The globular cluster NGC7492 and the Sagittarius tidal stream: together but unmixed
Julio A. Carballo-Bello, Jesús M. Corral-Santana, Márcio Catelan +7
We have derived from VIMOS spectroscopy the radial velocities for a sample of 71 stars selected from CFHT/Megacam photometry around the Galactic globular cluster NGC7492. In the re…
Tails and streams around the Galactic globular clusters NGC1851, NGC1904, NGC2298 and NGC2808
Julio A. Carballo-Bello, David Martínez-Delgado, Camila Navarrete +4
We present DECam imaging for the peculiar Galactic globular clusters NGC1851, NGC1904 (M79), NGC2298 and NGC2808. Our deep photometry reveals that all the clusters have an importan…
The global mass functions of 35 Galactic globular clusters: I. Observational data and correlations with cluster parameters
Antonio Sollima, Holger Baumgardt
We have derived the global mass functions of a sample of 35 Galactic globular clusters by comparing deep Hubble Space Telescope photometry with suitable multimass dynamical models.…
