- Title
Contribution of strings to the observed variability of extragalactic sources of radiation.
- Authors
Ossipov, D. L.
- Abstract
The mechanism for the fast variability introduced in the observed luminosity of compact extragalactic sources of radiation by the diffraction of electromagnetic radiation by cosmic strings is studied. Cosmic strings at cosmological distances can produce not only the observed variability but also a large increase in the observed luminosity of quasars. Curves of the variation of the luminosity are obtained and the characteristic times of the oscillations of the luminosity are presented for a string with density 1016 g/cm. © 1996 American Institute of Physics.
