Time to Sparkler. Accurate ages of lensed globular clusters at with JWST photometry
Elena Tomasetti, Michele Moresco, Carmela Lardo +5
Determining reliable ages for old stellar objects at different redshifts offers a powerful means to constrain cosmology without relying on a specific cosmological model: this is kn…

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…
