Query: Accelerated-Cherenkov radiation and signatures of radiation reaction   In this manuscript we examine an accelerated charged particle moving through
an optical medium, and explore the emission of accelerated-Cherenkov radiation.
The particle's reaction to acceleration creates a low-frequency spectral cutoff
in the Cherenkov emission that has a sharp resonance at the superluminal
threshold. Moreover, the effect of recoil on the radiation is incorporated
kinematically through the use of an Unruh-DeWitt detector by setting an energy
gap, i.e., the change in electron energy, to the recoil energy of the emitted
photon. The simultaneous presence of recoil and acceleration conspire to
produce a localized resonance peak in the emission. These theoretical
considerations could be used to construct high precision tests of radiation
reaction using Cherenkov emission under acceleration.
