 80…”
