    • Feeding versus feedback in NGC4151 probed with Gemini NIFS – II. Kinematics 

      Storchi-Bergmann, Thaisa; Lopes, Ramiro Duarte Simões; McGregor, Peter J.; Riffel, Rogemar André; Beck, Tracy; Martini, Paul (2010) [Artigo de periódico]
      We have used the Gemini Near-infrared Integral Field Spectrograph (NIFS) to map the gas kinematics of the inner ~200 × 500 pc 2 of the Seyfert galaxy NGC4151 in the Z, J, H and K bands at a resolving power of ≥5000 and ...

    • The black hole mass of NGC 4151. II. Stellar dynamical measurement from near-infrared field spectroscopy 

      Onken, Christopher Alan; Valluri, Monica; Brown, Jonathan S.; McGregor, Peter J.; Peterson, Bradley M.; Bentz, Misty Cherie; Ferrarese, Laura; Pogge, Richard William; Vestergaard, Marianne; Storchi-Bergmann, Thaisa; Riffel, Rogemar André (2014) [Artigo de periódico]
      We present a revised measurement of themass of the central black hole (MBH ) in the Seyfert 1 galaxyNGC4151. The new stellar dynamical mass measurement is derived by applying an axisymmetric orbit-superposition code to ...
