Abstract:
A third-generation GW detector such as ET will be able to measure 
binary neutron star coalescences up to cosmological distances. This will 
allow us to explore the dark-energy sector of generic modifications of 
General Relativity. In the dark energy sector a well-know observable is 
the equation of state of dark energy. However, its determination with ET 
will probably not be significantly better than what can already be 
obtained with electromagnetic observations (CMB, BAO, Supernovae). We 
will discuss recent work that shows that there is another way of testing 
the dark-energy sector, through modified GW propagation.
