      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 ...

      Raimann, Daniel Iunes; Storchi-Bergmann, Thaisa; Quintana, Henrique; Hunstead, Richard W.; Wisotzki, Lutz (2005) [Artigo de periódico]
      We investigate the nature of the continuum emission and stellar populations in the inner 1–3 kpc of a complete sample of 24 southern radio galaxies, and we compare the results with a control sample of 18 non-active early-type ...

C.; Tarle, Gregory; Thomas, D.; Walker, Alistair; DES Collaboration (2017) [Artigo de periódico]
      We present a study of quasar selection using the supernova fields of the Dark Energy Survey (DES). We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completeness and efficiency ...
