Brans–Dicke cosmology with a Λ-term: a possible solution to ΛCDM tensions
JS Peracaula, A Gómez-Valent… - … and Quantum Gravity, 2020 - iopscience.iop.org
We present a full-fledged analysis of Brans–Dicke cosmology with a cosmological constant
and cold dark matter (BD-ΛCDM for short). We extend the scenarios where the current
cosmological value of the BD-field is restricted by the local astrophysical domain to
scenarios where that value is fixed only by the cosmological observations, which should be
more natural in view of the possible existence of local screening mechanism. Our analysis
includes both the background and perturbations equations in different gauges. We find that …
