    • A coronagraphic absorbing cloud reveals the narrow-line region and extended Lyman α emission of QSO J0823+0529 
      Fathivavsari, H.; Petitjean, P.; Noterdaeme, P.; Paris, I.; Finley, H.; López Morales, Sebastián; Srianand, R.; Sánchez, Paula (Royal Astronomical Society, 2015)
      We report long-slit spectroscopic observations of the quasar SDSS J082303.22+052907.6 (zC IV ∼ 3.1875), whose broad-line region (BLR) is partly eclipsed by a strong damped Lyman α (DLA; logN(H I) = 21.7) cloud. This ...
    • The Quest-La Silla AGN Variability Survey 
      Cartier Ugarte, Regis; Lira Teillery, Paulina; Coppi, Paolo; Sánchez, Paula; Arévalo, Patricia; Bauer, Franz; Rabinowitz, David; Zinn, Robert; Muñoz Vidal, Ricardo Rodrigo; Meza, Nicolás (IOP Pub., 2015)
      We present the characterization and initial results from the QUEST–La Silla active galactic nucleus (AGN) variability survey. This is an effort to obtain well-sampled optical light curves in extragalactic fields with ...
