The Terzan 5 puzzle: discovery of a third, metal-poor component
L. Origlia, D. Massari, R. M. Rich +4
We report on the discovery of 3 metal-poor giant stars in Terzan 5, a complex stellar system in the the Galactic bulge, known to have two populations at [Fe/H]=-0.25 and +0.3. For…
Double Blue Straggler sequences in GCs: the case of NGC 362
E. Dalessandro, F. R. Ferraro, D. Massari +8
We used high-quality images acquired with the WFC3 on board the HST to probe the blue straggler star (BSS) population of the Galactic globular cluster NGC 362. We have found two di…
The velocity dispersion profile of NGC 6388 from resolved-star spectroscopy: no evidence of a central cusp and new constraints on the black hole mass
B. Lanzoni, A. Mucciarelli, L. Origlia +8
By combining high spatial resolution and wide-field spectroscopy performed, respectively, with SINFONI and FLAMES at the ESO/VLT we measured the radial velocities of more than 600…
