Abstract:
We present a catalog of likely astrophysical neutrino track-like
events from the IceCube Neutrino Observatory. IceCube began reporting
likely astrophysical neutrinos in 2016, and this system was updated in
2019. The catalog presented here includes events that were reported in
real time since 2019, as well as events identified in archival data
samples starting from 2011. We report 275 neutrino events from two
selection channels as the first entries in the catalog, the IceCube
Event Catalog of Alert Tracks, which will see ongoing extensions with
additional alerts. The Gold and Bronze alert channels respectively
provide neutrino candidates with a 50% and 30% probability of being
astrophysical, on average assuming an astrophysical neutrino power-law
energy spectral index of 2.19. For each neutrino alert, we provide the
reconstructed energy, direction, false-alarm rate, probability of
being astrophysical in origin, and likelihood contours describing the
spatial uncertainty in the alert's reconstructed location. We also
investigate a directional correlation of these neutrino events with
gamma-ray and X-ray catalogs, including 4FGL, 3HWC, TeVCat, and
Swift-BAT.
Description:
We compile the neutrino alert catalog by applying the procedures of
event selection described in Section 3 followed by likelihood scans on
IceCube data going back to 2011 May.

Note (1):
* = Event also triggered IceTop and are likely due to cosmic-ray showers.
Note (2): The signalness quantity assigns a probability of being an
astrophysical neutrino to each alert event, assuming the same E-2.19
astrophysical neutrino spectrum. The alert generation criteria are
optimized such that "Bronze" alerts have an average signalness value
between 30% and 50%, whereas "Gold" candidates have an average
signalness above 50%. Thus, the Gold stream has a higher signal purity.
The "signalness" is defined in Equation 1 as:
Signalness(E,δ)=
Nsignal(E,δ)/(Nsignal(E,δ)+Nbackground(E,δ))
Here E is the reconstructed event energy, δ is the event decl.,
and Nsignal(E,δ) and Nbackground(E,δ) are the expected
number of signal and background events at decl.
See Section 2.2.
