Abstract

We discuss photon emission from particles decelerated by the cosmic expansion. This can be interpretated as a kind of bremsstrahlung induced by the Universe geometry. In the high momentum limit, its transition probability does not depend on detailed behavior of the expansion. This may play an important role when massless particle emission is discussed in the early Universe.
