  Radiation from accelerating mirrors in a Minkowski spacetime provides
insights into the nature of horizons, black holes, and entanglement entropy. We
introduce new, simple, symmetric and analytic moving mirror solutions and study
their particle, energy, and entropy production. This includes an asymptotically
static case with finite emission that is the black hole analog of complete
evaporation. The total energy, total entropy, total particles, and spectrum are
the same on both sides of the mirror. We also study its asymptotically
inertial, drifting analog (which gives a black hole remnant) to explore
differences in finite and infinite production.
