Kenji Toma（Creative Interdisciplinary Research Division） "NEUTRINO AND COSMIC-RAY EMISSION AND CUMULATIVE BACKGROUND FROM RADIATIVELY INEFFICIENT ACCRETION FLOWS IN LOW-LUMINOSITY ACTIVE GALACTIC NUCLEI", 2015 ApJ 806 159 Kenji TOMA has proposed a new theoretical model explaining the origin of recently observed high-energy astrophysical neutrinos in collaboration with Shigeo KIMURA and Kohta MURASE (Pennsylvania State University). Neutrino is one of the elementary particles and well known since Prof. KOSHIBA received a Nobel Prize on the first detection of astrophysical neutrinos. Recently, neutrinos with about 10 millions times higher energies than detected by Prof. KOSHIBA have been observed with a huge detector in Antarctica. Their origin is being a mystery. K. TOMA has proposed a new theoretical model in which they are produced in the vicinities of super massive black holes at the center of ordinary galaxies. This model also implies new possible studies investigating physical conditions around the black holes and history of galaxy evolutions with neutrino observations. This work has been published in “Astrophysical Journal” of the American Astronomical Society. Shigeo S. Kimura, Kohta Murase and Kenji Toma 2015 ApJ 806 159 doi:10.1088/0004-637X/806/2/159
