• Active galactic nuclei signatures in Red Geyser galaxies from Gemini GMOS-IFU observations 

      Ilha, Gabriele da Silva; Riffel, Rogemar André; Ricci, Tiago Vecchi; Rembold, Sandro Barboza; Storchi-Bergmann, Thaisa; Riffel, Rogério; Roy, Namrata; Bundy, Kevin; Nemmen, Rodrigo S.; Schimoia, Jáderson da Silva; Costa, Luiz N. da (2022) [Artigo de periódico]
      Red Geysers are quiescent galaxies with galactic scale ionized outflows, likely due to low-luminosity active galactic nuclei (AGN). We used Gemini GMOS-IFU observations of the inner~1–3 kpc of nine Red Geysers selected ...
    • Precessing winds from the nucleus of the prototype Red Geyser? 

      Riffel, Rogemar André; Nemmen, Rodrigo S.; Ilha, Gabriele da Silva; Rembold, Sandro Barboza; Roy, Namrata; Storchi-Bergmann, Thaisa; Riffel, Rogério; Bundy, Kevin; Machado, Alice Deconto; Mallmann, Nícolas Dullius; Schimoia, Jáderson da Silva; Costa, Luiz N. da; Maia, Marcio Antonio Geimba (2019) [Artigo de periódico]
      Supermassive black holes (SMBHs) are present at the centre of most galaxies, with the related mass accretion processes giving origin to outflows in active galactic nuclei (AGNs). It has been presumed that only intense winds ...
    • SDSS IV MaNGA : star-formation driven biconical outflows in face-on galaxies 

      Bizyaev, D.; Chen, Yan-Mei; Shi, Yong; Roy, Namrata; Riffel, Rogério; Riffel, Rogemar André; Fernández-Trincado, José Gregorio (2022) [Artigo de periódico]
      We find 132 face-on and low inclination galaxies with central star formation driven biconical gas outflows (FSFB) in the SDSS MaNGA (Mapping Nearby Galaxies at APO) survey. The FSFB galaxies show either double peaked or ...
    • SDSS-IV MaNGA : star-formation-driven biconical outflows in the local universe 

      Bizyaev, D.; Chen, Yanmei; Shi, Yong; Riffel, Rogemar André; Riffel, Rogério; Diamond-Stanic, Aleksandar M.; Roy, Namrata (2019) [Artigo de periódico]
      We present a sample of 48 nearby galaxies with central, biconical outflows identified by the Mapping Nearby Galaxies at APO survey. All considered galaxies have star-formation-driven biconical (SFB) central outflows, with ...
