We consider the astrophysical bounds on a new form of dark matter, the so called Gravity-mediated Dark Matter. In this scenario, dark matter communicates with us through a mediator sector composed of gravitational resonances, namely a new scalar (radion) and a massive spin-two resonance (massive graviton). We consider specific models motivated by natural electroweak symmetry breaking or weak-scale dark matter in the context of models in warped extra-dimensions and their composite duals. The main Dark Matter annihilation mechanism is due to the interactions of KK gravitons to gauge bosons that propagate in bulk. We impose the bounds on monochromatic or continuum photons from Fermi-LAT and HESS. We also explore scenarios in which the Fermi gamma-ray line could be a manifestation of Gravity-mediated Dark Matter.

Light PIDM in Warped Extra Dimensions
A UV-Dark-IR brane construction in warped 5D space allows light (MeV-TeV) purely gravitational dark matter to freeze in with TeV-scale reheating temperatures.

Baryon-dark matter coincidence in Randall-Sundrum Model
Graviton- and radion-mediated freeze-in in a Randall-Sundrum model can match the observed dark matter relic abundance, and TeV-scale resonant leptogenesis through the same portals can match the observed baryon asymmet...

Signatures of gravity-mediated dark matter interaction in theories with large extra dimensions
In ADD models with n large extra dimensions, gravity-mediated DM-nucleon interactions scale as m_p m_χ M_*^{-4} and resonant annihilation as ⟨σv⟩ ~ m_χ^n M_*^{-n-2}, yielding bounds on {m_χ, M_*} from Xe direct detect...
