Energy-Momentum portal to dark matter and emergent gravity
  We propose a new scenario where dark matter belongs to a secluded sector
coupled to the Standard Model through energy--momentum tensors. Our model is
motivated by constructions where gravity {\it emerges} from a hidden sector,
the graviton being identified by the kinetic term of the fields in the secluded
sector. Supposing that the lighter particle of the secluded sector is the dark
component of the Universe, we show that we can produce it in a sufficiently
large amount despite the suppressed couplings of the theory, thanks to large
temperatures of the thermal bath in the early stage of the Universe.
