Despite the enormous changes in the space density of back holes, the individual engines powering active galactic nuclei are remarkably stable.

Once again the mastermind was Lionel Curtis, and the earlier Round Table Groups and Institutes of International Affairs were used as nuclei for the new network.
We would like to know if active galactic nuclei change over cosmic time. Do black holes feed and grow in the same way over the history of the Universe
In the firm expectation that when London shall be a habitation of bitterns, when St. Paul and Westminster Abbey shall stand shapeless and nameless ruins in the midst of an unpeopled marsh, when the piers of Waterloo Bridge shall become the nuclei of islets of reeds and osiers, and cast the jagged shadows of their broken arches on the solitary stream, some Transatlantic commentator will be weighing in the scales of some new and now unimagined system of criticism the respective merits of the Bells and the Fudges and their historians.
The research included neutron resonance spectroscopy, the angular distribution of pion elastic and inelastic scattering on nuclei with optical model fitting.
The doctors realized in retrospect that even though most of these dead had also suffered from burns and blast effects, they had absorbed enough radiation to kill them. The rays simply destroyed body cells - caused their nuclei to degenerate and broke their walls.
I was interested in nuclei originally with my deuteron photo work because that was one of the fundamental forces, and the measurement was basic to new science.
Direction coupling between the various radiations generated in a nuclear reaction both with one another and with the initiating radiation can also be detected and measured by coincidences; this provides valuable information about the structure of the atomic nuclei.
