Galaxy evolution is a messy business, where more massive systems are built up by collisions between smaller galaxies. We can study this growth in great detail within our own Galaxy, as we can see smaller galaxies falling in towards us, and getting completely torn apart. But, in a few billion years, the Milky Way won’t be the one doing the shredding anymore, as it will collide with our more massive neighbour, Andromeda. In this talk, I’ll show you how both these galaxies have been growing for the past 14 billion years, and what will happen when they finally merge together.
The lecture will be held in lecture theatre D in building 26 at the University of Surrey. A campus map can be found here: https://www.surrey.ac.uk/sites/default/files/campus-map-2017.pdf
