We study the phenomenology associated to non-minimally coupled dark matter. In particular, we consider the model where the non-minimal coupling arises from the formation of relativistic Bose-Einstein condensates in high density regions of dark matter [1]. This non-minimal coupling is of Horndeski type and leads to a local modification of the speed of gravity with respect to the speed of light. Therefore we can constrain the model by using the joint detection of GW170817 and GRB170817A. We show that the constraints obtained in this way are quite tight, if the dark matter field oscillates freely, whereas they are substantially weakened, if the oscillations are damped by the non-minimal coupling.

  1. Nonminimally coupled Dark Matter in Clusters of Galaxies: a fully comprehensive analysis

    astro-ph.CO 2024-12 conditional novelty 6.0 of 10

    A disformal dark matter-gravity coupling length is constrained to be very small by CLASH cluster lensing, consistent with general relativity.

  2. Exploring Non-minimal coupling using ultra-diffuse galaxies

    astro-ph.CO 2026-02 conditional novelty 5.0 of 10

    A Bayesian Jeans analysis of three ultra-diffuse galaxies finds no preference for a non-minimal dark-matter-gravity coupling and yields weak upper limits on its length scale.
