LIGO/Virgo/KAGRA Public Alerts
- More details about public alerts are provided in the LIGO/Virgo/KAGRA Alerts User Guide.
- Retractions are marked in red. Retraction means that the candidate was manually vetted and is no longer considered a candidate of interest.
- Less-significant events are marked in grey, and are not manually vetted. Consult the LVK Alerts User Guide for more information on significance in O4c.
- Less-significant events are not shown by default. Press "Show All Public Events" to show significant and less-significant events.
O4c Significant Detection Candidates: 1659 (1659 Total - 0 Retracted)
