Cosmography with DESI-DR1 Cosmic Chronometers: Direct H(z) measurements from Luminous Red Galaxy ages
Carlos A. Álvarez, Marcos M. Cueli, Balakrishna S. Haridasu +6
Providing robust redshift estimates for almost 3 million luminous red galaxies (LRGs), the Dark Energy Spectroscopic Instrument (DESI) offers a unique opportunity to test the expan…

Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Ãlvarez, Marcos M. Cueli, Alessandro Bressan +5
Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of…

StAGE: Stellar Archaeology-driven Galaxy Evolution
Michele Bosi, Andrea Lapi, Lumen Boco +10
We build a semi-empirical framework of galaxy evolution (dubbed StAGE) firmly grounded on stellar archaeology. The latter provides data-driven prescriptions that, on a population s…
