Work is underway at Birmingham on various aspects of galaxies, including the X-ray properties of spiral and elliptical galaxies, colour-magnitude relations, star formation properties and ages of galaxies in a range of environments, and the study of starburst, merging and post-merger galaxies.Click below for further information on:

• Starbursts & Superwinds
• Galaxy Mergers
• Elliptical galaxies
• Galaxy-cluster interactions

The Antennae is composed of stars (green in the image above), gas (blue) and dust, in a way which has been well reproduced by computer simulations. Observations at many wavelengths show that stars are forming actively within the two galaxies, triggered by the interaction, and also along the interface between the two discs. In the X-ray, large bubbles of hot gas are seen escaping from the galaxy to the south (further information is available on our merging galaxies page.
