Multiband optical variability of the blazar OJ 287 during its outbursts in 2015 -- 2016
Alok C. Gupta, A. Agarwal, A. Mishra +31
We present recent optical photometric observations of the blazar OJ 287 taken during September 2015 -- May 2016. Our intense observations of the blazar started in November 2015 and…
Optical Flickering of the recurrent nova RS Ophiuchi: amplitude - flux relation
R. Zamanov, G. Latev, S. Boeva +7
We report observations of the flickering variability of the symbiotic recurrent nova RS~Oph at quiescence in five bands (). We find evidence of a correlation between the pea…
Orbital parameters of the high-mass X-ray binary 4U 2206+54
K. A. Stoyanov, R. K. Zamanov, G. Y. Latev +2
We present new radial velocities of the high-mass X-ray binary star 4U 2206+54 based on optical spectra obtained with the Coude spectrograph at the 2m RCC telescope at the Rozhen N…
Photometric reverberation mapping of Markarian 279
R. Bachev, A. Strigachev, E. Semkov +9
By using standard broad-band VRI photometry we were able to discriminate the variations of the broad hydrogen alpha line from the continuum variations for the active galaxy Mkn 279…
