MOJAVE XIX: Brightness Temperatures and Intrinsic Properties of Blazar Jets

Autor: Homan, D. C., Cohen, M. H., Hovatta, T., Kellermann, K. I., Kovalev, Y. Y., Lister, M. L., Popkov, A. V., Pushkarev, A. B., Ros, E., Savolainen, T.

We present multi-epoch, parsec-scale core brightness temperature observations of 447 AGN jets from the MOJAVE and 2cm Survey programs at 15 GHz from 1994 to 2019. The brightness temperature of each jet over time is characterized by its median value a

We have obtained a smooth time series for the Electric Vector Position Angle (EVPA) of the blazar OJ 287 at centimeter wavelengths, by making $\pm n\pi$ adjustments to archival values from 1974 to 2016. The data display rotation reversals in which th
