Data and Code for the 3–4 Solar Mass Compact-Remnant Gap Analysis

Chris Shreenan-Dyck published this reproducible data package on figshare in June 2026. It contains machine-readable datasets and notebooks supporting the analysis of a mass gap in compact astrophysical remnants. The package includes electromagnetic mass anchors for neutron stars, gravitational-wave event data, selection surfaces, prior configurations, and posterior samples.

Use Cases

• Reproducing the coherence mask and ceiling calculations based on the provided notebooks
• Performing posterior-predictive checks on compact-remnant mass inferences based on the event-level posterior samples
• Analyzing the selection surface for gravitational-wave detections based on the tabulated grid
• Validating the mass-gap analysis using the provided electromagnetic anchor and gravitational-wave event data

Strengths

• Includes posterior sample archives in HDF5 format for each referenced object
• Provides specific electromagnetic mass anchors for pulsars like PSR J1614-2230 and J0740+6620
• Contains a 78.9 KB ZIP file with structured data folders and runnable notebooks

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
