Title:
Some modeling clay for cosmology

Speaker:
Mark Kamionkowski

Abstract:
We have a pretty good cosmological model: A few simple ansatzes and a handful of parameters go a long way in terms of explaining a broad array of observations and complicated data. Still, there are possibly some gaps and plenty of questions. These include the Hubble and S8 tension, but also other, less trumpeted, possible inconsistencies, including a recently noted excess of cosmic optical photons. There are then new directions in the modeling phase space that may be intriguing: for example, I have been interested in understanding how well we can determine whether baryons trace matter. I will discuss recent work related to all of these subjects.
