The post-maximum behaviour of the changing-look Seyfert galaxy NGC 1566
V. L. Oknyansky, H. Winkler, S. S. Tsygankov +6
We present results of the long-term multi-wavelength study of optical, UV and X-ray variability of the nearby changing-look (CL) Seyfert NGC 1566 observed with the Swift Observator…
New changing look case in NGC 1566
V. L. Oknyansky, H. Winkler, S. S. Tsygankov +5
We present a study of optical, UV and X-ray light curves of the nearby changing look active galactic nucleus in the galaxy NGC 1566 obtained with the Neil Gehrels Swift Observatory…
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…
