"Dark matter is captured by the Sun and can yield a smoking gun signature when it annihilates to dark photons that exit the Sun"
Feng, Smolinsky, and Tanedo, Phys. Rev. D 93, 115036 (2016)
"We have demonstrated that gamma-ray measurements of the Sun are exceptionally sensitive to the dark matter scattering cross section"
HAWK Collaboration, Phys. Rev. D 98, 123012 (2018)
"We find the solar gamma ray constraints to be strong and complementary with other bounds on dark photon models, such as those arising from supernova and beam dump experiments"
Bell, Dent, and Sanderson, Phys. Rev. D 104, 023024 (2021)
