Forward Shock Proper Motions of Kepler's Supernova Remnant
Satoru Katsuda, Hiroshi Tsunemi, Hiroyuki Uchida +1
The X-ray structure of Kepler's supernova remnant shows a rounded shape delineated by forward shocks. We measure proper motions of the forward shocks on overall rims of the remnant…
Another Abundance Inhomogeneity in the South East Limb of the Cygnus Loop
Hiroshi Tsunemi, Masashi Kimura, Hiroyuki Uchida +2
We have observed the south-east (SE) limb of the Cygnus Loop with {\it Suzaku}. Our spatially-resolved spectroscopic study shows that a one- non-equilibrium ionizati…
Suzaku Observations across the Cygnus Loop from the Northeastern to the Southwestern Rim
Masashi Kimura, Hiroshi Tsunemi, Satoru Katsuda +1
We have observed the Cygnus Loop from the northeast (NE) rim to the southwest (SW) rim using Suzaku in 10 pointings that is just north of previous XMM-Newton observations. The obse…
The Plasma Structure of the Southwestern Region of the Cygnus Loop with the XMM-Newton Observatory
Hiroyuki Uchida, Hiroshi Tsunemi, Satoru Katsuda +1
We observed the southwestern region of the Cygnus Loop in two pointings with \textit{XMM-Newton}. The region observed is called the "blow-out" region that is extended further in th…
Chandra Observations of the Northeastern Rim of the Cygnus Loop
Satoru Katsuda, Hiroshi Tsunemi, Masashi Kimura +1
We present results from spatially resolved spectral analyses of the northeastern (NE) rim of the Cygnus Loop supernova remnant (SNR) based on two Chandra observations. One pointing…
Discovery of Fast-Moving X-Ray--Emitting Ejecta Knots in the Oxygen-Rich Supernova Remnant Puppis A
S. Katsuda, K. Mori, H. Tsunemi +5
We report on the discovery of fast-moving X-ray--emitting ejecta knots in the Galactic Oxygen-rich supernova remnant Puppis A from XMM-Newton observations. We find an X-ray knotty…
The Slow X-Ray Expansion of the Northwestern Rim of the Supernova Remnant RX J0852.0-4622
S. Katsuda, H. Tsunemi, K. Mori
The detection of radioactive decay line of 44Ti provides a unique evidence that the gamma-ray source is a young (< 1,000 yr) supernova remnant because of its short lifetime of abou…
Asymmetric Ejecta Distribution of the Cygnus Loop revealed with Suzaku
S. Katsuda, H. Tsunemi, E. Miyata +4
We observed a linearly sliced area of the Cygnus Loop from the north-east to the south-west with Suzaku in seven pointings. After dividing the entire fields of view (FOV) into 119…
The Plasma Structure of the Cygnus Loop from the Northeastern Rim to the Southwestern Rim
Hiroshi Tsunemi, Satoru Katsuda, Norbert Nemes +1
The Cygnus Loop was observed from the northeast to the southwest with XMM-Newton. We divided the observed region into two parts, the north path and the south path, and studied the…
Suzaku Observations of the North Polar Spur: Evidence for Nitrogen Enhancement
Eric D. Miller, Hiroshi Tsunemi, Mark W. Bautz +10
We present observations of the North Polar Spur (NPS) using the X-ray Imaging Spectrometer (XIS) aboard the Suzaku X-ray satellite. The NPS is a large region of enhanced soft X-ray…
X-Ray Spectroscopy of SN 1006 with Suzaku
Hiroya Yamaguchi, Katsuji Koyama, Satoru Katsuda +7
We report on observations of SN 1006 with the X-ray Imaging Spectrometers (XIS) on board Suzaku. We firmly detected K-shell emission from Fe, for the first time, and find that the…
Performance of the Charge Injection Capability of Suzaku XIS
H. Nakajima, H. Yamaguchi, H. Matsumoto +17
A charge injection technique is applied to the X-ray CCD camera, XIS (X-ray Imaging Spectrometer) onboard Suzaku. The charge transfer inefficiency (CTI) in each CCD column (vertica…
Monte-Carlo Simulator and Ancillary Response Generator of Suzaku XRT/XIS System for Spatially Extended Source Analysis
Y. Ishisaki, Y. Maeda, R. Fujimoto +31
We have developed a framework for the Monte-Carlo simulation of the X-Ray Telescopes (XRT) and the X-ray Imaging Spectrometers (XIS) onboard Suzaku, mainly for the scientific analy…
Spatially Resolved X-ray Spectroscopy of Vela Shrapnel A
S. Katsuda, H. Tsunemi
We present the detailed X-ray spectroscopy of Vela shrapnel A with the XMM-Newton satellite. Vela shrapnel A is one of several protrusions identified as bullets from Vela supernova…
Spatially Resolved Spectral Analysis of Vela Shrapnel D
Satoru Katsuda, Hiroshi Tsunemi
The ROSAT all-sky survey discovered several `shrapnels', showing boomerang structures outside the Vela supernova remnant. We observed shrapnel D with the XMM-Newton satellite. Ther…
