[0711.2932] Galactic Globular Clusters Database: a progress report
(by M. Castellani) The present status of Galactic Globular Clusters Database is briefly reviewed. The features implemented at the time writing are described, as well as plans for future improvements.
Near IR properties of GCs in the Galactic Bulge
We present the largest and homogeneous photometric survey of Globular Clusters (GCs) towards the Galactic Bulge obtained with the near-IR cameras SofI (NTT/ESO) and IRAC2b (MPI2.2m/ESO).
Upper limits on the central black hole masses of 47Tuc and NGC 6397 from radio c
We present upper limits on the masses of the putative central intermediate-mass black holes in two nearby Galactic globular clusters: 47Tuc (NGC 104), the second brightest Galactic globular cluster, and NGC 6397...
CCD Photometry of the Globular Cluster ESO 452-SC11
The globular cluster ESO 452-SC11 has been observed using Johnson V and Cousins I filters, and point-spread function photometry has been performed...
The extended star formation history of ω Centauri
For the first time, the abundances of a large sample of subgiant and turn-off region stars in ω Centauri have been measured, the data base being medium resolution spectroscopy from FORS2 at the VLT. Absolute iron abundances were derived for ∼400 member
CCD Photometry of the Globular Cluster ω Centauri. I. Metallicity of RR Ly
We present new measurements of the metallicity of 131 RR Lyrae stars in the globular cluster ω Centauri, using the hk index of the Caby photometric system....
New Metallicities of RR Lyrae Stars in ω Centauri: Evidence for a Non-He-e
We present new spectroscopic metal abundances for 74 RR Lyrae (RRL) stars in ω Cen obtained with FLAMES. The well-known metallicity spread is visible among the RRL variables.
Metallicities, Relative Ages, and Kinematics of Stellar Populations in ω C
We present results of an extensive spectroscopic survey of subgiant stars in the stellar system ω Cen. Using infrared Ca II triplet lines, we derived metallicities and radial velocities for more than 250 stars belonging to different stellar populations o
