THE GROUP OF INTERACTING SPIRAL GALAXY: HCG16 Abstract: Many early type spiral galaxies are called LINER, a Low Luminosity candidate, which indicate many galaxies have a massive blackhole. We observed some LINERs with ASCA and detected excess hard X-ray emission with powerlaw. However we must observe many galaxies to confirm that all the galaxies have a massive blackhole. Then we propose to observe the group of interacting early-type spiral galaxies to investigate that how fraction of galaxies in this group show AGN activity. Co-Is: 1 NAOKO IYOMOTO UNIV.
