Testing LTB Void Models Without the Cosmic Microwave Background or Large
  Scale Structure: New Constraints from Galaxy Ages
  We present new observational constraints on inhomogeneous models based on
observables independent of the CMB and large-scale structure. Using Bayesian
evidence we find very strong evidence for the homogeneous LCDM model, thus
disfavouring inhomogeneous models. Our new constraints are based on quantities
independent of the growth of perturbations and rely on cosmic clocks based on
atomic physics and on the local density of matter.
