Changing looks of the nucleus of Seyfert galaxy NGC 3516 during 2016-2020
V. L. Oknyansky, Kh. M. Mikailov, N. A. Huseynov
The results of spectral observations of NGC 3516 with the 2-m telescope of the Shamakhy Astrophysical Observatory during 2016-2020 are presented. In the first half of 2016, the int…
Supernova 2018aoq and a distance to Seyfert galaxy NGC 4151
D. Yu. Tsvetkov, P. V. Baklanov, M. Sh. Potashov +9
We present optical photometric observations of SN 2018aoq from 2 to 100 days after explosion, and 7 spectra at epochs from 11 to 71 days. The light curves and spectra are typical f…
Multi-wavelenth monitoring of the changing-look AGN NGC 2617 during state changes
V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +18
Optical and near-infrared photometry, optical spectroscopy, and soft X-ray and UV monitoring of the changing-look active galactic nucleus NGC 2617 show that it continues to have th…
