    Dynamical evolution of globular cluster systems in clusters of galaxies - I. The case of NGC 1404 in the Fornax cluster
    We investigate, via numerical simulations, the tidal stripping and accretion of globular clusters (GCs). In particular, we focus on creating models that...
  • Publication
    Dynamical evolution of two associated galactic bars
    We study the dynamical interactions of mass systems in equilibrium under their own gravity that mutually exert and experience gravitational forces. The method...
  • Publication
    Dynamical masses and non-homology of massive elliptical galaxies grown by dry mergers
    We study whether dry merger-driven size growth of massive elliptical galaxies depends on their initial structural concentration, and analyse the validity of the...

    Dynamical model of the grand-design spiral galaxy NGC 157.
    Numerical simulations of the interstellar medium under the action of a density wave provide an accurate method for determining the positions of the main...

    Dynamical Structure of the Molecular Interstellar Medium in an Extremely Bright, Multiply Lensed z ~= 3 Submillimeter Galaxy Discovered with Herschel
    We report the detection of CO(J = 5 → 4), CO(J = 3 → 2), and CO(J = 1 → 0) emission in the strongly lensed, Herschel/SPIRE-selected submillimeter galaxy (SMG)...

    Early science with the Large Millimeter Telescope: a 1.1 mm AzTEC survey of red-Herschel dusty star-forming galaxies
    We present Large Millimeter Telescope (LMT)/AzTEC 1.1 mm observations of ~100 luminous high-redshift dusty star-forming galaxy candidates from the $\sim 600\,$...

    Early science with the LMT: molecular torus in UGC 5101
    As part of the Early Science Large Millimeter Telescope projects, we report the detection of nine double-peaked molecular lines, produced by a rotating...

    Early-type dwarf galaxies with multicomponent stellar structure: Are they remnants of disc galaxies strongly transformed by their environment?
    Context. The surface brightness distribution of ~30-40% of the early-type dwarf galaxies with - 18 ≤ MB ≤ -15 in the Virgo and the Coma clusters is fitted by...

    Early-type galaxies have been the predominant morphological class for massive galaxies since only z ˜ 1
    Present-day massive galaxies are composed mostly of early-type objects. It is unknown whether this was also the case at higher redshifts. In a hierarchical...
