The black hole spin influence on accretion disk neutrino detection

Understand

Neutrinos are copiously emitted from black hole accretion disks playing a fundamental role in their evolution, as well as in the production of gamma ray bursts and r-process nucleosynthesis.

• The black hole generates a strong gravitational field able to change the properties of the emerging neutrinos.
• We study the influence of the black hole spin on the structure of the neutrino surfaces, neutrino luminosities, average neutrino energies, and event counts at SuperK.
• We consider several disk models and provide estimates that cover different black hole efficiency scenarios.
