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…

Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395

Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31

We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…

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…
