We discuss the use of gravitational wave sources as probes of cosmology. The inspiral and merger of a binary system, such as a pair of black holes or neutron stars, is extraordinarily bright in gravitational waves. By observing such systems it is...

Magnetization plays an important role in modern theories of the star-formation process. Slippage of neutrals relative to ions tied to magnetic fields in molecular cloud cores leads to a gravomagneto catastrophe in which the central regions formally...

In this talk I will present results on the study of circumnuclear star-forming rings based on integral-field SAURON and NIR SINFONI observations. I'll review the main kinematic properties of these features and their relation to the surrounding...

When extrasolar planets are observed to eclipse their parent stars, we are granted unprecedented access to their physical properties. It is only for these systems that we are permitted direct estimates of the planetary masses and radii, which in...

The similarity between the mass and spatial distributions of pre-stellar gas cores in star-forming clouds and young stars in clusters provides strong circumstantial evidence that these gas cores are the direct progenitors of individual stars. I...
