Galaxy-galaxy collision is a phenomenon observed all over the universe. In the local universe, collisions of two massive galaxies are known to induce intense starburst activities, evolving to systems exceedingly bright in far infrared emission. In the early universe, high spatial resolution observations have found that a significant fraction of far-infrared bright sources are also colliding galaxies. Thus understanding the physical properties of the local colliding galaxy population is an important first step to improve our knowledge of the history of galaxy formation and evolution. Here I present an observational study of atomic and molecular gas emission in a sample of 10 local colliding galaxies, and present results from a comparison with numerical simulations.
