The amount of dispersion in these objects is related to the quantity of free electrons between them and earth, providing information about the warm ionized medium. The central object of the Crab nebula is one of these. Thomas Gold was the first to correctly classify these objects, which were dubbed "LGMs" by Hewish and Bell, who thought they were signals from extraterrestrials. The "lighthouse model" describes, for 10 points, these rapidly rotating neutron stars named for their periodically emitted radiation.
