Abstract

In a short four billion years from now the Milky Way will undergo a massive collision with our nearest neighbor the Andromeda galaxy. With over a trillion stars, Andromeda is currently moving towards us with a velocity of 110km/s. As it approaches it will deform and tear apart our galaxy until, after a few passes, gravity will eventually dominate and the two spirals will end their billion-year journey as a massive elliptical galaxy. This dramatic event is common place in our universe, with an estimated 25% off all galaxies currently undergoing a merger, these play a significant role in galactic evolution. This talk will look to present a brief history of the field of galactic evolution and dynamics from its origins to present day, including a summary of modern research techniques. This will then be discussed in the context of galaxy mergers and how we developed our current understanding about the largest collisions in the universe.
