ABSTRACT: There are many quasar samples with abnormal morphologies in the database of the MOJAVE website. The evolutionary forms of these samples are vastly different from the explanatory schemes (or models) described in existing theoretical frameworks. Among them, the relevant research articles on some samples (such as 0509+406) are few and far between, which indicates that under the current theoretical conditions, researchers are reluctant to be involved in these abnormal samples. However, the overall correlation of the quasar anomalies has been ignored. This might be an important reason why quasars, despite over 60 years of efforts since their discovery and research, have yet to make substantial progress. For the quasar samples 0509+406 and 2351+456 (4C45.51, z = 1.986), diffuse distribution knots occurred in the transverse direction of the jet axis. It seems difficult to explain this scene using the current popular research framework (SMBH+RBM, Supermassive Black Holes and Relativistic Beaming Model). The superluminal motion that occurred in 4C39.25 (z = 0.697) was not caused by the core component but by the jet knot (that is, the so-called “jets within jet” phenomenon), and remains unresolved at present. This paper attempts to illustrate that there is a correlation between the diffuse distribution knots in the transverse direction of the jet axis and the phenomenon of “jets within jet”. As for Quasar 4C39.25, its reasonable real picture may have been completely divorced from the existing theoretical framework.
