From a sample of supermassive black holes, astronomers have found that the growth of a supermassive black hole is strongly related to galaxy formation.
The next generation of X-ray telescopes should provide evidence of the rotational nature of supermassive black holes.
A new report from the National Research Council of the National Acadamies provides priorities for how astronomy research funding should be spend in the next decade.
The Chandra X-ray Observatory has resolved the sources contributing to the X-ray background. The results show that nearly a third of the sources are active galactic nuclei and another third is composed of "ultra-faint galaxies."
