"On the application of astrophysical signals to gravitational-wave detector calibration" — an artistic interpretation of our latest science with #GW240925 and #GW250207 by @ASleepyWanderer
For the first time, we have used the signals from binary black holes to check the precise calibration of our detectors
These #GW240925 and #GW250207 infographics have been translated into a range of languages by our LIGO Virgo KAGRA Collaboration members

Not accounting for calibration errors can give incorrect results
#GW250207 allows for precise tests of the ringdown of the final black hole. The results agree with predictions when accounting for calibration uncertainty, but neglecting them gives biased results. You might think you have found a deviation from general relativity, when in fact, it is just the calibration of the data!
Astrophysical calibration enables us to analyze data we couldn't otherwise
With the inclusion of LIGO Hanford data, #GW250207 is the second loudest ever
Using data from all three detectors makes a big difference to localizing the source
