A First Light
The images above left are the first light images of the four X-ray Imaging Spectrometers (XIS0-4) on the Suzaku X-ray observatory. The images are of a supernova remnant E0102-72.3 in the Small Magellanic Cloud. Along with imaging capability, the XIS detectors also provide spectral capability using "front-side illuminated" (FI) and "back-side illuminated" (BI) detectors. The BI detectors in particular have better sensitivity to low-energy X-ray photons, as seen in the lower right image, where emission lines (as encircled by the blue line) from OVII (oxygen which has lost 6 electrons) and OVIII (oxygen which has lost 7 electrons) at about 500 eV are separated.
