You are all invited to participate in the BiCoQ seminar “How transparent is the Universe?“
Speaker: Professor Tom Theuns (Durham University)
Abstract: Numeral simulations have become instrumental in our interpretation of astronomical observations.
State-of-the-art cosmological simulations now routinely include complex non-linear physical processes, and
we may struggle to grasp the key ingredients that are needed to reproduce observations.
I will present two examples of how taking a step back from the details may help us focus in
on the essentials. In particular, I will show how simple models inspired by simulations predict
successfully the slope of the galaxy stellar mass function and that of the column density distribution
function of lines in the Lyman-alpha forest.
