Liverpool-Maidanak monitoring of the Einstein Cross in 20062019. I. Light curves in the optical bands and microlensing signatures
L. J. Goicoechea, B. P. Artamonov, V. N. Shalyapin +8
Quasar microlensing offers a unique opportunity to resolve tiny sources in distant active galactic nuclei and study compact object populations in lensing galaxies. We therefore sea…
Study of the Nuclear Activity of the Seyfert Galaxy NGC 7469 over the Period of Observations 2008-2014
L. Ugol'kova, B. Artamonov, E. Shimanovskaya +4
We present results of multicolor UBVRI observations of the type 1 Seyfert galaxy (SyG 1) NGC 7469 carried out at the 1.5-meter telescope of the Maidanak Observatory (Uzbekistan) in…
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…
Evolution of the cycles of magnetic activity of the Sun and Sun-like stars in time
E. A. Bruevich, V. V. Bruevich, B. P. Artamonov
We applied the method of continuous wavelet-transform to the time-frequency analysis to the sets of observations of relative sunspot numbers, sunspot areas and to 6 Mount Wilson HK…
New Estimates of Time Delays in the Gravitationally Lensed System PG1115+080
E. Shimanovskaya, V. Oknyansky, B. Artamonov
We analyze all publicly available long-term optical observations of the gravitationally lensed quasar PG1115+080 for the purpose of estimating time delays between its four componen…
Reverberation measurement of the inner radius of the dust torus in NGC 4151 during 2008-2013
V. L. Oknyansky, N. V. Metlova, O. G. Taranova +4
We investigate the correlation between infrared (JHKL) and optical (B) fluxes of the variable nucleus of the Seyfert galaxy NGC 4151 using partially published data for the last 6 y…
