... Previous: Image Processing of Digitized Spectral Data . ... The analysis of sequences of light curves spanning a long time interval (at least one or two decades) allows us to detect activity cycles, analogous to the solar 11-year cycle, inferring the overall properties of the stellar dynamos. ... Our parallel procedure was written in standard FORTRAN using the PVM library version 3 and exploits a networked system to perform the analysis of a sequence of N L light curves. ...

Rep ort by the ESA-ESO Working Group on Galactic p opulations, chemistry and dynamics Abstract Between the early 40s, when Baade showed the first evidence for the existence of two distinct stellar populations, and today, with our Galaxy surprising us with new substructures discovered almost on a monthly basis, it is clear that a remarkable progress has been achieved in our understanding of the Galaxy, of its structure and stellar populations, and of its chemical and dynamical signatures. Yet, some questions

... I will touch upon the following points: ­ fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; ­ prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; ­ apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; ­ old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
