ICECAT-1: the IceCube Event Catalog of Alert Tracks


This data release accompanies a report published in The Astrophysical Journal Supplement presenting the first IceCube Event Catalog of Alert Tracks (ICECAT-1), consisting of 275 neutrino events of likely astrophysical origin from 2011 to 2020.

Data release

The ICECAT-1 catalog represents the first catalog of alerts from the IceCube neutrino gold and bronze track alert program. Each catalog entry represents a single neutrino event potentially of astrophysical origin. This catalog includes alerts issued in real time via GCN notices/circulars as well as events observed in IceCube since the start of data collection with the complete IceCube detector in 2011 that would have triggered an alert had the program been in operation.
