  Classical electromagnetic radiation from moving point charges is
foundational, but the thermal dynamics responsible for classical acceleration
temperature are poorly understood. We investigate the thermal properties of
classical electromagnetic radiation in the context of the correspondence
between accelerated electrons and moving mirrors, focusing on three
trajectories with asymptotically infinite (Davies-Fulling), asymptotically zero
(Walker-Davies), and eternally uniform acceleration. The latter two are argued
not to be thermal, while the former is found to emit thermal photons with a
temperature that depends on the electron's speed. Thermal radiation from the
mirror reveals a zero-jerk condition.
