Multi-image x-ray interferometer module: II. Demonstration of high-resolution x-ray imaging with regular-interval coded apertures

Kazunori Asakura, Kiyoshi Hayashida, Tomokage Yoneyama +5

We have been developing an x-ray imaging system, Multi-Image X-ray Interferometer Module (MIXIM), to achieve a high angular resolution with a compact system size. MIXIM is comprise…

X-ray spectroscopy of the accretion disk corona source 2S 0921-630 with Suzaku archival data

Tomokage Yoneyama, Tadayasu Dotani

2S 0921630 is an eclipsing low-mass X-ray binary (LMXB) with an orbital period of 9 days. Past X-ray observations have revealed that 2S 0921630 has an extended accreti…

Suzaku Detection of Solar Wind Charge Exchange Emission from a Variety of Highly-ionized Ions in an Interplanetary Coronal Mass Ejection

Kazunori Asakura, Hironori Matsumoto, Koki Okazaki +8

X-ray emission generated through solar-wind charge exchange (SWCX) is known to contaminate X-ray observation data, the amount of which is often significant or even dominant, partic…

Experimental studies on the charge transfer inefficiency of CCD developed for the soft X-ray imaging telescope Xtend aboard the XRISM satellite

Yoshiaki Kanemaru, Jin Sato, Toshiyuki Takaki +38

We present experimental studies on the charge transfer inefficiency (CTI) of charge-coupled device (CCD) developed for the soft X-ray imaging telescope, Xtend, aboard the XRISM sat…

Discovery of a transient X-ray source Suzaku J1305-4930 in NGC 4945

Shuntaro Ide, Kiyoshi Hayashida, Hirofumi Noda +3

We report the serendipitous discovery of a transient X-ray source, Suzaku J13054930, 3 kpc southwest of the nucleus of the Seyfert 2 galaxy NGC 4945. Among the seven Suzak…
