    • KINEMATICAL AND CHEMICAL VERTICAL STRUCTURE OF THE GALACTIC THICK DISK. II. A LACK OF DARK MATTER IN THE ... 
      Moni Bidin, Christian; Carraro, Giovanni; Méndez Bussard, René Alejandro; Smith, R. (IOP PUBLISHING LTD, 2012-05-20)
      We estimated the dynamical surface mass density Sigma at the solar position between Z = 1.5 and 4 kpc from the Galactic plane, as inferred from the kinematics of thick disk stars. The formulation is exact within the limit ...
    • On the local dark matter density 
      Moni Bidin, C.; Smith, R.; Carraro, Giovanni; Méndez Bussard, René Alejandro; Moyano, M. (EDP Sciences, 2015)
      Context. In 2012, we applied a three-dimensional formulation to kinematic measurements of the Galactic thick disk and derived a surprisingly low dark matter density at the solar position. This result was challenged by Bovy ...
    • Strong lensing in the inner halo of galaxy clusters 
      Sáez, C.; Campusano Brown, Luis; Cypriano, E. S.; Sodre, L.; Kneib, J. P. (Oxford Univ. Press, 2016)
      We present an axially symmetric formula to calculate the probability of finding gravitational arcs in galaxy clusters, being induced by their massive dark matter haloes, as a function of clusters redshifts and virial masses. ...
