Variability and stability in blazar jets on time scales of years: Optical polarization monitoring of OJ287 in 2005-2009
C. Villforth, K. Nilsson, J. Heidt +45
(Abridged) OJ287 is a BL Lac object that has shown double-peaked bursts at regular intervals of ~12 yr during the last ~40 yr. We analyse optical photopolarimetric monitoring data…

A massive binary black-hole system in OJ287 and a test of general relativity
M. J. Valtonen, H. J. Lehto, K. Nilsson +23
Tests of Einstein's general theory of relativity have mostly been carried out in weak gravitational fields where the space-time curvature effects are first-order deviations from Ne…
