Field OB stars are a crucial probe of star formation in extreme conditions. Properties of massive stars formed in relative isolation can distinguish between...

The luminosity function is not only crucial to know stellar density distribution in space, and thus to know the structure of the Galaxy, but it allows the...

In this article we first give a brief historically based survey of kinematic observations, essentially of rotation curves, of spiral galaxies produced as...

We present the first results from the mass modelling of the Sculptor dwarf spheroidal galaxy, using spectroscopic data from our VLT/FLAMES CaII triplet wide...

Star clusters provide a unique and powerful probe useful for studying the star formation histories of galaxies. In particular, the ages, metallicities and...

Superbubbles and large scale expansion in galaxies are important indicators of activity in galaxies: they are formed in starbursts and around active nuclei...

The kinematics of the inner zones of disc galaxies have recently been shown to be much more complicated than previously thou-ght. New instruments and more...

Bipolar planetary nebulae (BPNe) offer a unique opportunity to test models that aim to reproduce the PNe morphologies. In particular, kinematic studies of BPNe...
