Dr Steve Barrett – The ABC of Galaxy Evolution
13 Sep at 9:30 am – 9:30 pm
What are the three factors (the ABC) that determine how galaxies form and how they grow? A = Accretion – Galaxies were formed by matter accreting; B = Black Holes – Supermassive black holes are at the centres of galaxies; C = Collisions – Galaxies grow by colliding and merging.
