Cosmographic analysis of sign-switching dark energy
Mariam Bouhmadi-López, Beñat Ibarra-Uriondo
Inspired by the well-studied CDM model, we propose and investigate a class of dynamical dark energy models that evolve from a negative cosmological constant, transitioni…
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…
Dark energy with a shift-symmetric scalar field: obstacles, loophole hunting and dead ends
Teodor Borislavov Vasilev, Mariam Bouhmadi-López, Prado Martín-Moruno
We discuss the possibility of a scalar field being the fundamental description of dark energy. We focus on shift-symmetric scalar-tensor theories since this symmetry potentially av…
