On the phenomenology of extended Brans-Dicke Gravity
Nelson A. Lima, Pedro G. Ferreira
We introduce a designer approach for extended Brans-Dicke gravity that allows us to obtain the evolution of the scalar field by fixing the Hubble parameter to that of a CDM mode…

Constraints on hybrid metric-Palatini models from background evolution
Nelson A. Lima, Vanessa Smer-Barreto
In this work, we introduce two models of the hybrid metric-Palatini theory of gravitation. We explore their background evolution, showing explicitly that one recovers standard Gene…

Reconstructing thawing quintessence with multiple datasets
Nelson A. Lima, Andrew R. Liddle, Martin Sahlén +1
In this work we model the quintessence potential in a Taylor series expansion, up to second order, around the present-day value of the scalar field. The field is evolved in a thawi…
