Testing the consistency between cosmological measurements of distance and age
We present a model independent method to test the consistency between
cosmological measurements of distance and age, assuming the distance duality
relation. We use type Ia supernovae, baryon acoustic oscillations, and
observational Hubble data, to reconstruct the luminosity distance D_L(z), the
angle averaged distance D_V(z) and the Hubble rate H(z), using Gaussian
processes regression technique. We obtain estimate of the distance duality
relation in the redshift range 0.1<z<0.73 and we find no evidence for
inconsistency between the data sets used.Comment: 5 pages, 1 pdf figure, minor revision, accepted for publication in
