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…
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…
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…
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…
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…
