Sensitivity of calibration-free DESI DR2 BAO--supernova constraints to a distance-duality tilt
Stéphane Fay, Mikel Artola, Leandros Perivolaropoulos
Recent measurements from DESI baryon acoustic oscillations (BAO) have reported a moderate preference for dynamical dark energy, challenging the CDM paradigm. Nonetheless, such a…
Generalizing the CPL Parametrization through Dark Sector Interaction
Mikel Artola, Ruth Lazkoz, Vincenzo Salzano
We investigate a hierarchy of interacting dark energy (IDE) models featuring a non-gravitational coupling between dark matter and dark energy. Specifically, we examine scenarios wh…
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…
Gravitational and electromagnetic Cherenkov radiation constraints in modified dispersion relations
Mikel Artola, José A. R. Cembranos, Prado Martín-Moruno
Motivated by different approaches to quantum gravity, one could consider that Lorentz invariance is not an exact symmetry of nature at all energy scales. Following this spirit, mod…
