A new path to constrain the expansion history of the Universe in future spectroscopic galaxy surveys
Elena Tomasetti, Michele Moresco, Nicola Borghi +6
The current tension between early- and late-Universe measurements of the Hubble constant (), along with the still elusive nature of dark matter and dark energy, calls for mode…
Standard Sirens in 2040s: Probing the Cosmic Expansion History with Gravitational Waves and Spectroscopic Galaxy Surveys
Nicola Borghi, Michele Moresco, Richard I. Anderson +11
Gravitational waves (GWs) from compact binary coalescences have matured into a robust cosmological probe, providing self-calibrated luminosity distance measurements independent of…
Cosmic chronometers with galaxy clusters: a new avenue for multi-probe cosmology
E. Tomasetti, M. Moresco, G. Granata +9
We provide a new measurement of the expansion history of the Universe at with the cosmic chronometers (CC) method, exploiting the high-quality spectroscopic VLT/MUSE data…
The oldest Milky Way stars: New constraints on the age of the Universe and the Hubble constant
Elena Tomasetti, Cristina Chiappini, Samir Nepal +6
We exploit the most robust, old, and cosmology-independent age estimates of individual stars from Gaia DR3 to place a lower bound on the age of the Universe, . These constrain…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
