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…

Determining star formation rates in AGN hosts from strong optical emission lines

Maitê S. Z. de Mellos, Rogemar A. Riffel, Jaderson S. Schimoia +11

The influence of Active Galactic Nuclei (AGN) on star formation within their host galaxies remains a topic of intense debate. One of the primary challenges in quantifying the star…

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…

Active galactic nuclei winds as the origin of the H emission excess in nearby galaxies

Rogemar A. Riffel, Nadia L. Zakamska, Rogerio Riffel

In most galaxies, the fluxes of rotational H2 lines strongly correlate with star formation diagnostics (such as polycyclic aromatic hydrocarbons, PAH), suggesting that H2 emission…

The Stellar Spectral Features of Nearby Galaxies in the Near-Infrared: Tracers of Thermally-Pulsing Asymptotic Giant Branch Stars?

Rogério Riffel, Rachel E. Mason, Lucimara P. Martins +12

We analyze the stellar absorption features in high signal-to-noise ratio near-infrared (NIR) spectra of the nuclear region of 12 nearby galaxies, mostly spirals. The features detec…
