Wow. What a great finding and a validation of the pulsar timing array approach. The numbers are mind boggling : very many pairs of supermassive black holes orbiting each other to eventually merge. The technical side of this study is quite precise, that being the slight advance or retardation of a given pulsar's signal due to a change in it's propagation to Earth from said pulsar. Put together this type of effect from very many pulsars - the more the merrier - and you have an enormous array. Goes to show that pulsars are the gift that just keeps on giving!
Cheers, Mike.

Hallo!
See also "A new view of the Universe". There is also a german version of this paper and links to the 6 original papers.
So we do wait for LISA, to fill the gap in wavelength between LIGO and PTA.
Kind regards and happy crunching
