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…
Spectroscopy and multiband photometry of the afterglow of intermediate duration gamma-ray burst 040924 and its host galaxy
K. Wiersema, A. J. van der Horst, D. A. Kann +19
We present optical photometry and spectroscopy of the afterglow and host galaxy of gamma-ray burst 040924. This GRB had a rather short duration of T90 ~2.4s, and a well sampled opt…
Optical and radio variability of the BL Lac object AO 0235+16: a possible 5-6 year periodicity
C. M. Raiteri, M. Villata, H. D. Aller +33
New optical and radio data on the BL Lacertae object AO 0235+16 have been collected in the last four years by a wide international collaboration, which confirm the intense activity…
Multiwavelength Observations of a Dramatic High Energy Flare in the Blazar 3C 279
A. E. Wehrle, E. Pian, C. M. Urry +3
The blazar 3C 279, one of the brightest identified extragalactic objects in the gamma-ray sky, underwent a flare of a factor 10 amplitude in gamma-rays towards the end of a 3-week…
