X-PSI has been applied in the following studies. In addition to giving an idea of the scientific applications, these may also be useful for performance benchmarking and planning of computational resource consumption.

If you have used X-PSI for a project and would like to link it here, please contact the X-PSI team and/or submit a pull-request on GitHub.

Early X-PSI development

X-PSI was initiated by Thomas Riley as part of his PhD work at the University of Amsterdam. Chapter 3 of his PhD thesis (Riley 2019) provides an extended technical description of v0.1 of X-PSI and contains results of some parameter recovery tests using synthetic data.

NICER rotation-powered millisecond pulsar papers

X-PSI has been used in several Pulse Profile Modeling analysis papers using NICER data of rotation-powered millisecond pulsars. These are typically published with a Zenodo repository containing data, model files, X-PSI scripts, samples and post-processing notebooks to enable full reproduction and independent analysis.
