In particular, since the pioneering theoretical work of Dekel and Silk (1986), the potential role of galactic winds, induced by kinetic energy input from supernova explosions, has been quite often discussed in the literature. However, despite a tremendous amount of theoretical (eg Efstathiou 2002), numerical (eg MacLow and Ferrara ) and observational (eg Kaufman et al 2002) work on the subject, this issue remains rather elusive yet. Recently Garnett (2002), based on observations of metallicity in gas-rich galaxies (spirals and irregulars) suggested that IF the initial stellar mass function remains constant, THEN galactic mass loss, PREFERENTIALLY of metals, HAS to take place; in fact, a preliminary calculation suggest that the metal loss has to be related (inversely proportional) to the gravitational potential well of the galaxy, the small galaxies losing more metals. This important result has to be substantiated both observationally and theoretically: observationally, by finding whether such metal-enriched galactic winds do indeed occur (e.g. through X-ray observations, see Heckmann et al. 2002) and theoretically by the development of galactic evolution models incorporating such effects; those models should not only reproduce the aforementioned observations, but also a multitude of other observational data (chemical and spectrophotometric) concerning those galaxies. Our team has a long experience in modelling the chemical and spectrophotometric evolution of galaxies, in particular of late type. We are using consistent models of galaxy evolution, with both chemical and spectrophotometric evolution followed by means of metallicity dependent stellar lifetimes, tracks, spectra and chemical yields. In a series of papers (Boissier, Prantzos et al....) we presented models of galactic evolution, CALIBRATED on the Milky Way disk and reproducing all the major observables of disk galaxies (Tully-Fisher relation, colour-colour and colour magnitude diagrams, metallicity vs magnitude and gas fraction, as well as star formation vs magnitude, etc). The success of the models relied mainly on the assumption that small disks are YOUNGER than massive ones. That assumption goes opposite to the one favoured these days by hierachical models of galaxy formation, which has serious problems in reproducing properties of present day galaxies, like the colour-magnitude relationship. It has been claimed that feed-back can cure all those problems, but detailed investigation (see van den Bosch 2002 and Bell et al. 2003) showed that such claims are not founded. Still, the success of hierarchical paradigm in explaing large scale properties of galaxies (Ref ) suggest that some baryonic physics mechanism managed to "invert the hierarchy": despite the fact that small non-baryonic dark haloes were formed before the massive ones, the baryons of the massive galaxies turned into stars before those of their smaller cousins. We intend to refine our models in order to study those aspects of galaxy evolution, in the framework of the proposed network; such an effort requires in fact to incorporate dynamical aspects in the models and we would profit ----------------------------------------------------------------------------- Michel Fioc (IAP): ~~~~~~~~~~~~~ fioc@iap.fr 33(0)1 44 32 81 79 topic of interest: - Galactic chemical evolution, galaxy formation and evolution and Stellar population synthesis... and wish to benefit from (collaborate) - Detail studies of nearby regions of violent star formation, i.e. Giant extragalactic HII regions and HII galaxies - Dust enshrouded star forming regions.
