    • Bipolar ionization cones in the extended narrow-line region of nearby QSO2s 

      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 ...

    • OzDES multi-object fibre spectroscopy for the Dark Energy Survey : results and second data release 

      Lidman, Chris; Santiago, Basilio Xavier; DES Collaboration (2020) [Artigo de periódico]
      We present a description of the Australian Dark Energy Survey (OzDES) and summarize the results from its 6 years of operations. Using the 2dF fibre positioner and AAOmega spectrograph on the 3.9-m Anglo-Australian Telescope, ...
