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…
A Survey of M31 Globular Clusters using WFPC2 on board HST
R. M. Rich, C. E. Corsi, M. Bellazzini +3
We report new, as yet unpublished HST/WFPC2 V, I photometry of 9 globular clusters in M31. These are part of a total sample of 19 clusters on M31 with well observed CMDs from HST.…
The RR Lyrae variables in M54 and the Sgr dwarf galaxy
Carla Cacciari, Michele Bellazzini, Samantha Colucci
We report on new B, V and I CCD photometry of the globular cluster M54 that was aimed at the study of its variable stars. With respect to the previous most recent work on M54 we ha…
