Nonlocal Gravity, Restricted CPL Dynamics and DESI Constraints
Luca Amendola, Ismael Ayuso, Amlan Chakraborty +2
Nonlocal modifications of gravity provide a theoretically motivated framework in which cosmic acceleration can emerge dynamically without introducing a fundamental cosmological con…
Degenerate and connection-dependent cosmological sectors in f(Q,C) gravity
Ismael Ayuso
We investigate cosmological solutions in gravity formulated within symmetric teleparallel geometry, where gravitation is described by the nonmetricity scalar and the b…
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…
Insights in cosmology: the relevance of the connection
Ismael Ayuso, Mariam Bouhmadi-López, Che-Yu Chen +3
We explore the role of the affine connection in gravity, a modified theory where gravity is governed by non-metricity within the symmetric teleparallel framework. Although t…
