    • A consistent view of interacting dark energy from multiple CMB probes 

      Zhai, Yuejia; Giarè, William; Bruck, Carsten van de; Di Valentino, Eleonora; Mena Requejo, Olga; Nunes, Rafael da Costa (2023) [Artigo de periódico]
      We analyze a cosmological model featuring an interaction between dark energy and dark matter in light of the measurements of the Cosmic Microwave Background released by three independent experiments: the most recent data ...

    • A double take on early and interacting dark energy from JWST 

      Forconi, Matteo; Giarè, William; Mena Requejo, Olga; Ruchika, Ruchika; Di Valentino, Eleonora; Melchiorri, Alessandro; Nunes, Rafael da Costa (2024) [Artigo de periódico]
      The very first light captured by the James Webb Space Telescope (JWST) revealed a population of galaxies at very high redshifts more massive than expected in the canonical ΛCDM model of structure formation. Barring, among ...

    • The state of the dark energy equation of state circa 2023 

      Escamilla, Luis A.; Giarè, William; Di Valentino, Eleonora; Nunes, Rafael da Costa; Vagnozzi, Sunny (2024) [Artigo de periódico]
      We critically examine the state of current constraints on the dark energy (DE) equation of state (EoS) w. Our study is motivated by the observation that, while broadly consistent with the cosmological constant value w = ...
