Description
The standard model of cosmology, LCDM, suffers from both theoretical and observational problems that motivate alternative theories of dark energy. One such class of theories are interacting dark energy models. In my talk, I will give an overview of the problems with LCDM and discuss the interacting vacuum scenario, in which the time-varying vacuum energy is allowed to interact with dark matter. I will explain how this interaction can be reconstructed from and constrained by observational data and present some preliminary results.
