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…
