Title Gravity, dark matter and its detection
Abstract I will discuss gravitational dark matter production in the Early Universe and how it spoils predictivity of most non-thermal dark matter models. I will give an example of a class of models that are free from such uncertainties known as « stronger coupling freeze-in » and discuss observational prospects for this framework.
