Testing the distance duality relation with present and future data

Abstract:

The assumptions that light propagates along null geodesics of the spacetime metric and the number of photons is conserved along the light path lead to the distance duality relation (DDR), η=D L(z)(1+z) -2/D A(z)=1, with D L(z) and D A(z) the luminosity and angular diameter distances to a source at redshift z. In order to test the DDR, we follow the usual strategy compar...
