Radio and optical intra-day variability observations of five blazars

X. Liu, P. P. Yang, J. Liu +23

We carried out a pilot campaign of radio and optical band intra-day variability (IDV) observations of five blazars (3C66A, S5 0716+714, OJ287, B0925+504, and BL Lacertae) on Decemb…

Multi-Epoch Multiwavelength Spectra and Models for Blazar 3C~279

R. C. Hartman, M. Boettcher

Of the blazars detected by EGRET in GeV gamma rays, 3C 279 is not only the best-observed by EGRET, but also one of the best-monitored at lower frequencies. We have assembled eleven…
