Chemical abundances in Seyfert galaxies -- V. The discovery of shocked emission outside the AGN ionization axis
R. A. Riffel, O. L. Dors, M. Armah +9
We present maps for the electron temperature in the inner kpc of three luminous Seyfert galaxies: Mrk 79, Mrk 348, and Mrk 607 obtained from Gemini GMOS-IFU observations at spatial…
Determining star-formation rates in Active Galactic Nuclei hosts via stellar population synthesis
Rogério Riffel, Nicolas D. Mallmann, Gabriele S. Ilha +10
The effect of active galactic nuclei (AGN) feedback on the host galaxy, and its role in quenching or enhancing star-formation, is still uncertain due to the fact that usual star-fo…
Chemical abundances of Seyfert 2 AGNs IV. Composite models calculated by photoionization + shocks
O. L. Dors, M. Contini, R. A. Riffel +4
We build detailed composite models of photoionization and shock ionization based on the SUMA code to reproduce emission lines emitted from the Narrow Line Regions (NLR) of Seyfert…
The OH Megamaser galaxy IRAS11506-3851: an AGN and starformation revealed by multiwavelength observations
C. Hekatelyne, Rogemar A. Riffel, Thaisa Storchi-Bergmann +4
We present Gemini Multi-Object Spectrograph (GMOS) Integral Field Unit (IFU), Hubble Space Telescope (HST) and Very Large Array (VLA) observations of the OH Megamaser (OHM) galaxy…
Powerful ionized gas outflows in the interacting radio galaxy 4C +29.30
Guilherme S. Couto, Thaisa Storchi-Bergmann, Aneta Siemiginowska +2
We investigate the ionized gas excitation and kinematics in the inner kpc of the merger radio galaxy 4C +29.30. Using optical integral field spectroscopy wit…
Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program
John D. Silverman, Shenli Tang, Khee-Gan Lee +30
The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized…
Ionized and hot molecular outflows in the inner 500 pc of NGC1275
Rogemar A. Riffel, Thaisa Storchi-Bergmann, Nadia L. Zakamska +1
The role of feedback from Active Galactic Nuclei (AGN) in the evolution of galaxies is still not not fully understood, mostly due to the lack of observational constraints in the mu…
Gemini Near-Infrared Field Spectrograph Observations of the Seyfert 2 Galaxy Mrk 3: Feeding and Feedback on Galactic and Nuclear Scales
C. L. Gnilka, D. M. Crenshaw, T. C. Fischer +10
We explore the kinematics of the stars, ionized gas, and warm molecular gas in the Seyfert 2 galaxy Mrk~3 (UGC~3426) on nuclear and galactic scales with {\it Gemini} Near-Infrared…
SDSS-IV MaNGA: Kinematic Asymmetry as An Indicator of Galaxy Interaction in Paired Galaxies
Shuai Feng, Shi-Yin Shen, Fang-Ting Yuan +2
The interaction between galaxies is believed to be the main origin of the peculiarities of galaxies, which disturbs not only the morphology but also their kinematics. These disturb…
Evidence for an accreting massive black hole in He 2-10 from adaptive optics integral field spectroscopy
Rogemar A. Riffel
Henize 2-10 is a blue dwarf galaxy with intense star formation and one the most intriguing question about it is whether or not it hosts an accretingmassive black hole. We use H and…
