JUDO2 Samples

A page displayed with JUDO2 is "static", in the sense that the page has a fixed URL (permalink). To display the fixed URL, click the "permalink" of "Links" icon in the side menu. Here, we show several sample permalinks which demonstrate effective usages of JUDO2.

Compare instruments with different spatial resolutions

• MAXI and Swift-BAT images of the Galactic plane.
• Suzaku and XMM-Newton images of Eta Carinae

Compare observations with different wavelengths

• Vela-Carena region MAX GSC (hard X-rays) and SSC (Soft X-ray) images
• Suzaku (X-ray) and Akari (Far infrared) images of Cygnus loop
• The Horse-head Nebula in optical (DSS) and Far infrared (Akari).　
  The nebular is very dark in optical, whereas very bright in far-infrared.

Evolution of variable X-ray sources

• An X-ray flare of X1724-308(MAXI GSC) on 2009/8/20
  Confirm that the source was bright only on August 20, 2009 by forwarding or reversing the MAXI GSC daily images.
• Hard state to Soft state transition of the black hole candidate XTE J1752-223 (MAXI GSC) around January 21, 2010
  Forward the daily images to see that the source color changes from bluish (hard X-ray spectrum) on January 19, 2010 to reddish (soft X-ray spectrum) on January 27, 2010.

Constellations

• You can easily see which constellation you are looking at.
  The background image is by MAXI GSC.
• Coma cluster region with MAXI SSC image (background) and Suzaku footprints (pink).
  Suzaku carried out a sequence of offset pointings to cover outskirts of several largely extended clusters of galaxies. In this picture, Coma ("hair of the head") cluster is seen.
• You can see how stars are connected to make constellations.
  What does this look like? The answer is here.
