Numerical CLONES of the local Universe: kesako and why?
Abstract
As a field without ground truth, cosmology relies on cosmological simulations for data interpretation. This talk will present a peculiar type of cosmological simulations constrained to reproduce our local Universe within about 500 Mpc. These simulations, because they mimic our local cosmic environment, include synthetic replica of our favorite close-by objects like the Virgo cluster of galaxies and the Milky Way. As such, they are excellent tools for analyzing and understanding local observational data without environmental biases. After introducing CLONES, which are a set of constrained simulations valid down to the galaxy cluster scale, this talk will give a few example uses of these simulations.
