An intriguing event has just been detected by the IceCube neutrino telescope!

This event has a 90.0% chance to be a neutrino of astrophysical origin. An event as significant or more should be produced by the background noise every 1174 days in average.

Its energy is estimated to be around 61 TeV ¹ and its source is located with a 90% probability to be within a zone of 17040.75 square deg ².

Is it the result of a blazar, a supernovae…? This alert has been sent to astronomers around the world so they can point their telescopes toward the source of this event. An other signal from a different messenger could allow to identify the source and understand the mechanisms powering this emission.

Complete set of information:

This event has been detected on 2023-04-30T08:42:02.639734 UTC (Coordinated Universal Time).
The algorithm estimates its source location to be around the following coordinates: right ascension = 23.9720 degrees, declination = 38.9953 degrees with a 90% probability to be within a disk of radius 4799.3 arcmin and a 50% probability to be within a disk of 2633.2 arcmin radius.
The uncertainty in the location of the event is based on statistical uncertainty only, not accounting for the systematic error which should be smaller. The estimated energy is 6.18754*10^1 TeV.
The background noise should produce an event at least as significant 0.31 times per year which leads to a probability of 90.00% that this event is a track-like neutrino of astrophysical origin.

The figure below is the estimated localisation of this event’s source we have from the signal. The yellow area corresponds to the most probable zone.
