Suzaku Observation of AXP 1E 1841-045 in SNR Kes 73 (2007)
Morii, M., Kitamoto, S., Shibazaki, N., Takei, D., Kawai, N., Arimoto, M., ...
Anomalous X-ray pulsars (AXPs) are thought to be magnetars, which are neutron stars with ultra strong magnetic field of $10^{14}$-- $10^{15}$ G. Their energy spectra below $\sim$10 keV are modeled...
Broad band X-ray spectroscopy of A0535+262 with SUZAKU (2007)
Naik, S., Dotani, T., Terada, Y., Nakajima, M., Mihara, T., Suzuki, M., ...
The transient X-ray binary pulsar A0535+262 was observed with Suzaku on 2005 September 14 when the source was in the declining phase of the August-September minor outburst. The ~103 s X-ray pulse...
Detection of a Rare Supersoft Outburst Event during a Suzaku Observation of 1E0102.2-7219 (2007)
Takei, D., Tsujimoto, M., Kitamoto, S., Morii, M., Ebisawa, K., Maeda, Y., ...
We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was detected at the...
Cyclotron resonance energies at a low X-ray luminosity: A0535+262 observed with Suzaku (2006)
Terada, Y., Mihara, T., Nakajima, M., Suzuki, M., Isobe, N., Makishima, K., ...
The binary X-ray pulsar A0535+262 was observed with the Suzaku X-ray observatory, on 2005 September 14 for a net exposure of 22 ksec. The source was in a declining phase of a minor outburst,...
Wide band X-ray Imager (WXI) and Soft Gamma-ray Detector (SGD) for the NeXT Mission (2004)
Takahashi, T., Awaki, A., Dotani, T., Fukazawa, Y., Hayashida, K., Kamae, T., ...
The NeXT mission has been proposed to study high-energy non-thermal phenomena in the universe. The high-energy response of the super mirror will enable us to perform the first sensitive imaging...
Energy Spectra and Normalized Power Spectral Densities of X-Ray Nova GS 2000+25 (2002)
Terada, K., Kitamoto, S., Negoro, H., Iga, S.
The X-ray energy spectra and Normalized Power Spectral Densities (NPSDs) of an X-ray nova, GS 2000+25, were investigated. The X-ray energy spectra of the source consist of two components: a hard...
Long-term X-ray variability and state transition of GX 339-4 (2001)
Kong, A. K. H., Charles, P. A., Kuulkers, E., Kitamoto, S.
With extensive monitoring data spanning over 30 years from Vela 5B, Ariel 5, Ginga, Compton Gamma Ray Observatory, Rossi X-ray Timing Explorer and BeppoSAX, we find evidence for long-term X-ray...
Changes in the long term intensity variations in Cyg X-2 and LMC X-3 (2000)
Paul, B., Kitamoto, S., Makino, F.
We report the detection of changes in the long-term intensity variations in two X-ray binaries, Cyg X-2 and LMC X-3. In this work, we have used the long-term light curves obtained with the All-Sky...
MAXI mission for the space station (1999)

Complex outburst behaviour from the black-hole candidate 4U 1630-47 (1997)
Kuulkers, E., Parmar, A. N., Kitamoto, S., Cominsky, L. R., Sood, R. K.
We present data from different epochs in 1978, 1987-1991 and 1996 from the black-hole candidate 4U1630-47. For the first time we present almost complete coverage of the outbursts which started in...
