XMM-Newton peers into the heart of an active galaxy and spots
a supermassive black hole


NGC 6300
NGC 6300 is a nearby active galaxy powered by material accreting onto a supermassive black hole with mass up to 10 billion times the mass of the sun. This galaxy has a ringed, barred, spiral structure and is identified as a bright Seyfert 2 galaxy located in the constellation Altar. The highest energy X-ray emission is coming from the nucleus of the galaxy while the lowest energy X-rays show diffuse emission in the spiral arms. Optical images of NGC 6300 (like HST) show a lot of absorption due to dust in the region of low soft X-ray emission. This image is a composition of the 2-10keV(hard), 1-2keV (medium) and 0.1-1keV (soft) X-ray emission bands.
