LIGOLoud signals are perfect for testing Einstein's theory of general relativity.
The previous loudest signal was #GW230814 with a signal-to-noise ratio of 42. #GW250114 has a signal-to-noise ratio of 80. This enables extremely precise tests!

Attached: 1 image Our detailed study of #GW230814 is out today https://arxiv.org/abs/2509.07348 We are able to precisely test general relativity with this loud signal. Most tests show agreement with Einstein's theory, but some… The deviations can be explained by detector noise. This is why having multiple detectors is important! #Astrodon #GWTC4 #O4IsHere

The loudest #GravitationalWave in #GWTC4 is #GW230814
Detected with only Livingston, it was still about twice as loud as GW150914!
Being loud should enable precision tests of general relativity, but with only one detector, you need to be careful with the analysis
