    • The brightest group galaxies and their large-scale environment 

      Luparello, Heliana E.; Lares Harbin Latorre, Marcelo; Paz, Dante Javier.; Yaryura, Claudia Yamila.; Lambas, Diego García.; Padilla, Nelson D. (Asociación Argentina de Astronomía, 2015)
      We use a sample of galaxy groups in SDSS data to study their brightestgalaxies (BGG), separating groups according to their large scale environment. The statistical properties of the BGG depend on the surrounding environment ...

    • Interactions of Galaxies: Systems with Tidal Bridges 

      (2015)
      In this work we present a sample of elliptical interacting galaxy pairs connected by a bridge, obtained from a visual classification of a pair catalogue dereived from the data of the 7th Sloan Digital Sky Survey (SDSS-DR7). ...

    • A project to constrain emission from giant gaseous shells around high redshift radio galaxies 

      Moyano, Martín Manuel; Humphrey, Andrew J.; Merlo, David Constantino (Asociación Argentina de Astronomía, 2015)
      Around half of the radio galaxies (radio-loud, type 2 quasars) at 2 are known to show strong Ly absorption features in their spectra, with a spatial extent at least as large as the background Ly nebulae closely associated ...
