The central density cusp of the Sagittarius dwarf spheroidal galaxy
L. Monaco, M. Bellazzini, F. R. Ferraro +1
We present an analysis of the density profile in the central region of the Sagittarius dwarf spheroidal galaxy. A strong density enhancement of Sgr stars is observed. The position…
The small Blue Straggler star population in the dense Galactic Globular Cluster NGC 6752
E. Sabbi, F. R. Ferraro, A. Sills +1
We have used high resolution WFPC2-HST and wide field ground-based observations to construct a catalog of blue straggler stars (BSS) which spans the entire radial extent of the glo…
The distance to the Leo I dwarf spheroidal galaxy from the Red Giant Branch Tip
M. Bellazzini, N. Gennari, F. R. Ferraro +1
We present V and I photometry of a 9.4 arcmin X 9.4 arcmin field centered on the dwarf spheroidal galaxy Leo I. The I magnitude of the tip of the Red Giant Branch is robustly estim…
The distance to the Sgr dwarf spheroidal galaxy from the Red Giant Branch Tip
L. Monaco, M. Bellazzini, F. R. Ferraro +1
We derived the distance to the central region of the Sagittarius dwarf spheroidal galaxy from the Red Giant Branch Tip. The obtained distance modulus is , cor…
The calibration of the RGB Tip as a Standard Candle: Extension to Near Infrared colors and higher metallicity
M. Bellazzini, F. R. Ferraro, A. Sollima +2
New empirical calibrations of the Red Giant Branch Tip in the I,J,H and K bands based on two fundamental pillars, namely omega Centauri and 47 Tucanae, have been obtained by using…
Discovery of an anomalous Sub Giant Branch in the Color Magnitude Diagram of omega Centauri
F. R. Ferraro, A. Sollima, E. Pancino +4
Using deep high-resolution multi-band images taken with the Very Large Telescope and the Hubble Space Telescope, we discovered a new anomalous sequence in the Color Magnitude Diagr…
