LIGO-VIRGO-O4b-16KHZ: Gravitational-Wave Strain Data from Virgo Detector

Parquet conversion of public gravitational-wave strain data from the Virgo detector V1 during the O4b observation run. The dataset contains time-domain samples converted from GWOSC HDF5 files for easier machine learning usage, with a sample rate of 16384 Hz and file durations of 4096 seconds. The dataset was created by PhysiQuanty and last updated on 2026-06-26.

Use Cases

• Train anomaly detection models for gravitational-wave signals based on the 16 kHz time-series strain data.
• Develop signal processing pipelines for continuous gravitational-wave searches based on the high-frequency strain samples.
• Benchmark time-series classification algorithms for astrophysical event detection based on the O4b observation run data.
• Perform data format conversion studies comparing Parquet and HDF5 for large-scale physics datasets.

Strengths

• Data is sourced from the authoritative Gravitational Wave Open Science Center (GWOSC).
• Files are converted to Parquet format, which is likely optimized for machine learning workflows.
• Sample rate is specified as 16384 Hz, indicating high temporal resolution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
