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…
