The Horizontal Branch of the Sculptor Dwarf galaxy
Maurizio Salaris, Thomas de Boer, Eline Tolstoy +2
We have performed the first detailed simulation of the horizontal branch of the Sculptor dwarf spheroidal galaxy by means of synthetic modelling techniques,taking consistently into…
A Double White-Dwarf Cooling Sequence in ω Centauri
A. Bellini, J. Anderson, M. Salaris +4
We have applied our empirical-PSF-based photometric techniques on a large number of calibration-related WFC3/UVIS UV-B exposures of the core of ω Cen, and found a well-defined spli…

Edouard J. Bernard, Matteo Monelli, Carme Gallart +9
We present the results of a new search for variable stars in the Local Group dwarf galaxy Leo A, based on deep photometry from the Advanced Camera for Surveys onboard the Hubble Sp…
