The North Galactic Pole in the ROSAT All-Sky Survey
The image shows the about 17 × 17 square degrees clipping from the region of the Galactic North Pole taken from the sky map of the ROSAT PSPC All-Sky Survey. The bright extended object near the North Pole is the Coma galaxy cluster; part of the North Polar Spur is seen in the lower right corner. The soft X-ray exposure (0.1 - 0.4 keV) is superposed by 100 µm contour lines of the Leiden Dwingeloo Survey of neutral hydrogen. The correlation of the reduced X-ray intensity (blue, violet) in the regions of increased hydrogen column density is clearly seen. The interstellar matter shadows the X-ray emission behind it and basically only the X-ray emission from the foreground is seen. From this, conclusions can be drawn for the emission distribution along the line of sight.
