The Nuclear Structure of the Sagittarius Dwarf Spheroidal Galaxy
Lorenzo Monaco, Michele Bellazzini, Francesco R. Ferraro +1
We present a study of the central parts of the Sagittarius dwarf spheroidal galaxy (Sgr). We found a clear overdensity of Sgr's stars around M~54 (hereafter NS). NS is well represe…
Globular Clusters in the Sgr Stream and other structures
M. Bellazzini, R. Ibata, F. R Ferraro
The possible association of Galactic globular clusters with the Sgr Stream is shortly reviewed at the light of the most recent observations of the Stream. >= 20 % of the Galactic g…
Building up the Galactic Halo: The Sagittarius dSph and the globular cluster M22
L. Monaco, F. R. Ferraro, M. Bellazzini +1
The Sagittarius dwarf spheroidal (Sgr) and a few paculiar Galactic Globular Clusters (GGC) can be considered as building blocks of theGalactic Halo. We present a series of results…
The RGB Bump in dwarf Spheroidal galaxies: discovery and perspectives
Michele Bellazzini
I report on the recent discoveries of the Red Giant Branch Bump(s) in many dwarf Spheroidal galaxies of the Local Group. The perspectives for the use of this new observational feat…
Wide Field Imaging of the Sextans Dwarf Spheroidal Galaxy
E. Pancino, M. Bellazzini, F. R. Ferraro
We present wide field multiband photometry of the very low surface brightness dwarf Spheroidal galaxy (dSph) Sextans. We have found convincing evidence for the presence of multiple…
A new calibration of the RGB Tip as a Standard Candle
Michele Bellazzini, Francesco R. Ferraro, Elena Pancino
We have obtained an accurate estimate of the absolute I magnitude of the Tip of the Red Giant Branch (M_I(TRGB)) for the globular cluster Omega Cen, based {\em (a)} on the largest…
