Photometry requested of Blazar-type Quasars 3C 273 and 3C 279
Abstract:
Dr. Kirill Sokolovsky has requested the assistance of AAVSO observers to obtain optical photometry of the blazar-type quasars 3C 273 and 3C 279 during 2011. The observations obtained by AAVSO observers will be combined with multiwavelength observations - from radio to gamma-rays - as well as with very long baseline interferometry with the VLBA to obtain a better picture of what these objects are and how they vary. Sokolovsky and collaborators hope to find correlations between the spectral energy distributions (SEDs) of these objects and the behavior of the associated relativistic jets at sub-parsec spatial resolution.
