A Bayesian harmonic analysis of the NANOGrav 15-year data finds the pulsar angular correlations are dominated by a quadrupole consistent with general relativity, but an unexplained monopole at about 4 nHz reduces the quadrupole evidence when included.

The NANOGrav 15 yr Data Set: Harmonic Analysis of the Pulsar Angular Correlations
A Bayesian harmonic analysis of the NANOGrav 15-year data finds the pulsar angular correlations are dominated by a quadrupole consistent with general relativity, but an unexplained monopole at about 4 nHz reduces the quadrupole evidence when included.
