The structure of the Mg II broad line emitting region in Type 1 AGNs
Luka C. Popović, Jelena Kovacević-Dojcinović, Sladjana Marceta-Mandić
We investigate the structure of the Mg II broad line emission region in a sample of 284 Type 1 active galactic nuclei (AGNs), through comparing the kinematical parameters of the br…
Long-term optical spectral monitoring of NGC 7469
Alla I. Shapovalova, L. C. Popović, V. H. Chavushyan +11
We present the results of the long-term (20-year period, from 1996 to 2015) optical spectral monitoring of the Seyfert 1 galaxy NGC 7469. The variation in the light-curves of the b…
First long-term optical spectro-photometric monitoring of a binary black hole candidate E1821+643: I. Variability of spectral lines and continuum
A. I. Shapovalova, L. C. Popovic, V. H. Chavushyan +9
We report the results of the first long-term (1990-2014) optical spectro-photometric monitoring of a binary black hole candidate QSO E1821+643, a low-redshift high-luminosity radio…
Spectral optical monitoring of 3C390.3 in 1995-2007: I. Light curves and flux variation of the continuum and broad lines
A. I. Shapovalova, L. C. Popovic, A. N. Burenkov +9
Here we present the results of the long-term (1995-2007) spectral monitoring of the broad line radio galaxy \object{3C~390.3}, a well known AGN with the double peaked broad emissio…
