The Atacama Cosmology Telescope: DR6 constraints on extended cosmological models

Journal of Cosmology and Astroparticle Physics
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test foundational assumptions of the standard cosmological model, ΛCDM, and set ...

DILATON COSMOLOGY

Modern Physics Letters A, 2010
In Brans–Dicke gravitational theory, an analytical accelerating expansion solution of the Universe is found at the dilaton dominated epoch. Both Einstein frame (EF) and Jordan frame (JF) are applied. We consider the form of exponential potential of dilaton field in EF while we consider the power law potential in JF.
