Ionized Gas Outflows and Shock-Heated Emission in the Highly Inclined Active Galaxy CGCG 012-070
Lucas Ramos Vieira, Rogemar A. Riffel, Rogério Riffel +3
Active Galactic Nuclei (AGNs) exhibit excess mid-infrared H emission compared to star-forming galaxies, likely driven by outflows and shocks inferred from integrated spectra. W…
Investigating the clumpy star formation in an interacting dwarf irregular galaxy
Augusto E. Lassen, Ana L. Chies-Santos, Rogerio Riffel +9
Clumpy morphologies are more frequent in distant and low-mass star-forming galaxies. Therefore the less numerous nearby galaxies presenting kpc-sized clumps represent unique labora…
Blowing star formation away in AGN Hosts (BAH) -- IV: Feeding and feedback in 3C 293 observed with JWST NIRSpec
Maitê S. Z. de Mellos, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +5
We use JWST/NIRSpec observations of the radio galaxy 3C 293 to map the emission, extinction, and kinematics of hot molecular and ionized gas, as well as stellar kinematics, within…
A jet-driven bipolar outflow in NGC 1125
Astor João Schönell Júnior, Rogemar A. Riffel, Rogério Riffel +1
To study the role of the feedback from the Active Galactic Nuclei (AGNs) in the evolution of its host galaxy, we need observational constraints on 100 pc scales. We used the Gemini…
