Testing BEC Dark Matter with Gravitational Waves
Abstract
We study the phenomenology associated to nonminimally coupled dark matter. In particular, we consider the model where the nonminimal coupling arises from the formation of relativistic BoseEinstein condensates in high density regions of dark matter [1]. This nonminimal 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 nonminimal coupling.
