Search for Gravitational Wave Memory in PPTA and EPTA Data: A Complete Signal Model

Sharon Mary Tomson, Boris Goncharov, Rutger van Haasteren +21

We perform searches for gravitational wave memory in the data of two major Pulsar Timing Array (PTA) experiments located in Europe and Australia. Supermassive black hole binaries (…

The NANOGrav 15 yr Data Set: Targeted Searches for Supermassive Black Hole Binaries

Nikita Agarwal, Gabriella Agazie, Akash Anumarlapudi +116

We present the first targeted searches for continuous gravitational waves (CWs) from 114 active galactic nuclei (AGN) that may host supermassive black hole binaries, using the NANO…

Beyond diagonal approximations: improved covariance modeling for pulsar timing array data analysis

Marco Crisostomi, Rutger van Haasteren, Patrick M. Meyers +1

Pulsar Timing Array (PTA) searches for nHz gravitational-wave backgrounds (GWBs) typically model time-correlated noise by assuming a diagonal covariance in Fourier space, neglectin…

On the calculation of p-values for quadratic statistics in Pulsar Timing Arrays

Rutger van Haasteren

Pulsar Timing Array (PTA) projects have reported various lines of evidence suggesting the presence of a stochastic gravitational wave (GW) background in their data. One key line of…

The NANOGrav 15-year Data Set: Search for Gravitational Wave Memory

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +102

We present the results of a search for nonlinear gravitational wave memory in the NANOGrav 15-year data set. We find no significant evidence for memory signals in the dataset, with…

The NANOGrav 15 yr Data Set: Harmonic Analysis of the Pulsar Angular Correlations

Gabriella Agazie, Jeremy G. Baier, Paul T. Baker +86

Pulsar timing array observations have found evidence for an isotropic gravitational wave background with the Hellings-Downs angular correlations, expected from general relativity.…
