ALMA observation of evolving magnetized corona in the radio-quiet changing-state AGN NGC 1566
Arghajit Jana, Claudio Ricci, Sophie M. Venselaar +9
The origin of compact millimeter (mm) continuum emission from radio-quiet AGNs (RQAGNs) is still not fully understood. Changing-state AGNs (CSAGNs) display rapid and strong variabi…
Investigating Changing-Look Active Galactic Nuclei with Long-term Optical and X-Ray Observations
A. Jana, C. Ricci, M. J. Temple +7
Changing-look active galactic nuclei (CLAGNs) show the appearance and disappearance of broad emission lines in their UV/optical spectra on timescales of months to decades. Here, we…
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…
Polarization in broad emission lines of Active Galactic Nuclei
L. C. Popović, E. Shablovinskaya, Dj. Savić
We discuss the polarization of broad emission lines in the type 1 active galactic nuclei (AGNs). The polarization depends on the geometry of the broad line region (BLR), and also o…
The first supermassive black hole mass measurement in active galactic nuclei using the polarization of broad emission line Mg II
Đorđe Savić, Luka Č. Popović, Elena Shablovinskaya
Spectropolarimetric efforts in the last few years have provided an efficient method that is based on the profiles of the polarization plane position angle of broad emission lines i…
Linear Spectropolarimetric Analysis of Fairall 9 with VLT/FORS2
Bo-Wei Jiang, Paola Marziani, Đorđe Savić +10
The quasar Main Sequence (MS) appears to be an incredibly powerful tool to organize the diversity in large samples of type-1 quasars but the most important physical parameters gove…
