Inferring the Age of the Universe with Globular Clusters

Valcin, David, Bernal, José Luis, Jimenez, Raul et al.

Understand

We present an estimate of the absolute age of 68 galactic globular clusters obtained by exploiting the distribution of stars in the full color-magnitude diagram.

In particular, we jointly estimate the absolute age, distance, reddening, metallicity ([Fe/H]) and [$\alpha$/Fe] of each cluster, imposing priors motivated by independent observations; we also estimate possible systematics from stellar modeling.
Our derived distances for the globular cluster sample are in agreement with those obtained from GAIA using main-sequence dwarf stars (where available), and the inferred ages are in good agreement with those previously published.
The novelty of our approach is that, with the adopted priors, we are able to estimate robustly these parameters from the globular cluster color-magnitude diagram.
