Influence of the optical Fe II quasi-continuum on measuring the spectral parameters of active galactic nuclei
Luka Č. Popović, Jelena Kovačević-Dojčinović, Ivan Dojčinović +1
We explore the influence of optical Fe II quasi-continuum on the measured spectral parameters in the 4150-5500 A range for the spectra of Type 1 active galactic nuclei (AGNs). We a…
Long-term optical spectral monitoring of a changing-look active galactic nucleus NGC 3516 -- II. Broad-line profile variability
Luka C. Popović, Dragana Ilić, Alexander Burenkov +10
We analyze the broad H line profile variability of the "changing look" active galactic nucleus (CL-AGN) NGC 3516 over a long period of 25 years. The observed change in the broad…
Narrow vs. Broad line Seyfert 1 galaxies: X-ray, optical and mid-infrared AGN characteristics
Maša Lakićević, Luka Č. Popović, Jelena Kovačević-Dojčinović
We investigated narrow line Seyfert 1 galaxies (NLS1s) at optical, mid-infrared (MIR) and X-ray wavelengths, comparing them to the broad line active galactic nuclei (BLAGNs). We fo…
The optical vs. mid-infrared spectral properties of 82 Type 1 AGNs: coevolution of AGN and starburst
Maša Lakićević, Jelena Kovačević-Dojčinović, Luka Č. Popović
We investigated the connection between the mid-infrared (MIR) and optical spectral characteristics in a sample of 82 Type 1 active galactic nuclei (AGNs), observed with Infrared Sp…
Virilization of the Broad Line Region in Active Galactic Nuclei - connection between shifts and widths of broad emission lines
Sanja Jonic, Jelena Kovacevic-Dojcinovic, Dragana Ilic +1
We investigate the virilization of the emission lines Hbeta and Mg II in the sample of 287 Type 1 Active Galactic Nuclei taken from the Sloan Digital Sky Survey database. We explor…
