    • BAT AGN Spectroscopic Survey -IV. : near-infrared coronal lines, hidden broad lines and correlation with hard X-ray emission 

      Lamperti, Isabella; Koss, Michael; Trakhtenbrot, Benny; Schawinski, Kevin; Ricci, Claudio; Oh, Kyuseok; Landt, Hermine; Riffel, Rogério; Rodriguez-Ardila, Alberto; Gehrels, Neil C.; Harrison, Fiona Anne; Masetti, Nicola; Mushotzky, Richard; Treister, Ezequiel; Ueda, Yoshihiro; Veilleux, Sylvain (2017) [Artigo de periódico]
      We provide a comprehensive census of the near-infrared (NIR, 0.8–2.4 μm) spectroscopic properties of 102 nearby (z < 0.075) active galactic nuclei (AGN), selected in the hard X-ray band (14–195 keV) from the Swift-Burst ...

    • Morphology of AGN emission-line regions in SDSS-IV MaNGA survey 

      He, Zhicheng; Sun, Ai-Lei; Zakamska, Nadia L.; Wylezalek, Dominika; Kelly, Michael; Greene, Jenny E.; Rembold, Sandro Barboza; Riffel, Rogério; Riffel, Rogemar André (2018) [Artigo de periódico]
      Extended narrow-line regions (NLRs) around active galactic nuclei (AGN) are shaped by the distribution of gas in the host galaxy and by the geometry of the circumnuclear obscuration, and thus they can be used to test the ...

    • The complex jet- and bar- perturbed kinematics in NGC 3393 as revealed with ALMA and GEMINI–GMOS/IFU 

      Finlez, Carolina; Nagar, Neil M.; Storchi-Bergmann, Thaisa; Müller, Allan Schnorr; Riffel, Rogemar André; Lena, Davide; Mundell, Carole G.; Elvis, Martin (2018) [Artigo de periódico]
      NGC 3393, a nearby Seyfert 2 galaxy with nuclear radio jets, large-scale and nuclear bars, and a posited secondary supermassive black hole, provides an interesting laboratory to test the physics of inflows and outflows. ...

    • The evolution of active galactic nuclei in clusters of galaxies from the Dark Energy Survey 

      Bufanda, E.; Hollowood, D.; Jeltema, Tesla E.; Rykoff, Eli; Rozo, Eduardo; Martini, Paul; Abbott, Timothy M.

      The correlation between active galactic nuclei (AGNs) and environment provides important clues to AGN fuelling and the relationship of black hole growth to galaxy evolution. In this paper, we analyse the fraction of galaxies ...

    • The first 62 AGN observed with SDSS-IV MaNGA : II. resolved stellar populations
