    • A megacam survey of outer halo satellites. I. description of the survey 
      Muñoz Vidal, Ricardo Rodrigo; Cote, Patrick; Santana, Felipe; Geha, Marla; Simón, Joshua D.; Oyarzún, Grecco A.; Stetson, Peter B.; Djorgovski, S. G. (IOP Publishing, 2018-06-10)
      We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities-i.e., substructures classified as either globular clusters, classical dwarf ...
    • A megacam survey of outer halo satellites. III. Photometric and structural parameters 
      Muñoz Vidal, Ricardo Rodrigo; Cote, Patrick; Santana, Felipe; Geha, Marla; Simón, Joshua D.; Oyarzún, Grecco A.; Stetson, Peter B.; Djorgovski, S. G. (The American Astronomical Society, 2018-06-10)
      We present structural parameters from a wide-field homogeneous imaging survey of Milky Way satellites carried out with the MegaCam imagers on the 3.6 m Canada-France-Hawaii Telescope and 6.5 m Magellan-Clay telescope. Our ...
    • 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, ...
    • A survey for dwarf galaxy remnants around 14 globular clusters in the outer halo 
      Sollima, A.; Martínez Delgado, David; Muñoz Vidal, Ricardo Rodrigo; Carballo-Bello, J. A.; Valls-Gabaud, D.; Grebel, E. K.; Santana, F.; Cote, P.; Djorgovski, S. G. (Oxford University Press, 2018-06)
      We report the results of a systematic photometric survey of the peripheral regions of a sample of 14 globular clusters in the outer halo of the Milky Way at distances d(GC) > 25 kpc from the Galactic Centre. The survey is ...
    • 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. ...
