Abstract:
During the recent years, decaying dark matter models have received renewed interest as proposed solutions to the current cosmological tensions. In this talk, I will journey through the history of invisibly decaying dark matter models, culminating with our recent work on decaying warm dark matter. Decaying warm dark matter is a very flexible and often well-motivated model that interpolates between several other dark matter models. Among other things, I will discuss its fascinating phenomenology, its numerical implementation, and present results from a comprehensive MCMC analysis, evaluating the consequence of the model on the Hubble and 𝜎8 tensions. Lastly, I emphasise the power of agnosticism with respect to the underlying particle physics realisation and discuss applications neutrino decays, majorons, sterile neutrinos and more; all of which can be quantitatively described as decaying warm dark matter.
