The angular size-redshift relation has always looked like an interesting way to test cosmological ideas since the L-CDM model predicts this apparently strange behaviour for redshifts higher than around z=1.6, but sadly is plagued with technical difficulties arisin mainly from these very high redshifts. I recently read something (Gurvits 1998) but it's quite dated and it was rather inconclusive with several observations outside the values predicted by the L-CDM model. Perhaps someone knows about more recent observations the shed light about this issue. Thanks.(adsbygoogle = window.adsbygoogle || []).push({});
