Long-term multiwavelength monitoring and reverberation mapping of NGC 2617 during a changing-look event
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +32
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC~2617 carried out from 2016 until 2022 and covering the wavelength range fr…
Changing looks of the nucleus of the Seyfert galaxy NGC 1566 compared with other changing-look AGNs
Victor L. Oknyansky
We present results of a long-term optical, UV and X-ray study of variability of the nearby changing-look (CL) Seyfert NGC 1566 which was observed with the Swift Observatory from 20…
The curtain remains open: NGC 2617 continues in a high state
V. L. Oknyansky, C. M. Gaskell, N. A. Huseynov +17
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…
