A new framework for lightning-fast gravitational wave analysis of pulsar timing data
Aiden Gundersen, Rutger van Haasteren, Neil J. Cornish +2
Pulsar timing array data analysis is computationally expensive, limiting the complexity of models which can be studied. As pulsar timing datasets and their respective models grow i…
Posterior Predictive Checks for Gravitational-wave Populations: Limitations and Improvements
Simona J. Miller, Sophia Winney, Katerina Chatziioannou +1
When selecting a model to characterize an astrophysical population, it is crucial to assess whether that model fits the data and, if not, how it can be improved. To this end, poste…
Model-agnostic gravitational-wave background characterization algorithm
Taylor Knapp, Patrick M. Meyers, Arianna I. Renzini
As ground-based gravitational-wave (GW) detectors improve in sensitivity, gravitational-wave background (GWB) signals will progressively become detectable. Currently, searches for…
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…
Rapid parameter estimation for pulsar-timing-array datasets with variational inference and normalizing flows
Michele Vallisneri, Marco Crisostomi, Aaron D. Johnson +1
In the gravitational-wave analysis of pulsar-timing-array datasets, parameter estimation is usually performed using Markov Chain Monte Carlo methods to explore posterior probabilit…
How to Detect an Astrophysical Nanohertz Gravitational-Wave Background
Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93
Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…
Stochastic Gravitational-Wave Backgrounds: Current Detection Efforts and Future Prospects
Arianna I. Renzini, Boris Goncharov, Alexander C. Jenkins +1
The collection of individually resolvable gravitational wave (GW) events makes up a tiny fraction of all GW signals which reach our detectors, while most lie below the confusion li…
