BLACK HOLES. “This AGN cosmic downsizing trend is seen across a wide range of the electromagnetic spectrum in X-ray, optical, infrared, and radio wavebands. If AGN luminosity would strictly correlate with black hole mass, this finding would imply that more massive black holes formed before lower-mass black holes, which is in apparent contradiction to the currently favored hierarchical structure formation paradigm based on the standard cold dark matter model.” (AGN = active galactic nuclei).
