Oo! Interesting #GravitationalWave candidate #S251112cm potentially from a *subsolar* mass source

If real, the source probably has chirp mass ~0.1–0.87 solar masses

False alarm rate 1 in 6.2 yr

Last Sunday was the 10th anniversary of our first #GravitationalWave detection!

Join us for a thread of celebratory cakes enjoyed by members of our collaboration

First, a cake from OzGrav. Looks like plenty to share?

Happy birthday to GW150914, our first (of many) #GravitationalWave discoveries, detected 10 years ago today!

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

https://ligo.org/science-summaries/GW230814/

#Astrodon#Physics

The gravitational-wave signal GW230814. The top panel shows the time-frequency representation of the signal where brighter regions indicate larger amplitude. The CWT acronym points to the method used to construct this time-frequency representation, based on the Continuous Wavelet Transform. The bottom panel shows the signal represented as a time series. The blue and purple lines show two different methods of reconstruction for the signal waveform. It is clear that the signal is a compact binary coalescence and the data are in good agreement with the reconstructions until the ringdown part. Being such a loud signal allows us to make this wonderfully precise reconstruction!

LIGO and Virgo will resume observing on 11 June joined by KAGRA! All four of our kilometre-scale #GravitationalWave detectors will observe at the same time!

Our observing run (O4) has been extended to run until 18 November 2025 and we are looking forward to many discoveries
