    • The physical parameters of the evolving population of faint galaxies 

      Glazebrook, Karl; Abraham, Roberto G.; Santiago, Basilio Xavier; Ellis, Richard S.; Griffiths, Richard E. (1998) [Artigo de periódico]
      The excess number of blue galaxies at faint magnitudes is a subject of much controversy. Recent Hubble Space Telescope results have revealed a plethora of galaxies with peculiar morphologies tentatively identified as the ...

    • The relationship between the Sérsic law profiles measured along the major and minor axes of elliptical galaxies 

      Ferrari, Fabricio; Dottori, Horacio Alberto; Caon, Nicola; Nóbrega, Antonio José Farias; Pavani, Daniela Borges (2004) [Artigo de periódico]
      In this paper we discuss the reason why the parameters of the Sérsic model best-fitting the major axis light profile of elliptical galaxies can differ significantly from those derived for the minor axis profile.We show ...

    • The VISCACHA survey : II. Structure of star clusters in the Magellanic clouds periphery 

      Santos Junior, Joao Francisco Coelho dos; Maia, Francisco F. S.; Dias, Bruno Moreira de Souza; Kerber, Leandro de Oliveira; Piatti, Andres E.; Bica, Eduardo Luiz Damiani; Angelo, Mateus S.; Minniti, Dante; Pérez Villegas, Maria de Los Angeles; Roman-Lopes, Alexandre; Westera, Pieter; Fraga, Luciano; Quint, Bruno C.; Sanmartim, David (2020) [Artigo de periódico]
      We provide a homogeneous set of structural parameters of 83 star clusters located at the periphery of the Small Magellanic Cloud (SMC) and the Large Magellanic Cloud (LMC). The clusters’ stellar density and surface brightness ...

    • Time-slicing spiral galaxies with SDSS-IV MaNGA 

      Peterken, Thomas G.; Fraser-McKelvie, Amelia; Aragón-Salamanca, Alfonso; Merrifield, Michael; Kraljic, Katarina; Knapen, Johan Hendrik; Riffel, Rogério; Brownstein, Joel R.; Drory, Niv (2019) [Artigo de periódico]
      Spectra of galaxies contain a wealth of information about the stellar populations from which they are made. With integral field unit (IFU) surveys, such data can be used to map out stellar population properties across the ...

    • Understanding the two-dimensional ionization structure in luminous infrared galaxies : a near-IR integral field spectroscopy perspective 

      Colina, Luis; Piqueras López, Javier; Arribas Mocoroa, Santiago; Riffel, Rogério; Riffel, Rogemar André; Rodriguez-Ardila, Alberto; Pastoriza, Miriani Griselda; Storchi-Bergmann, Thaisa; Alonso-Herrero, Almudena; Sales, Dinalva Aires de (2015) [Artigo de periódico]
      We investigate the two-dimensional excitation structure of the interstellar medium (ISM) in a sample of luminous infrared galaxies (LIRGs) and Seyferts using near-IR integral field spectroscopy. This study extends to the ...
