Three-form dark energy: constraints and multi-probe comparison with CDM
Mariam Bouhmadi-López, Hsu-Wen Chiang, Carlos G. Boiza +3
Three-form fields provide a theoretically well-motivated framework for dark energy, arising in higher-dimensional theories and exhibiting a rich cosmological phenomenology. We inve…
Observational constraints on 3-forms dark energy
Mariam Bouhmadi-López, Hsu-Wen Chiang, Carlos G. Boiza +1
3-forms are natural candidates for describing the late-time accelerated expansion of the Universe, as they can inherently reproduce a positive cosmological constant when lacking an…
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.…
Observational constraints on generalised axion-like potentials for the late Universe
Hsu-Wen Chiang, Carlos G. Boiza, Mariam Bouhmadi-López
Axions have emerged as compelling candidates for describing the dark sector of the Universe. In this work, we explore quintessence models inspired by axion-like potentials as a dyn…
