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…
