SUMMARY:High-energy emissions from neutron star mergers\, NPAC (Nuclea
 r/Particle/Astro/Cosmo) Forum\, Shigeo Kimura\, PennState
DESCRIPTION:Last year\, LIGO-VIRGO collaborations reported detection o
 f the first neutron star merger event\, GW170817\, which accompanied w
 ith observations of electromagnetic counterparts from radio to gamma r
 ays. High-energy gamma rays and neutrinos were not observed. However\,
  the mergers of neutron stars are expected to produce these high-energ
 y particles. Relativistic jets are expected to be launched when the ne
 utron stars merge\, which can be a source of high-energy neutrinos.  A
 lso\, the central remnant object after the merger event\, either a bla
 ck hole or a neutron star\, can produce high-energy photons weeks to m
 onths after the merger. In addition\, the neutron star mergers produce
  massive and fast ejecta\, which can be a source of Galactic high-ener
 gy cosmic rays\, analogous to supernova remnants. In this talk\, I wil
 l discuss these high-energy processes and prospects for multi-messenge
 r detections related to the neutron star mergers .
