  A great deal of evidence has been mounting over the years showing a deep
connection between acceleration, radiation, and the Unruh effect. Indeed, the
fact that the Unruh effect can be codified in the Larmor radiation emitted by
the charge was used to propose an experiment to experimentally confirm the
existence of the Unruh thermal bath. However, such connection has two puzzling
issues: (1) how the quantum Unruh effect can be codified in the classical
Larmor radiation and (2) the fundamental role played by zero-Rindler-energy
modes of the Unruh thermal bath in such a context. Here we generalize a recent
analysis made for the scalar case to the more realistic case of Maxwell
electrodynamics and settle these two puzzling issues.
