      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 ...
    • On the black hole mass of the γ-ray emitting narrow-line Seyfert 1 galaxy 1H 0323+342 

      Landt, Hermine; Ward, Martin John; Baloković, Mislav; Kynoch, Daniel; Storchi-Bergmann, Thaisa; Boisson, Catherine; Done, Chris; Schimoia, Jáderson da Silva; Stern, Daniel (2017) [Artigo de periódico]
      Narrow-line Seyfert 1 galaxies have been identified by the Fermi Gamma-Ray Space Telescope as a rare class of γ -ray emitting active galactic nuclei. The lowest redshift candidate among them is the source 1H 0323+342. Here ...
    • The first spectroscopic dust reverberation programme on active galactic nuclei : the torus in NGC 5548 

      Landt, Hermine; Ward, Martin John; Kynoch, Daniel; Packham, Christopher; Ferland, Gary J.; Lawrence, Andy; Pott, Jörg-Uwe; Esser, Johannes; Horne, Keith; Starkey, David A.; Malhotra, Deepak; Fausnaugh, Michael; Peterson, Bradley M.; Wilman, Richard J.; Riffel, Rogemar André; Storchi-Bergmann, Thaisa; Barth, Aaron J.; Villforth, Carolin; Winkler, Hartmut (2019) [Artigo de periódico]
      We have recently initiated the first spectroscopic dust reverberation programme on active galactic nuclei in the near-infrared. Spectroscopy enables measurement of dust properties, such as flux, temperature, and covering ...
