  We examine the spectrum of bremsstrahlung photons that results from the
stopping of the initial net charge distributions in ultrarelativistic
nucleus-nucleus collisions at the CERN Large Hadron Collier (LHC). This effect
has escaped detection so far since it becomes sizable only at very low
transverse momentum and at sufficiently forward rapidity. We argue that it may
be within reach of the next-generation LHC heavy-ion detector ALICE-3 that is
currently under study, and we comment on the physics motivation for measuring
it.
