New Optical Cavity Detectors Open the Milli-Hz Gravitational-Wave Frontier
A New Path to the Mid-Band Gravitational-Wave Frontier For decades, gravitational waves have revealed themselves across a broad spectrum—from the high frequencies detected by LIGO and Virgo on Earth to the ultra-low frequencies explored by pulsar timing arrays. Yet a crucial gap remained in the middle: the milli-Hertz band, roughly from 10^-5 to 1 Hz,…

New Approach to Gravitational Wave Detection Opens the Milli-Hz Frontier
A New Frontier in Gravitational Wave Detection Researchers from the Universities of Birmingham and Sussex have unveiled a promising new approach to detecting gravitational waves in the milli-Hertz range. This mid-band, or milli-Hz, frequency region has long eluded observation by existing instruments, leaving a gap between high-frequency ground-based detectors and ultra-low-frequency pulsar timing arrays. The…

Milli-Hertz frontier: Compact detectors unlock gravitational wave ‘mid-band’
The new mid-band detector idea A collaboration between the Universities of Birmingham and Sussex has unveiled a compact, ground-based detector concept that targets the elusive milli-Hertz gravitational wave band. By combining advanced optical cavity technology with atomic clock references, the project aims to fill the long-standing gap in the gravitational wave spectrum between terrestrial interferometers…
