Cosmic Bose dark matter

Abstract

Cold and hot dark matter (CDM, HDM) imprint distinctive effects on the cosmological observables, naturally, they are often thought to be made of different kinds of particles. However, we point out that CDM and HDM could share a common origin, a Bose-Einstein condensate emerging with two components. In this framework, the mass and temperature constraints on HDM contain fundamental information of CDM, but also, the critical temperature of condensation shall be larger than the HDM temperature. We discuss two scenarios: a gas made of bosons and a gas made of boson-antiboson pairs. We use some cosmological data surveys to test the idea and constrain the bosonic DM parameters, including a forecast for the Planck mission. We find that the bosonic DM picture is consistent with data in the first scenario, although, the second one might be increasingly interesting for future data surveys.
