Summary

Story summary

Researchers from the United Kingdom propose a tabletop gravitational wave detector using optical resonator technology to target midband frequencies from 0.001 to 1 Hz.
The design uses two rigid optical cavities to measure phase shifts in laser light caused by gravitational waves.
The compact, on-table design reduces noise and enables immediate operation, while LILA, a lunar-based detector, would capture low-frequency waves.

History

Historical Context

The detection of gravitational waves by the LIGO collaboration in 2015 confirmed Einstein's 1916 prediction, marking a significant milestone in astrophysics. Initial detection efforts began in the late 1960s, leading to the development of advanced interferometric techniques. The proposed UK tabletop detector aims to enhance detection capabilities, complementing existing projects like Virgo, which focuses on low-frequency gravitational waves.
