... Perhaps the most interesting satellites in this group are the ones sent into distant orbits, some of them extending well past the Moon--e.g. the WIND spacecraft pictured here. Among them is a long series of IMP s (Interplanetary Monitoring Platforms) which sampled the Earth's distant magnetic environment, the magnetosphere, and the surrounding interplanetary region; IMP-8 is still returning good data, more than 20 years after its launch. ...

The goal is to bring together two communitities: the one working on star formation (mostly galactic) and the one working on the formation of young massive clusters (mostly extra-galactic). We will link galactic with extra-galactic work, optical/NIR techniques with sub-mm/mm/radio ones, the formation of stars with the one of massive star clusters - observations and theory. ...

... Your main research interests concern the computer modelling of galaxy formation. ... The observers think that they are smart, but it is only thanks to these new telescopes that all the exciting recent progress has been made in the study of the high redshift universe. ... By redshift ten, some knots (where filaments and sheets join) are getting dense enough to form galaxies, and the first light in the universe switches on. ... By redshift 5, clusters of galaxies are centred on these knots. ...
