Spectropolarimetry of the changing-look active galactic nucleus NGC 1566 and its potential link to supermassive black hole binaries
F. Marin, V. H. Sasse, J. Biedermann +4
The AGN NGC~1566 is known to present dramatic and regular spectral shape changes, associated with the appearance and disappearance of broad emission lines. The underlying mechanism…
Polarization properties of changing-look active galactic nuclei: NGC 1365 and NGC 2992
D. Hutsemékers, F. Marin, B. Agis González +2
Changing-look active galactic nuclei (CLAGNs) represent a rare class of AGNs that undergo transitions from type 1 (characterized by the presence of broad emission lines in their sp…
XPE and VLT /FORS2 polarimetry challenge the Seyfert-1.9 classification of MCG-05-23-16
Frédéric Marin, Daniele Tagliacozzo, Francesco Ursini +21
We report the third observation of the Seyfert-1.9 active galactic nucleus (AGN) MCG-05-23-16 with the Imaging X-ray Polarimetry Explorer (\textit{IXPE}), together with optical spe…
