Extragalactic Astronomy and Cosmology at Edinburgh

Over the next five years, a team of eight astronomers at the University of Edinburgh’s Institute for Astronomy will mine data from the world’s most powerful new telescopes and computer simulations to map how galaxies, black holes, and the universe itself have evolved since the Big Bang. This matters because the current picture of cosmic history has major gaps. Astronomers do not fully understand how the first galaxies formed, how supermassive black holes grew inside them, or why the universe’s expansion is accelerating. The Edinburgh group has helped design and build several of the key surveys and simulations that will now deliver their first major datasets—including deep-sky maps and large-scale structure simulations—so the timing of this grant is critical for turning raw data into physical understanding. This is fundamental science. It will not produce a new battery or a faster computer chip. But the same kind of curiosity-driven research that once asked “what are those fuzzy patches in the sky?” later gave us the physics behind GPS satellites and the discovery of dark energy. If this programme succeeds, it will refine our understanding of how structure emerged from the early universe—knowledge that, historically, has reshaped everything from cosmology to the technologies that rely on precise models of space and time.
