    • A Megacam Survey of Outer Halo Satellites. VI. The Spatially resolved Starformation History of the Carina ... 
      Santana Rojas, Felipe; Muñoz Vidal, Ricardo Rodrigo; de Boer, T. J. L.; Simon, Joshua D.; Geha, Marla; Coté, Patrick; Guzmán Fernández, Andrés; Stetson, Peter B.; Djorgovski, S. George (IOP, 2016)
      We present the spatially resolved star-formation history (SFH) of the Carina dwarf spheroidal galaxy, obtained from deep, wide-field g and r imaging and a metallicity distribution from the literature. Our photometry covers ...
    • A MegaCam Survey of Outer Halo Satellites. VII. A Single Sérsic Index versus Effective Radius Relation for ... 
      Marchi-Lasch, Sebastián; Muñoz Vidal, Ricardo Rodrigo; Santana, Felipe A.; Carballo Bello, Julio A.; Chanamé, Julio; Geha, Marla; Simon, Joshua D.; Stetson, Peter B.; Djorgovski, S. G. (Institute of Physics Publishing, 2019)
      In this work, we use structural properties of the Milky Way's outer halo (R G > 25 kpc) satellites (dwarf spheroidal galaxies, ultra-faint dwarf (UFD) galaxies and globular clusters (GCs)) derived from deep, wide-field, ...
    • Multiple chemodynamic stellar populations of the Ursa Minor dwarf spheroidal galaxy 
      Pace, Andrew B.; Kaplinghat, Manoj; Kirby, Evan; Simon, Joshua D.; Tollerud, Erik; Muñoz Vidal, Ricardo Rodrigo; Côte, Patrick; Djorgovski, S. G.; Geha, Marla (Oxford University Press, 2020)
      We present a Bayesian method to identify multiple (chemodynamic) stellar populations in dwarf spheroidal galaxies (dSphs) using velocity, metallicity, and positional stellar data without the assumption of spherical symmetry. ...
