본 그룹은 초대질량 블랙홀과 관련된 관측 천체물리학을 연구하며, 특히 블랙홀 주변 물질 유입과 분출, 블랙홀 근처에서 기원하는 전자기파와 중성미자 다중 신호 분석, 그리고 우주초기 블랙홀의 기원과 분포를 중점적으로 다룹니다. 지상 및 우주 망원경을 활용한 데이터 분석과 다양한 기관과의 국제 협력을 통해 연구를 진행하고 있습니다. 또한 암흑물질과 우주론적 현상에 대한 연구도 진행하며, 차세대 망원경 및 관측미션들의 설계 그리고 대규모 데이터 처리 기술 개발 등도 수행하고 있습니다.
Our group conducts research in observational astrophysics, focusing on supermassive black holes, particularly the accretion and outflow processes around black holes, the analysis of electromagnetic waves and neutrino multi-messenger signals originating near black holes, and the origins and distributions of early-universe black holes. We carry out research by analyzing data from ground- and space-based telescopes and through international collaborations with various institutions. Additionally, we are engaged in studies of dark matter and cosmological phenomena, while also contributing to the design of next-generation telescopes and observational missions, as well as the development of large-scale data processing technologies.
