    • Hubble Space Telescope observations of extended [OIII]λ5007 emission in nearby QSO2s : new constraints on AGN host galaxy interaction 

      Fischer, Travis C.; Kraemer, S. B.; Schmitt, Henrique Roberto; Micchi, L. F. Longo; Crenshaw, Daniel Michael; Revalski, Mitchell; Vestergaard, Marianne; Elvis, Martin; Gaskell, C.M.; Hamann, Fred; Ho, Luis C.; Hutchings, John B.; Mushotzky, Richard; Netzer, Hagai; Storchi-Bergmann, Thaisa; Straughn, Amber N.; Turner, T.J.; Ward, Martin John (2018) [Artigo de periódico]
      We present a Hubble Space Telescope survey of extended [O III] λ5007 emission for a sample of 12 nearby (z < 0.12), luminous Type 2 quasars (QSO2s), which we use to measure the extent and kinematics of their AGNionized ...

    • Hubble Space Telescope observations of [O III] emission in nearby QSO2s : physical properties of the ionized outflows 

      Falcão, Anna Luiza Trindade; Kraemer, S. B.; Fischer, Travis C.; Crenshaw, Daniel Michael; Revalski, Mitchell; Schmitt, Henrique Roberto; Vestergaard, Marianne; Elvis, Martin; Gaskell, C.M.; Hamann, Fred; Ho, Luis C.; Hutchings, John B.; Mushotzky, Richard; Netzer, Hagai; Storchi-Bergmann, Thaisa; Turner, T.J.; Ward, M.J. (2021) [Artigo de periódico]
      We use Hubble Space Telescope/Space Telescope Imaging Spectrograph long-slit G430M and G750M spectra to analyse the extended [O iii] λ5007 emission in a sample of 12 nearby (z < 0.12) luminous (Lbol > 1.6 × 1045 erg s−1) ...

    • Powerful winds in high-redshift obscured and red quasars 

      Vayner, Andrey; Zakamska, Nadia L.; Riffel, Rogemar André; Alexandroff, Rachael; Cosens, Maren; Hamann, Fred; Perrotta, Serena; Rupke, David S.N.; Storchi-Bergmann, Thaisa; Veilleux, Sylvain; Walth, Gregory L.; Wright, Shelley A.; Wylezalek, Dominika (2021) [Artigo de periódico]
      Quasar-driven outflows must have made their most significant impact on galaxy formation during the epoch when massive galaxies were forming most rapidly. To study the impact of quasar feedback, we conducted rest-frame ...

(2014) [Artigo de periódico]
      We present the Data Release 10 Quasar (DR10Q) catalog from the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III. The catalog includes all BOSS objects that were targeted as quasar candidates ...
