Description
IceCube Neutrino Observatory has recently detected over 30 very high-energy neutrino events which are most likely of cosmic origin.  Due to poor angular resolution of cascade-type events, which dominate the event list, identification of astrophysical source(s) as origin of these neutrino events is proving to be difficult.   I will present a scenario where a subset of cosmic neutrino events originate from the Fermi Bubbles at the Galactic center and the rest originate from extragalactic sources, which could be the sources of ultrahigh-energy cosmic rays as well.  Expected multi-messenger signal and statistical analysis will be discussed in support of this scenario.
