The peculiar kinematics of the multiple populations in the globular cluster Messier 80 (NGC 6093)
Sebastian Kamann, Emanuele Dalessandro, Nate Bastian +10
We combine MUSE spectroscopy and Hubble Space Telescope ultraviolet (UV) photometry to perform a study of the chemistry and dynamics of the Galactic globular cluster Messier 80 (M8…
Imprints of Evolution on the Internal Kinematics of Globular Clusters
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +2
Globular clusters are collisional systems, meaning that the stars inside them interact on timescales much shorter than the age of the Universe. These frequent interactions transfer…
Hunting for the Dark Matter Wake Induced by the Large Magellanic Cloud
Nicolas Garavito-Camargo, Gurtina Besla, Chervin F. P Laporte +3
Satellite galaxies are predicted to generate gravitational density wakes as they orbit within the dark matter (DM) halos of their hosts, causing their orbits to decay over time. Th…
Globular cluster number density profiles using Gaia DR2
T. J. L. de Boer, M. Gieles, E. Balbinot +4
Using data from Gaia DR2, we study the radial number density profiles of the Galactic globular cluster sample. Proper motions are used for accurate membership selection, especially…
