Listening for dark photon radio signals from the galactic center
- Abstract:
-
Dark photon dark matter that has a kinetic mixing with the Standard Model photon can resonantly convert in environments where its mass 𝑚𝐴′ coincides with the plasma frequency. We show that such conversion in neutron stars or accreting white dwarfs in the Galactic Center can lead to detectable radio signals. Depending on the dark matter spatial distribution, future radio telescopes could be sensitive to values of the kinetic mixing parameter that exceed current constraints by orders of magnitude for 𝑚𝐴′ ∈(6×10−6,7×10−4) eV.
