Gravitational wave detection using electromagnetic modes in a resonance cavity

Gravitational wave detection using electromagnetic modes in a resonance cavity

We present a proposal for a gravitational wave detector, based on the excitation of an electromagnetic mode in a resonance cavity. The mode is excited due to the interaction between a large amplitude electromagnetic mode and a quasimonochromatic gravitational wave. The minimum metric perturbation needed for detection is estimated to the order 7 × 10 using current data on superconducting niobium...

Dual-recycled cavity-enhanced Michelson interferometer for gravitational-wave detection.

The baseline design for an Advanced Laser Interferometer Gravitational-Wave Observatory (Advanced LIGO) is a dual-recycled Michelson interferometer with cavities in each of the Michelson interferometer arms. We describe one possible length-sensing and control scheme for such a dual-recycled, cavity-enhanced Michelson interferometer. We discuss the principles of this scheme and derive the first-...

Electromagnetic radiation induced by a gravitational wave

Finding and Using Electromagnetic Counterparts of Gravitational Wave Sources

The principal goal of this whitepaper is not so much to demonstrate that gravitational wave detectors like LIGO and LISA will help answer many central questions in astronomy and astrophysics, but to make the case that they can help answer a far greater range of questions if we prepare to make the (sometimes substantial) effort to identify electromagnetic counterparts to the gravitational wave s...

Gravitational wave detection using multiscale chirplets

A generic ‘chirp’ of the form h(t) = A(t) cosφ(t) can be closely approximated by a connected set of multiscale chirplets with quadratically-evolving phase. The problem of finding the best approximation to a given signal using chirplets can be reduced to that of finding the path of minimum cost in a weighted, directed graph, and can be solved in polynomial time via dynamic programming. For a sig...
