Cosmic CORALS: Timing the Universe with high-z star clusters
Elena Tomasetti, Martin Millon, Licia Verde +5
In this work, we explore the potential of anchoring the age-redshift relation across cosmic time by probing the oldest star clusters at high redshift, now observed thanks to the Ja…

The Age of the Universe with Globular Clusters III: Gaia distances and hierarchical modeling
David Valcin, Raul Jimenez, Uroš Seljak +1
This is the third article in a series aimed at computing accurate and precise ages of galactic globular clusters from their full color-magnitude diagram in order to estimate the ag…

Globular clusters as cosmic clocks: new cosmological hints from their integrated light
Elena Tomasetti, Michele Moresco, Carmela Lardo +2
We explore the reliability and robustness in measuring the age, metallicity and mass of a sample of old Milky Way globular clusters (GCs) from their integrated light, setting the s…
