Title:
Cosmicflows, Bayesian inference, constrained simulations and the Local Universe
Abstract:
The association of ‘Near Field’ and ‘Cosmology’ rests on the implicit Copernican assumption that the near field constitutes a typical patch of the universe. A key question that needs to be addressed is how typical the near field is, and thereby how relevant it is to cosmology at large. Constrained simulations embody Near Field Cosmology in the realm of cosmological simulations and are used here to shed light on the problem.
