Hubble Space Telescope proper motion (HSTPROMO) catalogs of Galactic globular clusters. III. Dynamical distances and mass-to-light ratios
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +1
We present dynamical distance estimates for 15 Galactic globular clusters and use these to check the consistency of dynamical and photometric distance estimates. For most of the cl…
HST astrometry in the 30 Doradus region: measuring proper motions of individual stars in the Large Magellanic Cloud
I. Platais, R. P. van der Marel, D. J. Lennon +5
We present measurements of positions and relative proper motions in the 30 Doradus region of the Large Magellanic Cloud (LMC). We detail the construction of a single-epoch astromet…
Rapidly rotating second-generation progenitors for the blue hook stars of ω Cen
Marco Tailo, Francesca D'Antona, Enrico Vesperini +9
Horizontal Branch stars belong to an advanced stage in the evolution of the oldest stellar galactic population, occurring either as field halo stars or grouped in globular clusters…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. III. A quintuple stellar population in NGC2808
A. P. Milone, A. F. Marino, G. Piotto +9
In this study we present first results from multi-wavelength Hubble Space Telescope (HST) observations of the Galactic globular cluster GC NGC2808 as an extension of the Hubble Spa…
UV Insights into the Complex Populations of M 87 Globular Clusters
A. Bellini, A. Renzini, J. Anderson +7
We have imaged with HST's WFC3/UVIS the central 2.72.7 arcmin region of the giant elliptical galaxy M 87, using the ultraviolet filter F275W. In combination with archiv…
High-precision astrometry with VVV. I. An independent reduction pipeline for VIRCAM@VISTA
M. Libralato, A. Bellini, L. R. Bedin +6
We present a new reduction pipeline for the VIRCAM@VISTA detector and describe the method developed to obtain high-precision astrometry with the VISTA Variables in the Vía Láctea (…
Hubble Space Telescope proper motion (HSTPROMO) catalogs of Galactic globular clusters. II. Kinematic profiles and maps
Laura L. Watkins, Roeland P. van der Marel, Andrea Bellini +1
We present kinematical analyses of 22 Galactic globular clusters using the Hubble Space Telescope proper motion (HSTPROMO) catalogues recently presented in Bellini et al. (2014). F…
