The star formation history of the Magellanic Clouds
The Magellanic Clouds are the closest star forming galaxies, and their star formation histories can be derived in great details from color-magnitude diagrams...
The triggering mechanisms of powerful radio galaxies: mergers and interactions.
Despite speculation that both starburst and nuclear activity in galaxies may be intimately linked via the common triggering mechanism of mergers and...
Title: SAUSAGE & TOOTHBRUSH galaxy clusters: Spectral and morphological signatures of cluster merger shocks
Clusters grow by mergers, events which release huge quantities of energy and can produce massive outward-travelling shock waves that can have an important...
The SAURON survey has revised our view of early type galaxies discovering that central disks and multiple kinematic components are common; 75% of the sample...
Tracing the Chemical Evolution of Metals in local Star-Forming Galaxies: aperture effects and abundance patterns
Nebular emission lines are a powerful diagnostic tool for tracing the chemical evolution in star-forming galaxies (SFGs) across cosmic time. Due to their...
We describe how a simple class of out of equilibrium, rotating and asymmetrical mass distributions evolve under their self-gravity to produce a quasi-planar...
Transitions from Clumpy to Smooth Galaxies over Cosmic Time
Galaxies at redshifts z~2-5 are dominated by clumpy morphologies instead of the more familiar elliptical and spiral types seen in the local Universe. The clumpy...
In the 50 years since their discovery, it has become increasingly recognised that quasars are not merely signposts to the distant Universe, but also play a key...
Truncations in stellar disks and warps in HI-layers in spiral galaxies
Disks in spiral galaxies consist of stars and gas. The stellar disks show radially an exponential surface brightness distribution (and vertically one resembling...
