We present the results of the long-term optical monitoring campaign of active galactic nuclei (AGN) coordinated by the Special Astrophysical Observatory of the Russian Academy of Science. This campaign has produced a remarkable set of optical spectra

Using a long term spectroscopic observation of NGC 4151 (obtained with 6 m telescope of SAO Russia, between 1996 and 2006) we used Z‐Transfomed Discrete Correlation Function (ZDCF) to find the time lag between the broad Hβ and Hα lines and the op

We present results of a search for the most massive LBV-like stars in M 33 and discuss the list of OB+Hα stars. Spectral studies of the 70 brightest stars (V < 17.7) from the list have isolated 14 new LBV candidates. They are evolved the most massiv
