Cosmology with a Non-minimally Coupled Dark Matter Fluid II. Cosmological Perturbations
Samuele Silveravalle, Andrea Lapi, Francesco Benetti +1
We extend our study of a cosmological scenario in which dark matter is non-minimally coupled to gravity at the fluid level. In previous work, we showed that this interaction can dr…
Cosmology with a Non-minimally Coupled Dark Matter Fluid I. Background Evolution
Samuele Silveravalle, Andrea Lapi, Francesco Benetti +1
We explore a cosmological model in which dark matter is non-minimally coupled to gravity at the fluid level. While typically subdominant compared to Standard Model forces, such cou…
A Relativistic Tensorial Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +5
In a series of recent papers it was shown that several aspects of Dark Matter (DM) phenomenology, such as the velocity profiles of individual dwarfs and spiral galaxies, the scalin…
Ultra-compact Objects of Non-minimally Coupled Dark Matter
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +1
In the framework of a collisionless dark matter fluid which is non-minimally coupled to gravity, we investigate the existence and properties of static, spherically symmetric soluti…
