Titolo: | On the detectability of BL Lac objects by IceCube | Autori: | Righi, Chiara TAVECCHIO, Fabrizio |
Data pubblicazione: | 2017 | Titolo del volume in cui è pubblicato il poster: | 52nd Rencontres de Moriond : Very High Energy Phenomena in the Universe | Da pagina:: | arXiv:1708.01540 | Abstract: | Since 2010 IceCube observed around 50 high-energy neutrino events of cosmic origin above 60 TeV, but the astrophysical sources of these events are still unknown. We recently proposed high-energy emitting BL Lac (HBL) objects as candidate emitters of high-energy neutrinos. Assuming a direct proportionality between high-energy gamma-ray and very-high energy neutrino fluxes, we calculated the expected neutrino event number in a year for IceCube and the presently under construction Km3NeT. To give a value of the significance of a detection we considered also the background for the single sources. To this aim we derived the through-going muon rate, generated by muon neutrino including the effect of Earth absorption, the density of the Earth and the cross section $\nu N$. Applying this calculation both to HBL sources and the atmospherical neutrino background, we can calculate the expected significance of the detection by IceCube, showing that our scenario is compatible with a no detection of HBL. | Titolo del convegno: | 52nd Rencontres de Moriond : Very High Energy Phenomena in the Universe | Luogo del convegno: | La Thuile, Italy | Periodo del convegno: | 18-25 March, 2017 | URI: | http://hdl.handle.net/20.500.12386/27539 | URL: | http://moriond.in2p3.fr/VHEPU/2017/index.html | Bibcode ADS: | 2017arXiv170801540R | Fulltext: | open |
