Speaker
Description
The accuracy of the interpretation of the current generation of late-time cosmology probes is greatly limited by the theorists' ability to predict the response of baryons. This will only get more difficult in the coming years with the upcoming surveys (DESI-BGS, Euclid, LSST, 4-most, Simons) mapping our sky with unprecedented precision.
In this talk, I will discuss some of the efforts towards this challenge on the simulation side. I will, in particular, focus on the new generation of simulations, the FLAMINGO suite, designed to be virtual twins of the Stage IV cosmology surveys. This suite includes the largest simulation ever run to z=0 and exploits a state-of-the-art baryon physics model calibrated to the relevant data. Variations in the physics, trained via machine learning techniques, allow us to encompass the uncertainty in the modeling. Outputs in observer space, such as X-ray, stellar light and SZ lightcones are produced and are used to validate the simulations. This talk will have a special focus on SZ-probes and data producs extracted from the simulations. This talk is also a invitation to collaborate and make use of this data for your research.
