    • 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) ...

(1997) [Artigo de periódico]
      An 8 month monitoring campaign on the Seyfert 1 galaxy Fairall 9 has been conducted with the International Ultraviolet Explorer in an attempt to obtain reliable estimates of continuum-continuum and continuumÈemission-line ...
