- 1Ultra-precise coatings to power next-generation gravitational wave detectors●Ultra-precise coatings help power the next generation of gravitational wave detectors
New ultra-precise mirror coatings are being developed to improve the sensitivity of gravitational wave detectors such as LIGO, allowing them to detect fainter cosmic events like black hole and neutron star mergers. Reducing thermal noise in these coatings is a key challenge for upcoming detector upgrades, and researchers report progress in materials that could extend the reach of gravitational wave astronomy.
