Reaching the Metallicity Floor at : Lensed Star Clusters at Cosmic Dawn and Cosmic Noon
Raul Jimenez, Elena Tomasetti, Carmela Lardo +1
Origins of globular clusters (GCs) are linked to the assembly of their host galaxies. We analyze star-cluster populations in two strongly lensed systems that bracket Cosmic Dawn an…

Chemo-dynamical reconstruction of Milky Way globular cluster progenitors: Age-metallicity relations and the universality of multiple stellar populations
Carmela Lardo, David Valcin, Raul Jimenez
Globular clusters encode the hierarchical assembly history of the Milky Way and the physics of multiple stellar populations. Using homogeneous stellar parameters for 69 Galactic gl…

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…
