• STECKMAP: STEllar Content and Kinematics via Maximum A Posteriori

  Reconstructing the star formation history of a galaxy from its integrated light allows to study the relation of galaxy evolution and formation with environment (cluster vs field galaxies), general morphology (spheroidal vs disc), morphological features (bars, spiral patterns, dust lanes in ellipticals). As such it is a very important tool. The principles of the reconstruction of galactic Star Formation History through Maximum A Posteriori likelihood are detailed in the publications STECMAP and STECKMAP . A package containing the implementation of these inverse methods and other tools in yorick is available for download. More details here .
