Almost one hundred years ago, astronomer Edwin Hubble revolutionised our understanding of the Universe and our place in it when he discovered that it extends beyond the Milky Way. Since then, astronomers have identified millions of galaxies beyond our own, and developed sophisticated techniques to measure their distances and motions. In this talk, I will show how astronomers map the Universe using large surveys of galaxies, and how "cosmic maps" are an essential tool in Cosmology, allowing us to understand the physical nature and history of the Universe. Presented on 15 April 2016.
