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 O4.
- Less-significant events are not shown by default. Press "Show All Public Events" to show significant and less-significant events.
O4 Significant Detection Candidates: 180 (200 Total - 20 Retracted)

0.000131197531503650704140.3 per year | RETRACTED ** This low-significance GW trigger was reported because the RAVEN pipeline found that it was coincident in time with Fermi/GBM trigger 758061038/250108855. However, that Fermi/GBM trigger ultimately was classified as a non-GRB (https://gcn.nasa.gov/circulars/38857, https://gcn.gsfc.nasa.gov/other/758061038.fermi). The GW trigger is not significant on its own, so a retraction Circular was issued (https://gcn.nasa.gov/circulars/38856). |
