COS4: Modelling Dark Energy and Modified Gravity

Session Organisers: 

Richard Battye (University of Manchester), Jochen Weller (LMU, Germany)


The discovery of cosmic acceleration has been recently recognised by the award of the Nobel prize for physics. However it is origins are still a mystery: there are many models to explain this phenomenon, but none are compelling. It could be a dark energy component, or result from a modification to gravity at long distances. The aim of this session is to explore both individual models and phenomological approaches to describing cosmic acceleration. It will complement the sessions on future photometric and spectroscopic observations which are designed, amongst other things, to probe these models.
