Supercomputer Simulations of Merging Galaxies:
Mergers, Starbursts, and Galaxy Evolution
Observations of Colliding Galaxies:
Snapshots in Time
Problem: Galaxy collisions take hundreds
of millions or even billions of years to occur -- we
can't watch a collision happen.
When we observe interacting galaxies we see fragmented, differing pieces
of a larger evolutionary process.

We want to understand how these "snapshots" relate, and explore
galaxy collisions in an evolutionary context.
- What happens when galaxies collide?
- How do interactions trigger
- Can mergers make elliptical
- What about smaller accretion
