A Spectrum of Cosmological Rips and Their Observational Signatures
Mikel Artola, Ruth Lazkoz, Vincenzo Salzano
We present a unified dark energy framework capable of generating a continuous spectrum of cosmological ``rip'' scenarios -- including the Big Rip, Grand Rip, Mild Rip, Little Rip,…
Geometric acceleration in theories
Mikel Artola, Ismael Ayuso, Ruth Lazkoz +2
The framework of gravity enables the depiction of an effective dark energy fluid that emerges from geometry itself, thus leading to modifications in the cosmological pheno…
Is Chevallier-Polarski-Linder dark energy a mirage?
Mikel Artola, Ismael Ayuso, Ruth Lazkoz +1
Recent observations from the Dark Energy Spectroscopic Instrument (DESI) raise doubts about the standard cosmological model, CDM, suggesting a preference for an inherently dynam…
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.…
Probing Interacting Dark Sector with the next generation of gravitational-wave detectors
Matteo Califano, Ivan De Martino, Ruth Lazkoz
We have probed the capability of third-generation Gravitational Waves (GW) interferometers, such as the Einstein Telescope and Cosmic Explorer, to constrain a cosmological model wi…
Characterization of wormhole space-times supported by a covariant action-dependent Lagrangian theory
Ismael Ayuso, Ruth Lazkoz
In this work, we undertake an analysis of new wormhole solutions within an action-dependent Lagrangian framework. These geometries can be traversable and supported by a positive en…
