Synopsis

It has been long established that galaxies can be divided into those that star-forming spiral discs and those that are spheroids that have stopped forming stars long ago.  Despite decades of attempts to fit galaxy evolution into a cookie-cutter model, it is becoming evident that galaxies grow and evolve from one class to the other through numerous evolutionary pathways.  From passive evolution to the dramatic influence of black hole activity driving gaseous outflows, to the influence of the vast cosmic web, I will review the different drivers of galaxy evolution in light of the latest observational and theoretical discoveries.  Drawing upon my own research, I will discuss issues of correlation and causation, and highlight evidence that points to multiple evolutionary pathways along which galaxies both grow and fade.
