Seyfert galaxyNGC 4151Variations in the flux from active galactic nuclei (AGN) allow the testing of models of their emission mechanisms. Various suggestions for the energy generation in AGNs require the existence of a compact object, with X rays generated deep in that object's potential well ...

The Seyfert galaxy NGC4151 observed when the nucleus is at a minimum has two emission lines of full width at half maximum <7 and 16 respectively and varying in intensity by a factor of three in 10 days. These lines are too narrow to be emitted by the whole broad-line region and must ...
