On a precessing jet-nozzle scenario with a common helical trajectory-pattern for blazar 3C345

S. J. Qian

The kinematics and flux evolution of the superluminal knots in blazar 3C345 were interpreted in the framework of the precessing jet-nozzle scenario with a precessing common helical…

Flux evolution and kinematics of superluminal components in blazar 3C345

S. J. Qian

The precessing jet-nozzle scenario previously proposed was applied to model-fit the kinematics of five superluminal components (C19,C20,C21,B5 and B7) of jet-B in blazar 3C345. Bas…

Flux evolution of superluminal components in blazar 3C454.3

S. J. Qian

The kinematic behavior of superluminal components observed at 43 GHz in blazar 3C454.3 were model-fitted with their light curves interpreted in terms of their Doppler-boosting effe…

Kinematics and flux evolution of superluminal components in QSO B1308+326

S. J. Qian

Search for Doppler-boosting effect in flux evolution of superluminal components in blazars has been an important subject, which can help clarify their kinematic and emission proper…

Doppler boosting effect and flux evolution of superluminal components in QSO 3C345

S. J. Qian

The precessing jet-nozzle scenario previously proposed was applied to interpret the VLBI-measured kinematics of five superluminal components (C4,C5,C9,C10 and C22) and their flux d…

Possible evidence for double precessing nozzle structure in QSO 3C345

S. J. Qian

The precessing jet-nozzle scenario has been applied to interpret the VLBI-kinematics of twenty-seven superluminal components in blazar 3C345 measured during an about 38-yr period.…

Polarization behavior of periodic optical outbursts in blazar OJ287

S. J. Qian

As a characteristic feature of generic blazars the polarization behavior of the quasi-periodic optical outbursts observed in OJ287 is investigated. The optical light-curves of the…
