# Fuzzy Cosmology at ITP2022

As I usually do when I give a talk (which hasn’t been for a while) I’ve uploaded the slides for the presentation I gave at the Irish Theoretical Physics meeting at DIAS this morning. The title of the talk was *Fuzzy Cosmology* and the abstract reads:

I discuss some applications of the Schrodinger-Poisson wave-mechanical approach to

cosmological structure formation. The most obvious use of this formalism is to “fuzzy” dark matter,

i.e. dark matter consisting of extremely light particles whose effective de Broglie wavelength is

sufficiently large to be astrophysically relevant, but it can be used to model more general scenarios

and has a number of advantages over standard methods based on Eulerian perturbation theory. I

illustrate the formalism with some calculations for cosmic voids and discuss its application to the

cosmological reconstruction problem(s).

I think it went reasonably well despite there being a hitch at the start because the touchpad on my laptop stopped working. Fortunately I was able to produce an emergency mouse. Anyway, here is a picture of me taken during the talk to prove I was there..
