Astro & GW Colloquium

Galaxies, Black Holes, and Citizen Science: The Next Decade

Speaker: Dr Brooke Simmons (Lancaster University)
Date: Wednesday 6 February 2019
Time: 14:00
Venue: Queens Buildings N/3.28

Galaxy growth and evolution may be broadly categorized as either driven by galaxy-galaxy collisions/mergers, or merger-free. Merger-free processes are important to galaxy evolution, yet many fundamental open questions remain: how does galaxy star formation halt without a disruptive merger? How do central 'supermassive' black holes grow in galaxies without mergers? How do these questions impact each other? This talk will review the field of merger-free galaxy and black hole evolution and discuss the relative importance of mergers and completely calm, 'secular' evolution on galaxy and black hole growth, including new evidence from recent cosmological simulations and a new Hubble Space Telescope survey designed to answer these questions. These results are made possible by the contributions of hundreds of thousands of members of the public to Galaxy Zoo; I will discuss the future of citizen science endeavours in the context of the next generation of telescopes and surveys.
