The last years saw numerous detections of substructure in the Galactic halo, largely due to wide area surveys like the Sloan Digital Sky Survey (SDSS) or the Two Micron All Sky Survey (2MASS). The analysis of SDSS data revealed the `Field of Streams' which encompasses, among other features, the broad and extended Sagittarius tidal stream as well as

The influence of the orientation angles of the target nucleus symmetry axis, relative to the beam direction, on the production of the evaporation residues is investigated for the 48Ca+154Sm reaction as a function of beam energy. At low energies (Ec.m. 180 MeV, σER ranges approximately 0.1-10 mb because the fission barrier for a compound nucleus

We present deep and accurate optical photometry of the Local Group starburst galaxy IC 10. The photometry is based on two sets of images collected with the Advanced Camera for Surveys and with the Wide Field Planetary Camera 2 on board the Hubble Space Telescope. We provide new estimates of the tip of the red giant branch (TRGB) magnitude

Aims: This work aims to provide a theoretical formulation of surface brightness fluctuations (SBF) in the framework of probabilistic population synthesis models that have no deterministic relations between the different stellar components of a population but only relations on average, and to distinguish between the different distributions involved
