ANTARES search for high-energy neutrinos from TeV-emitting blazars, Markarian 421 and 501, in coincidence with HAWC gamma-ray flares
Description
Neutrinos are unique messengers for detecting violent phenomena in the Universe. Potential sources of cosmic neutrinos are, for example, Active Galactic Nuclei (AGNs) or Gamma- Ray Bursts (GRBs). In the case of hadronic cosmic rays acceleration, the production of neutrinos is possibly accompanied by high-energy gamma-ray emissions. The search for coincidences between high-energy neutrinos detected by the ANTARES neutrino telescope and gamma-rays detected by the HAWC gamma-ray observatory is presented. Searching in a particular time window significantly reduces the background noise in the neutrino data and thus increases the discovery potential. In this thesis, the results of a search for neutrinos detected in correlation with a gamma-ray signal from two particular AGNs, Markarian 421 and Markarian 501, are presented. As the blazars closest to Earth, they are excellent sources for testing the blazar-neutrino connection scenario, especially during the increase of their activities (flares) in which the search for neutrinos may have a higher detection probability.

Abstract (French)
Les neutrinos sont des messagers uniques pour detecter les phenomenes violents de l'Univers. Les sources potentielles de neutrinos cosmiques sont, par exemple, les Noyaux Actifs de Galaxie (NAGs), ou les sursauts gammas. Dans le cas d'un accelerateur astrophysique de rayons cosmiques hadroniques, la production de neutrinos s'accompagne eventuellement d'emissions gammas de haute energie. La recherche des coincidences entre des neutrinos de haute energie detectes avec le telescope a neutrinos ANTARES et des photons gamma captes par l'observatoire HAWC est presentee. La recherche dans une fenetre temporelle particuliere reduit le bruit de fond de maniere significative dans les donnees du telescope a neutrinos et augmente donc le potentiel de decouverte. Dans cette these, les resultats de la recherche de neutrinos detectes en correlation avec un signal gamma en provenance de 2 NAG particulier, Markarian 421 et Markarian 501, sont presentes. En tant que blazars les plus proches de la Terre, ils constituent d'excellentes sources pour tester le scenario de connexion blazar-neutrinos, en particulier lors de leurs 'bouffees' d'activites (flares) pour lesquelles la recherche de neutrinos en fonction du temps peut presenter une probabilite de detection plus elevee.
