About Gravitational Wave Events
Receive alerts of Gravitational Wave Events from the LIGO/Virgo/KAGRA Collaboration (LVK) on your iPhone.
This is an app for both the LIGO/Virgo/KAGRA Community and the general public. It provides low latency alerts using the Open Public Alerts currently being deployed by the Gamma-ray Coordinates Network (GCN) through GCN/LVK Notices (https://emfollow.docs.ligo.org/userguide/). To receive alerts using the app just select the category of alerts you wish to receive - it's that simple!
The O3 observing run ended in March 2020. O4 is expected to start in May 2023. The app will download all O4 events and counterparts as they are reported through a GCN Notice in addition to any related GCN Circulars. The app database is pre-populated with selected Notices and Circulars from all previous O1, O2 and O3 events. The app retains Notices for one Mock Event reported through GCN for testing purposes. (For information on LIGO/Virgo/KAGRA Collaboration GCN Notices see: https://gcn.gsfc.nasa.gov/lvc.html .)
Includes an interactive sky map showing the location of each event.
The app also has a public Message exchange bulletin board and some interesting Links. The Links provide information on Gravitational Waves and the LIGO and Virgo observatories.
