coherent oscillator injection and recovery

Coherent oscillators&mdash;astronomical sources that pulse or oscillate in a phase-stable way over long timescales&mdash;have been useful astrophysical tools. For two examples: Stably pulsing pulsars were used to discover gravitational radiation (and are being used to find the stochastic background). Delta-scuti star asteroseismic modes were used to find orbital companions. This led undergrad Nana…
