The Universe has been existing for 15 to 20 billion years. After the period of galaxy assembling by hierarchical merging of elementary bricks, the stellar formation becomes less intense. MIGALE studies this recent period (from z ~ 1 to z ~ 0), during which the star formation rate decreases while most of the present stars are formed. The objective is to understand the evolution of galaxies, of their environment, and in particular the history of stellar formation and morphological evolution.

The study of galaxy evolution between z ~ 1 and the local Universe requires a comparison of multi-parametric samples taken at different distances. The objective of the MIGALE project is to provide the software tools which will be part of the development of a Virtual Observatory. Such a V.O. will allow astronomers of the whole world to access the WEB available data from their terminal.
Users will submit requests to extract and process data from various servers throughout the world; results will be sent back by the servers using a standardized format. These tools will be developed with in view inter-operability and re-usability.

MIGALE supplies users with :

the Pleinpot software, backbone of the project. This package with free distributed sources contains the infrastructure and all the utilities with which the database and analysis tools have been built.
databases, including HyperLeda . Other databases will be publicly available .

MIGALE supports scientific collaborations, based e.g. on the VLT GIRAFFE Guaranteed Time Observations.
MIGALE adapts the Pleinpot software to the specific needs of these programmes. It is for instance involved in the determination of the velocity field from IFU data. It controls the reliability of these tools and participates to their distribution.
