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…

Near-infrared diagnostic diagrams of the gas ionization sources in nearby galaxies: a JWST NIRSpec view

J. H. Costa-Souza, Luis Colina, Rogemar A. Riffel +6

Buried active galactic nuclei and obscured young stellar clusters pose significant challenges to traditional optical diagnostic diagrams. Therefore, developing new tools to trace t…

Impact of AGN and nuclear star formation on the ISM turbulence of galaxies: Insights from JWST/MIRI spectroscopy

Rogemar A. Riffel, Luis Colina, José Henrique Costa-Souza +31

Active galactic nuclei (AGN), star formation (SF), and galaxy interactions can drive turbulence in the gas of the ISM, which in turn plays a role in the SF within galaxies. The imp…

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…

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…

Blowing star formation away in AGN Hosts (BAH) -- II. Investigating the origin of the H2 emission excess in nearby galaxies with JWST MIRI

Rogemar A. Riffel, Gabriel L. Souza-Oliveira, José Henrique Costa-Souza +4

We use James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) medium-resolution spectrometer (MRS) observations of 3C 293 (UGC 8782), CGCG 012-070 and NGC 3884 to investi…
