Pulsar-timing arrays will detect gravitational waves from supermassive black hole binaries. When?


We're like a spider at the center of a web...

I'm happy to report that the Astrophysical Journal just published a letter authored by our JPL/Caltech pulsar-timing group, in which we discuss how soon gravitational waves from the cosmic population of supermassive black holes could be detected by radio telescopes. We conclude that, notwithstanding recent negative results from the Parkes Pulsar Timing Array, we expect to have clear and convincing evidence of low-frequency gravitational waves within the next decade.

Our article was featured on the JPL homepage and in a NASA press release, and it was discussed in a Gizmodo article by Jennifer Ouellette.
