Physics Colloquium: Licia Verde

Speaker: Licia Verde, Catalan Institution for Research and Advanced Studies and Institute of Cosmological Sciences, University of Barcelona
Title: Unconscious Bias…in Cosmology
Abstract: The standard cosmological model has been established and its parameters are now measured with unprecedented precision. However, there is a big difference between modelling and understanding. The next decade will see the era of large surveys; a large coordinated effort of the scientific community in the field is on-going to map the cosmos producing an exponentially growing amount of data. This will shrink the statistical errors.
But precision is not enough: accuracy is also crucial. Accuracy is very difficult to assess, and residual biases may remain. Systematic effects may be in the data but may also be in the model used in their interpretation. I will present a small selection of examples where I explore approaches to help the transition from precision to accurate cosmology. This selection is not meant to be exhaustive or representative, it just covers some of the problems I have been working on recently.
