X-ray Proper Motions and Shock Speeds along the Northwest Rim of SN 1006
Satoru Katsuda, Knox S. Long, Robert Petre +3
We report the results of an X-ray proper motion measurement for the NW rim of SN1006, carried out by comparing Chandra observations from 2001 and 2012. The NW limb has predominantl…
High-Resolution X-Ray Spectroscopy of the Galactic Supernova Remnant Puppis A with the XMM-Newton RGS
Satoru Katsuda, Hiroshi Tsunemi, Koji Mori +6
We present high-resolution X-ray spectra of cloud-shock interaction regions in the eastern and northern rims of the Galactic supernova remnant Puppis A, using the Reflection Gratin…
Discovery of a Pulsar Wind Nebula Candidate in the Cygnus Loop
Satoru Katsuda, Hiroshi Tsunemi, Koji Mori +4
We report on a discovery of a diffuse nebula containing a pointlike source in the southern blowout region of the Cygnus Loop supernova remnant, based on Suzaku and XMM-Newton obser…
A Suzaku Study of Ejecta Structure and Origin of Hard X-ray Emission in the Supernova Remnant G156.2+5.7
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +3
We report an X-ray study of the evolved Galactic supernova remnant (SNR) G156.2+5.7 based on six pointing observations with Suzaku. The remnant's large extent (100$\arcmin$ in diam…
Elemental Abundances in the Possible Type Ia Supernova Remnant G344.7-0.1
Hiroya Yamaguchi, Masaomi Tanaka, Keiichi Maeda +5
Recent studies on the Galactic supernova remnant (SNR) G344.7-0.1 have commonly claimed its origin to be a core-collapse supernova (SN) explosion, based on its highly asymmetric mo…
