A high-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056. Prompted by this association, we inve ... 

High-Energy Neutrinos from Blazar Flares and Implications of TXS 0506+056

Motivated by the observation of a > 290 TeV muon neutrino by IceCube, coincident with a ~6 month-long γ-ray flare of the blazar TXS 0506+056, and an archival search which revealed 13 ± 5 further,

Neutrinos from TXS 0506+056 prior to the 2017 gamma-ray flare

On 2017 September 22, IceCube released a public alert announcing the detection of a well-reconstructed, high-energy neutrino event. Such alerts issued through the Extremely High Energy (EHE) alert

Probing New Physics From TXS 0506+056 Blazar Neutrinos

Supported by the recent detection of a TXS 0506+056 blazar neutrino with an energy in the TeV-PeV range detected by the IceCube experiment, a probe of a new physics scale LNP related to high-energy

Cosmic hadron colliders

An ultrahigh-energy neutrino event detected with the IceCube detector in Antarctica, simultaneous and co-spatial with a multi-wavelength outburst of a blazar about 3 billion light years away, points

Photohadronic Model for the Neutrino and Gamma-Ray Emission from TXS 0506+056

The detection of a high-energy muon neutrino on 2017 September 22 by the IceCube neutrino detector coincides with the multiwavelength flaring from the BL Lac object TXS 0506+056, most likely

Neutrino emission from the direction of the blazar TXS 0506+056 prior to the IceCube-170922A alert

High-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056, suggesting that blazars are identifiable sources of the high-energy astrophysical neutrinos flux.

Next generation neutrino detectors at the South Pole

Since the construction of IceCube was completed in 2010/11, the observatory has delivered several outstanding measurements in neutrino physics and multimessenger astronomy. Additionally, a series of

AGILEγ-ray sources coincident with cosmic neutrino events

Using data obtained by theγ-ray imager on board of the AGILE satellite, we systematically searched for transientγ-ray sources above 100 MeV in temporal and spatial coincidence with high-energy

On the Neutrino Flares from the Direction of TXS 0506+056

A multimessenger campaign has associated a high-energy cosmic neutrino with a distant gamma-ray blazar, TXS 0506+056. IceCube archival data subsequently revealed that the high-energy neutrino flux

The IceCube Coincident Neutrino Event is Unlikely to be Physically Associated with LIGO/Virgo S190728q

The IceCube neutrino event detected 360 s before the trigger of LIGO/Virgo S190728q is unlikely to be physically associated with the GW event because of an energy budget reason.



Neutrino emission from the direction of the blazar TXS 0506+056 prior to the IceCube-170922A alert

High-energy neutrino event detected by IceCube on 22 September 2017 was coincident in direction and time with a gamma-ray flare from the blazar TXS 0506+056, suggesting that blazars are identifiable sources of the high-energy astrophysical neutrinos flux.

Search for a cumulative neutrino signal from blazar flares using IceCube data

Blazars are active galactic nuclei which have their relativistic particle jet pointing towards Earth and have been observed to emit gamma rays to very high energies. They are also candidates for

The Redshift of the BL Lac Object TXS 0506+056

The bright BL Lac object TXS 0506+056 is the most likely counterpart of the IceCube neutrino event EHE 170922A. The lack of this redshift prevents a comprehensive understanding of the modeling of the

Active galactic nuclei (AGN) are believed to be promising candidates of extragalactic cosmic-ray accelerators and sources, and associated high-energy neutrino and hadronic gamma-ray emission has been

Evidence for High-Energy Extraterrestrial Neutrinos at the IceCube Detector

The presence of a high-energy neutrino flux containing the most energetic neutrinos ever observed is revealed, including 28 events at energies between 30 and 1200 TeV, although the origin of this flux is unknown and the findings are consistent with expectations for a neutRino population with origins outside the solar system.

Observation of high-energy astrophysical neutrinos in three years of IceCube data.

Results from an analysis with a third year of data from the complete IceCube detector are consistent with the previously reported astrophysical flux in the 100 TeV-PeV range at the level of 10(-8)  GeV cm-2 s-1 sr-1 per flavor and reject a purely atmospheric explanation for the combined three-year data at 5.7σ.
