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…
