The International Pulsar Timing Array (IPTA) is a consortium of consortia, comprised of the European PTA (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the Indian Pulsar Timing Array Project (InPTA), and the Parkes PTA (PPTA).

When pulsars that are not observed by one PTA are added in using another PTA's data, there is an increase in the signal-to-noise ratio (SNR) of the GW background

Good question! We hope that by combining our datasets, that the @IPTA_GW will have a good chance at making an even more precise measurement of the background.

@Dr_CMingarelli My understanding is that detection is currently at the 4 sigma level - how long do you anticipate it will be before it reaches 5 sigma?

Australian astronomers have announced the strongest hint yet of low-frequency gravitational waves from supermassive black hole pairs! @Swinburne @ARC_OzGRav @CSIRO_ATNF iopscience.iop.org/article/10.384…

The IPTA looks forward to continuing this collaborative work with the combination of individual PTA datasets into the third IPTA data release (IPTA DR3). This mega data set is expected to be more sensitive than any individual PTA data set.

Each individual PTA publication represents years of work by many scientists within each collaboration. In addition, scientists have been working together across PTA collaborations to share knowledge and cutting edge analysis techniques to further the scientific goals of PTAs.
