Evidence for a compact source of soft X-rays in the Cygnus loop

  • 1. E. O. Hulburt Center for Space Research, Washington, D.C.

Description

Data obtained in a 3-s observation of the Cygnus Loop (44--60 A) indicate a 21.4 ms periodicity. When the pulsed fraction of 50--60 percent is removed, the residual intensity agrees well with the mean Loop intensity reported by others. The evidence therefore suggests that a compact object is present within the nebula
