Nuclear Millimeter Continuum Emission in Radio-Quiet Active Galactic Nuclei: an ALMA Spectral and Variability Study
Sophie M. Venselaar, Claudio Ricci, Yoshiyuki Inoue +8
Unresolved millimeter (mm) emission is observed in radio-quiet (RQ) Active Galactic Nuclei (AGN), but its physical origin remains debated. Self-absorbed synchrotron emission from t…
The Millimeter/X-ray Relation in Rapidly Accreting Supermassive Black Holes at
Sophie M. Venselaar, Claudio Ricci, Santiago Del Palacio +12
A tight correlation between nuclear millimeter and X-ray emission has recently been found in nearby () and low-Eddington ratio () radio-quiet Active Ga…
Multi-wavelength properties of changing-state active galactic nuclei: I. the evolution of soft excess and X-ray continuum
Arghajit Jana, Claudio Ricci, Alessia Tortosa +11
Changing-state active galactic nuclei (CSAGNs) exhibit rapid variability, with mass accretion rates that can change by several orders of magnitude in a few years. This provides us…
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…
Estimating supermassive black hole masses in AGNs using polarization of broad MgII, H and H lines
Đorđe Savić, Luka Č. Popović, Elena Shablovinskaya +1
For type-1 active galactic nuclei (AGNs) for which the equatorial scattering is the dominant broad line polarization mechanism, it is possible to measure the supermassive black hol…
Active Galactic Nuclei in polarized light
Elena Shablovinskaya, Viktor Afanasiev
Due to the compactness active galactic nuclei (AGNs) are still unresolved with optical observations. However, structure and physical conditions of the matter in their central parts…
Measuring the AGN sublimation radius with a new approach: reverberation mapping of the broad line polarization
E. S. Shablovinskaya, V. L. Afanasiev, L. Č. Popović
Here we give an observational method for measurements of the equatorial scattering region radius using variability in the polarized broad lines in Type 1 active galactic nuclei (AG…
