A clearer view of gravitational-wave signals in pulsar timing arrays
An international team led by researchers at the @mpi_grav in Hannover, Germany, developed an improved noise model to analyze data from the European Pulsar Timing Array.

By addressing known limitations of how the noise contamination is modeled and therefore included in the analysis, the researchers have mitigated a tension between earlier studies of the data and the theoretical predictions.
According to their improved analysis, published in Nature Communications today, the EPTA data now better agree with a gravitational-wave background from coalescing black hole binaries in circular orbits. Additionally, the inferred background amplitude is in less tension with theoretical expectations.
