Blowing star formation away in AGN hosts (BAH) -- V: The Feeding-Feedback Cycle in local AGNs as revealed by their stellar populations
Rogério Riffel, Rogemar A. Riffel, Gabriel L. Souza-Oliveira +9
We present a spatially resolved analysis of the stellar populations in the inner kiloparsec of NGC 3884, 3C 293, and CGCG 012-070. Using near-infrared spectroscopy, we reconstruct…
Radio emission in star-forming galaxies: connection to restarted or relic AGN activity
Marco Albán, Dominika Wylezalek, Pranav Kukreti +2
Increasing evidence shows that AGN with radio detections have more perturbed ionized gas kinematics and higher outflow detection rates, suggesting a link between radio emission and…
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…
Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs
Thayse A. Pacheco, Paula R. T. Coelho, Lucimara P. Martins +8
Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, su…
Blowing Star Formation Away in AGN Hosts (BAH) -- III. Serendipitous discovery of a star-forming galaxy lensed by the galactic bulge of CGCG 012-070 using JWST NIRSpec
Rogemar A. Riffel, Carlos R. Melo-Carneiro, Gabriel Luan Souza-Oliveira +10
We report the detection of a gravitationally lensed galaxy by the nearby spiral galaxy CGCG 012-070 () using Integral Field Unit (IFU) observations with the Near-Infrare…
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…
