Magnetars are a special type of neutron stars, considered to have extreme dipole magnetic fields reaching ~1e+11 T. The magnetar 4U 0142+61, one of prototypes of this class, was studied in broadband X-rays (0.5-70 keV) with the Suzaku observatory. In

Optical, UV and soft x-ray transmission of optical blocking layer for the x-ray CCD

Publikováno v: AIP Conference Proceedings.

We have newly developed the back-illuminated (BI)-CCD which has an Optical Blocking Layer (OBL) directly coating its X-ray illumination surface with Aluminum-Polyimide-Aluminum instead of Optical Blocking Filter (OBF). OBL is composed of a thin polyi

Soft x-ray response of the x-ray CCD camera directly coated with optical blocking layer

Publikováno v: AIP Conference Proceedings.

We have developed the back-illuminated X-ray CCD camera (BI-CCD) to observe Xray in space. The X-ray CCD has a sensitivity not only for in X-ray but also in both Optical and UV light, X-ray CCD has to equip a filter to cut off optical light as well a

We report in-flight status of the X-ray detectors on board the Suzaku observatory, the 5th X-ray astronomy satellite of Japan launched on July 10, 2005. Suzaku is equipped with two types of instruments: one is the X-ray imaging spectrometers (XISs) a

Ages of the magnetar 1E 2259+586 and the associated supernova remnant CTB~109 were studied. Analyzing the Suzaku data of CTB~109, its age was estimated to be $\sim$14~kyr, which is much shorter than the measured characteristic age of 1E 2259+586, 230
