A Possible Periodicity in the Radio Lightcurves of 3C454.3
S. J. Qian, N. A. Kudryavtseva, S. Britzen +6
During the period 1966.5 - 2006.2 the 15GHz and 8GHz lightcurves of 3C454.3 (z=0.859) show a qsasi-periodicity of ~12.8 yr (~6.9 yr in the rest frame of the source) with a double-b…
The Be/X-ray transient 4U 0115+63/V635 Cassiopeiae. III. Quasi-cyclic variability
P. Reig, V. Larionov, I. Negueruela +2
4u 0115+63 is one of the most active and best studied Be/X-ray transients. Previous studies of 4u0115+63 have led to the suggestion that it undergoes relatively fast quasi-cyclic a…
A search for periodicity in the light curves of selected blazars
N. A. Kudryavtseva, T. B. Pyatunina
We present an analysis of multifrequency light curves of the sources 2223-052 (3C 446), 2230+114 (CTA 102), and 2251+158 (3C 454.3), which had shown evidence of quasi-periodic acti…
The WEBT BL Lacertae Campaign 2001 and its extension
M. Villata, C. M. Raiteri
BL Lacertae has been the target of four observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration. In this paper we present light curves obtained by the…
