Colloquium by Baojiu Li (Durham University )

Shedding Light on the Darkness


In the coming decade, an array of galaxy and cluster surveys will significantly improve observational tests of cosmological models to explain the accelerated cosmic expansion. In this talk, I will review some recent progresses in this area. In particular, I will discuss studies, based on cosmological simulations, on modified gravity models, how future observations can help to test these models, and some practical limitations that need to be overcome before accurate constraints can be obtained.
