      Storchi-Bergmann, Thaisa; Oliveira, Bruno Dall'Agnol de; Micchi, L. F. Longo; Schmitt, Henrique Roberto; Fischer, Travis C.; Kraemer, S. B.; Crenshaw, Daniel Michael; Maksym, W. Peter; Elvis, Martin; Fabbiano, Giuseppina; Colina, Luis (2018) [Artigo de periódico]
      We have used narrowband [O III] λλ4959, 5007 and Hα+[N II] λλ6548, 84 Hubble Space Telescope (HST) images of nine luminous (L[O III]>1042 erg s−1) type 2 QSOs with redshifts 0.1<z<0.5 in order to constrain the geometry of ...
    • Gauging the effect of supermassive black holes feedback on quasar host galaxies 

      Oliveira, Bruno Dall'Agnol de; Storchi-Bergmann, Thaisa; Kraemer, S. B.; Villar-Martín, Montse; Müller, Allan Schnorr; Schmitt, Henrique Roberto; Dutra, Daniel Ruschel; Crenshaw, Daniel Michael; Fischer, Travis C. (2021) [Artigo de periódico]
      In order to gauge the role that active galactic nuclei play in the evolution of galaxies via the effect of kinetic feedback in nearby QSO 2’s (z ∼ 0.3), we observed eight such objects with bolometric luminosities Lbol∼1046ergs−1 ...
    • Modelling the [Fe II] λ1.644 μm outflow and comparison with H2 and H+ kinematics in the inner 200 pc of NGC 1068 

      Barbosa, Fausto Kuhn Berenguer; Storchi-Bergmann, Thaisa; McGregor, Peter J.; Vale, Tibério Borges; Riffel, Rogemar André (2014) [Artigo de periódico]
      We map the kinematics of the inner (200 pc) narrow-line region (NLR) of the Seyfert 2 galaxy NGC 1068 using the instrument Near-infrared Integral Field Spectrograph and adaptive optics at the Gemini North telescope. Channel ...
    • Quantifying feedback from narrow line region outflows in nearby active galaxies II. Spatially resolved mass outflow rates for the QSO2 Markarian 34 

      Revalski, Mitchell; Dashtamirova, D.; Crenshaw, Daniel Michael; Kraemer, S. B.; Fischer, Travis C.; Schmitt, Henrique Roberto; Gnilka, C. L.; Schmidt, Jana G.; Elvis, Martin; Fabbiano, Giuseppina; Storchi-Bergmann, Thaisa; Maksym, W. Peter; Gandhi, Poshak (2018) [Artigo de periódico]
      We present spatially resolved mass outflow rate measurements (M˙ out) for the narrow line region of Markarian 34, the nearest Compton-thick type 2 quasar (QSO2). Spectra obtained with the Hubble Space Telescope and at ...
