Draw me a Neutrino: the first KM3NeT art contest
No full text[EN] While the KM3NeT neutrino detector is being deployed in the Mediterranean Sea, the Collaboration
launched a contest searching for illustrations of the neutrinos it will detect. The participants
in the contest were invited to submit their interpretation of a neutrino, using any technique. More
than 500 drawings were submitted from sixteen different countries. The winners were selected
by a jury of scientists, artists and science communicators based on the originality and creativity
of the drawings, as well as the harmony with the properties and origin of the neutrinos. After
announcing the results in an online ceremony with a large international audience, the winning
drawings have been put on display in a dedicated KM3NeT Virtual Neutrino Art Centre. In this
contribution, we will explain the motivation for the contest and will describe how it was organized.
We will also show the winning drawings and present the results of an impact study carried out
during the contest.We thank Angelo Ceres of Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Bari, for
setting up the contest website. The contest was supported in France from Centre National de la
Recherche Scientifique (CNRS) and LabEx UnivEarthS (ANR-10-LABX-0023 and ANR-18-IDEX0001). G. de Wasseige acknowledges support from the European Union¿s Horizon 2020 research

Search for neutrino counterparts to the gravitational wave sources from LIGO/Virgo O3 run with the ANTARES detector
No full textSince 2015 the LIGO and Virgo interferometers have detected gravitational waves from almost one hundred coalescences of compact objects (black holes and neutron stars). This article presents the results of a search performed with data from the ANTARES telescope to identify neutrino counterparts to the gravitational wave sources detected during the third LIGO/Virgo observing run and reported in the catalogues GWTC-2, GWTC-2.1, and GWTC-3. This search is sensitive to all-sky neutrinos of all flavours and of energies > 100 GeV, thanks to the inclusion of both track-like events (mainly induced by ¿µ chargedcurrent interactions) and shower-like events (induced by other interaction types). Neutrinos are selected if they are detected within ±500 s from the GW merger and with a reconstructed direction compatible with its sky localisation. No significant excess is found for any of the 80 analysed GW events, and upper limits on the neutrino emission are derived. Using the information from the GW catalogues and assuming isotropic emission, upper limits on the total energy Etot,¿ emitted as neutrinos of all flavours and on the ratio f¿ = Etot,¿/EGW between neutrino and GW emissions are also computed. Finally, a stacked analysis of all the 72 binary black hole mergers (respectively the 7 neutron star-black hole merger candidates) has been performed to constrain the typical neutrino emission within this population, leading to the limits: Etot,¿ < 4.0 × 1053 erg and f¿ < 0.15 (respectively, Etot,¿ < 3.2 × 1053 erg and f¿ < 0.88) for E-2 spectrum and isotropic emission. Other assumptions including softer spectra and non-isotropic scenarios have also been testedPeer ReviewedA. Albert, S. Alves, M. André, M. Ardid, S. Ardid, J.-J. Aubert, J. Aublin, B. Baret, S.

Constraining the contribution of Gamma-Ray Bursts to the high-energy diffuse neutrino flux with 10 years of ANTARES data
No full textAddressing the origin of the observed diffuse astrophysical neutrino flux is one of the main challenges in the context of the neutrino astronomy nowadays. Among several astrophysical sources, Gamma-Ray Bursts (GRBs) are considered interesting candidates to be explored. Indeed, being the most powerful explosions observable in the Universe, they are potentially able to achieve the energetics required to reproduce the neutrino flux. Thus, they are expected to provide at least some contribution to the astrophysical diffuse neutrino flux. Within the framework of the fireball model, mesons can be produced during photo-hadronic interactions occurring in the internal shocks between shells emitted by the central engine; from their decays, high-energy gamma rays and neutrinos are expected to be generated. Within this scenario, the results of a stacked search for astrophysical muon neutrinos performed in space and time coincidence with 784 GRBs in the period 2007-2017 using ANTARES data are presented. The neutrino flux expectation from each GRB detectable by ANTARES was calculated in the framework of the classical internal shock model. Given the absence of coincident neutrinos, the contribution of the detected GRB population to the neutrino diffuse flux is constrained to be less than 10% around 100 TeV. In addition, the systematic uncertainties on the diffuse flux are computed by propagating to the stacked limit the uncertainties on the model parameters for each individual burst.Article signat per 142 autors/es: A.

