On the time delay evolution of five Active Galactic Nuclei
Andjelka Kovacevic, Luka C. Popovic, Alla I. Shapovalova +3
Here we investigate light curves of the continuum and emission lines of five type 1 active galactic nuclei (AGN) from our monitoring campaign, to test time-evolution of their time…
Line shape variability in a sample of AGN with broad lines
D. Ilic, L. C. Popovic, A. I. Shapovalova +3
The spectral variability of active galactic nuclei (AGN) is one of their key features that enables us to study in more details the structure of AGN emitting regions. Especially, th…
Spectropolarimetric monitoring of active galaxy 3C390.3 with 6m telescope SAO RAS in the period 2009-2014
V. L. Afanasiev, A. I. Shapovalova, L. C. Popovic +1
Here we present the spectropolarimetric observations of the radio loud active galaxy 3C 390.3 in the period 2009-2014 (24 epochs). The galaxy has been observed with the 6-meter tel…
