Mass Distribution in the Core

    The core of the satellite galaxy is close to one hundred times denser than that of the primary galaxy. As a result the satellite core remains essentially unaltered during the simulation but the primary's core gets significantly distorted. Below are links to three movies which demonstrate this. The movies are quite large (3-4 MEG)  so please have patience.
