KAGRA
1 reportKAGRA is a physics detector designed to separate rare particles or physical signals from background noise and instrumental effects. The project is evaluated through systematic uncertainty, signal threshold, and event reconstruction, separating design goals from capabilities demonstrated in operation.
The page treats source parameter estimation and multi-observatory confirmation, with separate attention to interferometer sensitivity as distinct parts of KAGRA. The account follows control samples as the direct record and cross-checks between analysis teams as the broader comparison for interferometer sensitivity; confidence is limited by the fact that rare-event searches remain sensitive to backgrounds and threshold choices.

Gravitational Wave Data Reveals Black Hole Event Horizon Properties
Researchers have extracted direct physical parameters from a black hole event horizon using an unusually strong gravitational wave signal, providing new experimental access to a region previously studied only through theory
