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…
Narrow lines correlations in an SDSS sample of type 1 quasars
I. Jankov, D. Ilić
Investigation of quasar emission line properties and relationships between spectral parameters is important for understanding the physical mechanisms that originate inside differen…
The intrinsic Baldwin effect in NLSy 1 galaxies
Nemanja Rakić, Dragana Ilić, Luka Č. Popović
The intrinsic Baldwin effect is an anti-correlation between the line equivalent width and the flux of the underlying continuum detected in a single variable active galactic nucleus…
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 the double peaked emission line AGN Arp 102B: II. Variability of the broad line properties
L. C. Popovic, A. I. Shapovalova, D. Ilic +9
We investigate a long-term (26 years, from 1987 to 2013) variability in the broad spectral line properties of the radio galaxy Arp 102B, an active galaxy with broad double-peaked e…
