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…
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…
Metallicity of Active Galactic Nuclei from ultraviolet and optical emission lines-II. Revisiting the metallicity calibration and its implications
O. L. Dors, C. B. Oliveira, M. V. Cardaci +7
In this study, a new semi-empirical calibration is proposed between ultraviolet emission lines (\ion{C}{iii}], \ion{C}{iv}, \ion{He}{ii}]) of…
Metallicity of Active Galactic Nuclei from ultraviolet and optical emission lines I: Carbon abundance dependence
O. L. Dors, C. B. Oliveira, M. V. Cardaci +9
Metallicity () estimates based on ultraviolet (UV) emission lines from the narrow-line regions (NLRs) of active galactic nuclei (AGNs) have been found to differ from those deriv…
