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 Bologna Key Project on Omega Cen
F. R. Ferraro, E. Pancino, M. Bellazzini
In this contribution we schematically summarize a number of ongoing, coordinated spectro-photometric projects devoted to the study of the stellar population properties in Omega Cen…
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…
The Sagittarius Dwarf Galaxy Survey (SDGS): constraints on the Star Formation History of the Sgr dSph
M. Bellazzini, F. R. Ferraro, R. Buonanno
The main characteristics of a wide photometric survey of the Sgr dwarf spheroidal galaxy are shortly presented. V and I photometry has been obtained for ~ 90000 stars toward Sgr an…
