A new population of X-ray transients in the Galactic Centre
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle +1
A comparison of the XMM-Newton and Chandra Galactic Centre (GC) Surveys has revealed two faint X-ray transients with contrasting properties. The X-ray spectrum of XMM J174544-2913.…
The XMM-Newton view of the Galactic Centre
Masaaki Sakano, Robert S. Warwick, Anne Decourchelle
In X-rays, the Galactic Centre (GC) Region appears as a complex of diffuse thermal and non-thermal X-ray emission intermixed with a population of luminous discrete sources. Here we…
SSC of MAXI experiment
M. Sakano, H. Tomida, M. Matsuoka +16
Monitor of All-sky X-ray Image (MAXI) on the International Space Station (ISS) has two kinds of X-ray detectors: the Gas Slit Camera (GSC) and the Solid-state Slit Camera (SSC). SS…
X-ray source population of the Galactic center region obtained with ASCA
Masaaki Sakano, Katsuji Koyama, Hiroshi Murakami +3
From the ASCA X-ray point-source list in the Galactic center 5x5 degree^2 region, we found the clear correlation between the position of the sources and the absorption. This fact i…
SNRs in the Galactic Center region observed with ASCA
M. Sakano, J. Yokogawa, H. Murakami +3
We report the ASCA results of the supernova remnants (SNRs) and their candidates in the Galactic Center region. We found apparent X-ray emission from G359.1-0.5 and G0.9+0.1, and m…
