  • Do globular clusters possess Dark Matter halos? A case study in NGC 2419 

    Ibata, Rodrigo, Carlo Nipoti, Antonio Sollima, Michele Bellazzini, et al. 2012. "Do globular clusters possess Dark Matter halos? A case study in NGC 2419." Monthly Notices of the Royal Astronomical Society 428(4):3648.
    We use recently published measurements of the kinematics, surface brightness and stellar mass-to-light ratio of the globular cluster NGC 2419 to examine the possibility that this Galactic halo satellite is embedded in a ...

  • Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics 

    Ibata, Rodrigo, Antonio Sollima, Carlo Nipoti, Michele Bellazzini, et al. 2011. "Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics." The Astrophysical Journal 743:43.
    We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ...
