1 Astrophysical Interests (of Hyper-K and KNO) Kyujin Kwak (Ulsan National Institute of Science and Technology) On behalf of KNO/KNT astronomy working group July 8, 2018 ICHEP 2018 Satellite Meeting for Hyper-Kamiokande and KNO
2 Contents Hyper-K and KNO to open a new field of astrophysical research (multi-messenger astronomy) Current status and activities of KNO/KNT astronomy working group Some scientific topics
3 Hyper-K and KNO Advantage of KNO in the view of astronomy Higher sensitivity thanks to larger overburden Comparison of Cosmic Ray Flux between HK & KNO (From S-B Kim s slide)
4 Astrophysical Neutrinos (Optically) Failed SNe (?) GRB/AGN as neutrino sources in the energetic jet via Halzen, Francis Nuovo Cim. C037 (2014) no.03, , Astron.Nachr. 335 (2014) 507
5 Astronomy and Astrophysics in Korea Relatively a large community in optical and radio astronomy for historical reason in comparison with high energy astrophysics including space program Korea Astronomy and Space science Institute (KASI) Giant Magellan Telescope Korean VLBI Network (KVN)
6 A&A in Korea (cont d) Recently other astronomy-related research fields are growing rapidly: astro-particle physics including neutrino astrophysics, nuclear astrophysics, and gravitational wave Institute of Basic Science (IBS) RAON (Nuclear Astrophysics) Korea Aerospace Research Institute KGWG
