    • Constraints on the broad-line region properties and extinction in local Seyferts 

      Müller, Allan Schnorr; Davies, Richard I.; Korista, Kirk T.; Burtscher, Leonard; Rosario, David; Storchi-Bergmann, Thaisa; Contursi, Alessandra; Genzel, Reinhard; Gracia-Carpio, Javier; Hicks, Erin K. S.; Janssen, Annemieke; Koss, Michael; Lin, Ming-Yi; Lutz, Dieter; Maciejewski, Witold B.; Muller-Sanchez, Francisco; Orban de Xivry, Gilles; Riffel, Rogério; Riffel, Rogemar André; Schartmann, Marc; Sternberg, Amiel; Sturm, Eckhard; Tacconi, Linda J.; Veilleux, Sylvain; Ulrich, Otho Adam (2016) [Artigo de periódico]
      We use high-spectral resolution (R>8000) data covering 3800–13 000 Å to study the physical conditions of the broad-line region (BLR) of nine nearby Seyfert 1 galaxies. Up to six broad HI lines are present in each spectrum. ...

    • Photo-astrometric distances, extinctions, and astrophysical parameters for Gaia DR2 stars brighter than G = 18 

      Anders, Friedrich; Santiago, Basilio Xavier; Enke, Harry (2019) [Artigo de periódico]
      Combining the precise parallaxes and optical photometry delivered by Gaia’s second data release with the photometric catalogues of Pan-STARRS1, 2MASS, and AllWISE, we derived Bayesian stellar parameters, distances, and ...

    • The need for multicomponent dust attenuation in modeling nebular emission : constraints from SDSS-IV MaNGA 

      Ji, Xihan; Yan, Renbin; Bundy, Kevin; Boquien, Médéric; Schaefer, Adam L.; Belfiore, Francesco; Bershady, Matthew A.; Drory, Niv; Li, Cheng; Westfall, Kyle B.; Lin, Zesen; Bizyaev, D.; Law, David R.; Riffel, Rogério; Riffel, Rogemar André (2023) [Artigo de periódico]
      A fundamental assumption adopted in nearly every extragalactic study that analyzes optical emission lines is that the attenuation of different emission lines can be described by a single attenuation curve, scaled by a ...
