The Eddington ratio-dependent changing look events in NGC 2992
Muryel Guolo, Daniel Ruschel-Dutra, Dirk Grupe +5
We present an analysis of historical multi-wavelength emission of the Changing Look (CL) Active Galactic Nucleus (AGN) in NGC 2992, covering epochs ranging from 1978 to 2021, as we…
The spatially offset quasar E1821+643: New evidence for gravitational recoil
Yashashree Jadhav, Andrew Robinson, Triana Almeyda +2
A galaxy merger is expected to cause the formation of a supermassive black hole (SMBH) binary, which itself eventually coalesces through the anisotropic emission of gravitational w…
AGNIFS survey of local AGN: GMOS-IFU data and outflows in 30 sources
D. Ruschel-Dutra, T. Storchi-Bergmann, A. Schnorr-Müller +6
We analyse optical datacubes of the inner kiloparsec of 30 local () active galactic nuclei (AGN) hosts that our research group, AGNIFS, has collected over the past decade…
Spectropolarimetry of NGC3783 and Mrk509: Evidence for powerful nuclear winds in Seyfert 1 Galaxies
P. Lira, M. Kishimoto, R. W. Goosmann +6
We present results from high signal-to-noise optical spectropolarimetric observations of the Seyfert 1 galaxies NGC783 and Mrk509 in the 3500-7000 A range. We find complex structur…
Spectropolarimetry of low redshift Quasars: origin of the polarization and implications for black hole mass estimates
Alessandro Capetti, Ari Laor, Ranieri D. Baldi +2
We present the results of high signal-to-noise ratio VLT spectropolarimetry of a representative sample of 25 bright type 1 AGN at z<0.37, of which nine are radio-loud. The sample c…
