as you all know, current cosmological N-body simulations (like the Millenium run) are based on the Newtonian limit. Gravitational fields are supposed to be rather weak and therefore the force between dark matter particles reduces to Newtonian gravity. Other relativistic effects are neglected. The cosmological background expands independently of the non-linear processes inside the simulation box. In connection with backreaction studies it might be very useful to have fully-relativistic cosmological N-body simulations. I know that it is extremely difficult to simulate only two merging black holes with all relativistic effects so N-body codes might be completely out of reach. But still, I am interested in this topic. I am not aware of any work on this field.

Can anybody recommend me any article, paper, book or whatsoever? Any source of information is welcome.

Thank you very much in advance!

Best wishes,

Matt
