Handbook of Neuropsychology and AgingWe have measured radio polarization of about 90 blazars at 3cm with the 45-m radio telescope of Nobeyama Radio Observatory. Polarization degree and angle of the blazars exhibit significant correlations with their VLBI structure, and core dominance.The correlations are explained by mixture with the extended polarized flux or aberration effect.

https://doi.org/10.1007/978-1-59259-165-7Results of photographic observations of three BL Lac objects: ON 231, ON 325 and RS 4 are presented. Our measurements and previous data were combined to construct light curves extending over the last 20 years. No clear periodic behaviour was found. Some possible correlations of optical data with information available in other bands are discussed.

Statistical properties of radio polarization of blazars,We have measured radio polarization of about 90 blazars at 3cm with the 45-m radio telescope of Nobeyama Radio Observatory. Polarization degree and angle of the blazars exhibit significant correlations with their VLBI structure, and core dominance.The correlations are explained by mixture with the extended polarized flux or aberration effect.

Radio variability of BL Lacs and related objects: Observations vs. shocked jet models,The properties of compact extragalactic radio sources are investigated using a sample of 27 sources extensively observed at millimeter frequencies. It is suggested that the radio variability of all AGN, independent of their classification, can be understood in terms of growing and decaying shocks in a jet.

Simultaneous UBVRI polarimetry of blazars,We present simultaneous UBVRI photopolarimetry of 12 blazars and one low polarization quasar, 3C 273. The aim of our observations has been to study frequency-dependent polarization in these sources.
