Introduction (Kor) : 허블 우주망원경과 수바루 망원경을 이용하여 하늘에서 두번째로 SZ 효과가 큰 PLCK G287.0+32.9 은하단의 암흑물질 연구
Introduction (Eng) : The second most significant detection of the Planck Sunyaev−Zel'dovich survey, PLCK G287.0+32.9 (z = 0.385), boasts two similarly bright radio relics and a radio halo. A key missing puzzle for the merging scenario reconstruction is the underlying dark matter distribution in high resolution. We present a joint Subaru Telescope and Hubble Space Telescope weak-lensing analysis of the cluster. Our analysis shows that the mass distribution features four significant substructures.
