| Summary:
We study inelastic dark matter produced via freeze-in through a light
mediator with a mass splitting below the electron-positron threshold. In this
regime, the heavier dark matter state is naturally long-lived compared to the
age of the Universe and decays to the lighter state in association with
photons. Given a light mediator, the dark matter abundance is directly related
to the decay rate of the heavier dark matter. We show that observations of
photons from the galactic center can effectively probe inelastic dark matter
freeze-in with mediators at the $100~rm MeV$ scale and dark matter at the $rm
GeV$ scale.
