Estimation of the neutrino flux and resulting constraints on hadronic emission models for Cyg X-3 using AGILE data    [PDF]

Philipp Baerwald, Dafne Guetta

In this work we give an estimate of the neutrino flux that can be expected from the microquasar Cyg X-3. We calculate the muon neutrino flux expected here on Earth as well as the corresponding number of neutrino events in the IceCube telescope based on the so-called "hypersoft" X-ray state of Cyg X-3. If the average emission from Cyg X-3 over a period of 5 years were as high as during the used X-ray state, a total of 0.1 events should be observed by the full IceCube telescope. Using the correlation of AGILE data on the flaring episodes in 2009 Jun.-Jul. to soft X-ray states we calculate that the upper limits on the neutrino flux given by IceCube are starting to constrain the hadronic models, which have been introduced to interpret the high energy emission detected by AGILE.
