AGN driven outflows in the OH absorber galaxy IRAS 19154+2704
C. Hekatelyne, Thaisa Storchi-Bergmann, Rogemar A. Riffel +4
We present a two-dimensional study of the gas distribution, excitation and kinematics of the OH absorber galaxy IRAS 19154+2704 using Gemini GMOS-IFU observations. Its continuum im…
The Kinematics and Ionization Structure of the Extended Emission Line Region of QSO E1821+643
Sara A. Rosborough, Andrew Robinson, Trent Seelig
The most luminous quasars are created by major, gas-rich mergers and E1821+643, an optically luminous quasar situated at the center of a cool-core cluster, appears to be in the lat…
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…
