    • 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) [Journal article]
      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) [Journal article]
      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) [Journal article]
      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. C.; Abdalla, Filipe B.; Allam, Sahar S.; Banerji, M.; Benoit-Lévy, Aurélien; Bertin, Emmanuel; Brooks, D.; Carnero Rosell, Aurelio; Carrasco Kind, Matías; Carretero Palacios, Jorge; Cunha, Carlos Eduardo; Costa, Luiz N. da; Desai, S.; Diehl, H. Thomas; Dietrich, Jörg P.; Evrard, August E.; Fausti Neto, Angelo; Flaugher, Brenna; Frieman, Joshua A.; Gerdes, David W.; Goldstein, Daniel Abraham; Gruen, Daniel; Gruendl, Robert A.; Gutierrez, Gaston R.; Honscheid, K.; James, David J.; Kuehn, Kyler; Kuropatkin, Nikolay P.; Lima, Marcos Vinicius Borges Teixeira; Maia, Marcio Antonio Geimba; Marshall, Jennifer L.; Melchior, Peter M.; Miquel, Ramon; Mohr, Joseph J.; Ogando, Ricardo L.C.; Plazas Malagón, Andrés Alejandro; Romer, Anita K.; Rooney, Philip J.; Sanchez-Alvaro, Eusebio; Santiago, Basilio Xavier; Scarpine, Victor Emanuel; Sevilla Noarbe, Ignacio; Smith, Robert Christopher; Soares-Santos, Marcelle; Sobreira, Flávia; Suchyta, Eric; Tarle, Gregory; Thomas, D.; Tucker, Douglas L.; Walker, Alistair; DES Collaboration (2017) [Journal article]
      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 

      Mallmann, Nícolas Dullius; Riffel, Rogério; Storchi-Bergmann, Thaisa; Rembold, Sandro Barboza; Riffel, Rogemar André; Schimoia, Jáderson da Silva; Costa, Luiz N. da; Avila-Reese, Vladimir; Sánchez, Sebastián F.; Machado, Alice Deconto; Cirolini, Rafael Fernando; Ilha, Gabriele da Silva; Nascimento, Janaina Correa do (2018) [Journal article]
      We present spatially resolved stellar population (SP) age maps, average radial profiles and gradients for the first 62 active galactic nuclei (AGN) observed with Sloan Digital Sky Survey (SDSS)-IV Mapping Nearby Galaxies ...
