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…
Dark energy driven by an oscillating generalised axion-like quintessence field
Mariam Bouhmadi-López, Carlos G. Boiza
Generalised axion-like scalar fields provide a well-motivated framework for describing the late-time acceleration of the Universe. As the field evolves, it rolls down its potential…
Modified Teleparallel Gravity, DESI BAO and the Tension
Mariam Bouhmadi-López, Carlos G. Boiza, Maria Petronikolou +1
We investigate whether late-time modifications of gravity in the teleparallel framework can impact the current tension in the Hubble constant , focusing on cosmology as…
Addressing and tensions within cosmology
Carlos G. Boiza, Maria Petronikolou, Mariam Bouhmadi-López +1
We investigate the viability of gravity as an alternative framework to address the and tensions in cosmology. Focusing on three representative models, we…
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.…
