The nature of the intra-night optical variability in blazars
R. Bachev, E. Semkov, A. Strigachev +5
In this paper we present results of a short-term optical monitoring of 13 blazars. The objects were monitored mostly in the R-band for a total of ~ 160 hours between 2006 and 2011.…
Optical Flux and Spectral Variability of Blazars
Haritma Gaur, Alok C. Gupta, A. Strigachev +9
We report the results of optical monitoring for a sample of 11 blazars including 10 BL Lacs and 1 Flat Spectrum Radio Quasar (FSRQ). We have measured the multiband optical flux and…
Multiwavelength Intraday Variability of the BL Lac S5 0716+714
Alok C. Gupta, T. P. Krichbaum, P. J. Wiita +31
We report results from a 1 week multi-wavelength campaign to monitor the BL Lac object S5 0716+714 (on December 9-16, 2009). In the radio bands the source shows rapid (~ (0.5-1.5)…
