Abstract: The long-time efforts invested in the neutrino astronomy field have recently paid off by the discovery of a diffuse neutrino flux of astrophysical origin by the IceCube detector. The incontrovertible evidence of the existence of cosmic sources producing neutrinos has brought up new questions in astroparticle physics, and opened the quest for the identification of those emitters. While neutrino astronomy has turned into a helpful means of investigation, a lot can be learnt by using it in synergy with other mature probes. In particular, the combination of neutrino/electromagnetic information is motivated by the fact that both radiations may be pictured in the same astrophysical particle-cascades scenario, cascades that are ultimately originated by cosmic rays. Based on these assumptions, limits can be placed on the known astrophysical source classes contribution to the diffuse neutrino flux. Furthermore, a promising ground for discovery is the search for transient and variable neutrino/electromagnetic sources, in which case the atmospheric neutrino and muon backgrounds can be reduced by taking time- and space-coincidence. Recent encouraging steps in this direction will be presented.
Speaker：Dr. Sara Buson got the PhD in 2013, at University of Padova. Currently, as junior Professor at Institut für Theoretische Physik und Astrophysik, Universität Würzburg and Visiting Assistant Research Scientist, University of Maryland. Dr. Buson’s list of publications holds more than 190 publications in major astrophysical journals with >20000 citations (h-index: 83), some of which are co-authored by virtue of membership in the Fermi-LAT collaboration. Accounting for all publications with substantial individual contributions since 2014 yields h-index: 17,
m-index: 3.4
