Suzaku Observation of HESS J1825-137: Discovery of Largely-Extended X-rays near from PSR J1826-1334 (2008)

Uchiyama, H., Matsumoto, H., Tsuru, T. G., Koyama, K., Bamba, A.

We observed the brightest part of HESS J1825-137 with the Suzaku XIS, and found diffuse X-rays extending at least up to 15' (~ 17 pc) from the pulsar PSR J1826-1334. The spectra have no emission...

Suzaku Observations of Tycho's Supernova Remnant (2008)

Tamagawa, T., Hayato, A., Nakamura, S., Terada, Y., Bamba, A., Hiraga, J. S., ...

Tycho's supernova remnant was observed by the XIS and HXD instruments onboard the Suzaku satellite on 2006 June 26-29 for 92 ks. The spectrum up to 30 keV was well fitted with a two-component model,...

The Suzaku Observation of the Nucleus of the Radio-Loud Active Galaxy Centaurus A: Constraints on Abundances of the Accreting Material (2007)

Markowitz, A., Takahashi, T., Watanabe, S., Nakazawa, K., Fukazawa, Y., Kokubun, M., ...

A Suzaku observation of the nucleus of the radio-loud AGN Centaurus A in 2005 has yielded a broadband spectrum spanning 0.3 to 250 keV. The net exposure times after screening were: 70 ks per X-ray...

Monte-Carlo Simulator and Ancillary Response Generator of Suzaku XRT/XIS System for Spatially Extended Source Analysis (2006)

Ishisaki, Y., Maeda, Y., Fujimoto, R., Ozaki, M., Ebisawa, K., Takahashi, T., ...

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 analysis of spatially...

Chandra Deep X-ray Observation of a Typical Galactic Plane Region and Near-Infrared Identification (2005)

Ebisawa, K., Tsujimoto, M., Paizis, A., Hamaguchi, K., Bamba, A., Cutri, R., ...

Using the Chandra Advanced CCD Imaging Spectrometer Imaging array (ACIS-I), we have carried out a deep hard X-ray observation of the Galactic plane region at (l,b) ~ (28.5, 0.0), where no discrete...

A Chandra Deep X-ray Exposure on the Galactic Plane and Near Infrared Identification (2004)

Ebisawa, K., Paizis, A., Couvoisier, T. J. -L., Dubath, P., Tsujimoto, M., Hamaguchi, K., ...

Using the Chandra ACIS-I instruments, we have carried out a deep X-ray observation on the Galactic plane region at (l,b) ~ (28.5, 0.0), where no discrete X-ray sources have been known previously. We...

Fine Structure of the Thermal and Non-Thermal X-Rays in the SN 1006 Shell (2003)

Bamba, A., Yamazaki, R., Ueno, M., Koyama, K.

The North Eastern shell of SN 1006 is the most probable acceleration site of high energy electrons (up to about 100 TeV) with the Fermi acceleration mechanism at the shock front. We resolved...

Galactic X-ray Survey (2002)

Ebisawa, K., Yamauchi, S., Bamba, A., Ueno, M., Senda, S.

We review highlights of the results obtained from recent Galactic X-ray survey observations, in particular ASCA Galactic center and plane survey and our Chandra deep survey on the (l,b)=(28.5,0)...

Chandra deep X-ray observation on the Galactic plane (2002)

Ebisawa, K., Bamba, A., Kaneda, H., Maeda, Y., Paizis, A., Sato, G., ...

Using the Chandra ACIS-I instruments, we have carried out the deepest X-ray observation on a typical Galactic plane region at l 28.5 deg, where no discrete X-ray sources have been known previously....

X-ray Flare from a Herbig Be star, MWC297 (1999)

Hamaguchi, K., Terada, H., Bamba, A., Koyama, K.

Hard X-ray emissions from a Herbig Be star MWC297 were discovered in three separate observations spanning 5 days in April 1994 with the Advanced Satellite for Cosmology and Astrophysics (ASCA). An...
