Title: Constraining the origin of IceCube’s neutrinos with HAWC. Abstract: IceCube has observed an astrophysical isotropic flux of neutrinos in the 10 TeV - 8 PeV range. Though an extragalactic origin is usually assumed, no unequivocal association with astrophysical objects has been made. It is often assumed that the neutrino sources are also cosmic ray sources … Continue reading "CRA seminar (Prof. Ignacio Taboada)"

CRA seminar by Dr. Inayoshi (Columbia University) Title: Hyper-Eddington accretion flows onto massive black holes Abstract: How fast can black holes (BHs) grow?  The existence of bright quasars at high-redshift provides a challenging puzzle about the origin of supermassive BHs. To form such massive objects within a billion year, rapid growth of seed BHs is required. We … Continue reading "CRA seminar (Dr. Kohei Inayoshi)"
