Query: Boson stars, primary photons and phase transitions   We analyse the possibility that the dark matter candidate is from the
approximate scale symmetry theory of the hidden scalar sector. The study
includes the warm dark matter scenario and the Bose-Einstein condensation which
may lead to massive dark scalar boson stars giving rise to direct detection
through observation of the primary (direct) photons.