ANTARES search for neutrino flares from the direction of radio-bright blazars
No full textIn 2017, a high-energy muon neutrino detected by IceCube was found positionally coincident with the direction of a known blazar, TXS 0506+056, in a state of enhanced 훾-ray emission. Soon after, IceCube reported a compelling evidence for an earlier neutrino flare from the same direction found in the archival data, this time not accompanied by any observed electromagnetic activity. The IceCube findings suggest searching for flaring neutrino emissions from astrophysical sources, not necessarily accompanied by flares detected in y-rays. The analysis presented in this contribution scans the events collected by the ANTARES neutrino telescope in 13 years of data taking in a search for clustering in space and time. The analysis method is based on an unbinned maximum likelihood approach. Generic Gaussian and Box profiles are assumed for the signal time emission, with both the central time and duration of the flare being free parameters in the likelihood maximization. The time-dependent approach is applied to the catalog of radio-bright blazars for which a promising directional correlation with IceCube muon tracks was recently reported [ApJ 894 (2020) 101, ApJ 908 (2021) 157].Article signat per 147 autors/es: A.

Searches for point-like sources of cosmic neutrinos with 13 years of ANTARES data
No full textThe main goal of the ANTARES neutrino telescope is the identification of neutrinos from astrophysical sources. Thanks to its location in the Northern hemisphere, ANTARES can rely on an advantageous view of the Southern Sky, in particular for neutrino energies below 100 TeV. This feature, combined with a very good angular resolution for high-quality selected events, makes the telescope an excellent tool to test for the presence of point-like sources, especially of Galactic origin. In ANTARES, track-like events are reconstructed with a median angular resolution of 0.4º while for shower-like events a median angular resolution of 3º is achieved. The ANTARES Collaboration published the result of the search for cosmic point-like neutrino sources using track-like and shower-like events collected during nine years of data taking [Phys. Rev. D 96 (2017) 082001]. In this contribution, the update to this analysis using a total of 13 years of data recorded between early 2007 and early 2020 (3845 days of livetime) is presented. Moreover, the results of the dedicated searches for neutrino candidates from the tidal disruption events AT2019dsg and AT2019fdr, recently indicated as the most likely counterparts of two high-energy IceCube neutrinos, IC191001A and IC200530A, are reported.Article signat per 142 autors/es: A.

Constraining the contribution of Gamma-Ray Bursts to the high-energy diffuse neutrino flux with 10 years of ANTARES data
No full textAddressing the origin of the observed diffuse astrophysical neutrino flux is one of the main challenges in the context of the neutrino astronomy nowadays. Among several astrophysical sources, Gamma-Ray Bursts (GRBs) are considered interesting candidates to be explored. Indeed, being the most powerful explosions observable in the Universe, they are potentially able to achieve the energetics required to reproduce the neutrino flux. Thus, they are expected to provide at least some contribution to the astrophysical diffuse neutrino flux. Within the framework of the fireball model, mesons can be produced during photo-hadronic interactions occurring in the internal shocks between shells emitted by the central engine; from their decays, high-energy gamma rays and neutrinos are expected to be generated. Within this scenario, the results of a stacked search for astrophysical muon neutrinos performed in space and time coincidence with 784 GRBs in the period 2007-2017 using ANTARES data are presented. The neutrino flux expectation from each GRB detectable by ANTARES was calculated in the framework of the classical internal shock model. Given the absence of coincident neutrinos, the contribution of the detected GRB population to the neutrino diffuse flux is constrained to be less than 10% around 100 TeV. In addition, the systematic uncertainties on the diffuse flux are computed by propagating to the stacked limit the uncertainties on the model parameters for each individual burst.Article signat per 142 autors/es: A.

Searches for point-like sources of cosmic neutrinos with 13 years of ANTARES data
No full textThe main goal of the ANTARES neutrino telescope is the identification of neutrinos from astrophysical sources. Thanks to its location in the Northern hemisphere, ANTARES can rely on an advantageous view of the Southern Sky, in particular for neutrino energies below 100 TeV. This feature, combined with a very good angular resolution for high-quality selected events, makes the telescope an excellent tool to test for the presence of point-like sources, especially of Galactic origin. In ANTARES, track-like events are reconstructed with a median angular resolution of 0.4º while for shower-like events a median angular resolution of 3º is achieved. The ANTARES Collaboration published the result of the search for cosmic point-like neutrino sources using track-like and shower-like events collected during nine years of data taking [Phys. Rev. D 96 (2017) 082001]. In this contribution, the update to this analysis using a total of 13 years of data recorded between early 2007 and early 2020 (3845 days of livetime) is presented. Moreover, the results of the dedicated searches for neutrino candidates from the tidal disruption events AT2019dsg and AT2019fdr, recently indicated as the most likely counterparts of two high-energy IceCube neutrinos, IC191001A and IC200530A, are reported.Article signat per 142 autors/es: A.
