Grand Park Otaru Hotel), Otaru, Hokkaido Japan, SagittariusD (Sgr D) is one of the oldest known objects from the dawn of the radio astronomy in the Galactic center (GC). It has been considered a complex of HII regions. However, recent radio-continuum and infrared studies indicate that several components at various distances are projected along the same line of sight. In this presentation, we report the Suzaku discovery of a supernova remnant in the Sgr D complex, overturning the long-standing view of the object for 30 years (Sawada et al. 2009, PASJ). Our work is a nice illustration of the Suzaku's superb sensitivity for faint diffuse sources, which continues to revise our view of the GC region., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574059, レポート番号: JAXA-SP-09-008E}, pages = {160--161}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Suzaku identifies the true nature of an old friend in the Galactic center: SgrD}, volume = {JAXA-SP-09-008E}, year = {2010} }
