A flare in the optical spotted in the changing-look Seyfert NGC 3516
D. Ilic, V. Oknyansky, L. C. Popovic +14
We present observations from the short-term intensive optical campaign (from Sep2019 to Jan2020) of the changing-look Seyfert NGC 3516. This active galactic nucleus is known to hav…
The Relative Wavelength Independence of IR Time Lags in NGC4151 During the Years 2010-2015
V. L. Oknyansky, V. I. Shenavrin, N. V. Metlova +1
We present results of a study of the correlation between the infrared (JHKL) and optical(B) fluxes of the nucleus of the Seyfert galaxy NGC 4151 for the years 2010 - 2015 using our…
Study of the Nuclear Activity of the Seyfert Galaxy NGC 7469 over the Period of Observations 2008-2014
L. Ugol'kova, B. Artamonov, E. Shimanovskaya +4
We present results of multicolor UBVRI observations of the type 1 Seyfert galaxy (SyG 1) NGC 7469 carried out at the 1.5-meter telescope of the Maidanak Observatory (Uzbekistan) in…
Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205
A. O. Simon, A. V. Bondar, N. V. Metlova
We report about new episode of decretion disk formation in the IGR J06074+2205 system. Obtained spectral data gives us opportunity to measure peak separation in double-peaked Hα li…
