We examine a sample of 2301 gamma-ray bursts, detected by Konus-Wind in the triggered mode between 1994 and 2017 and localized by the interplanetary network(IPN), for evidence of gravitational lensing. We utilize all the available gamma-ray burst(GRB) data : time histories, localizations, and energy spectra. We employ common IPN techniques to find and quantify similarities in the light curves of 2, 646, 150 burst pairs, and for the pairs with significant similarities, we examine their IPN localizations to determine whether they are consistent with a common origin.

Les Français ont fourni des instruments composés de détecteurs gamma à scintillation aux Russes qui s'occupaient quant à eux de la plateforme 1 du satellite. En 1977, fut lancé l'instrument Signe 2 à bord de la mission russe Prognoz 6, en orbite autour de la Terre. Par la suite, le même instrument fut lancé à bord de deux satellites jumeaux appelés Prognoz 7, constituant deux membres du réseau interplanétaire.

Subject field(s)
  • Astronautics
CONT

The detection of an echo of a gamma-ray burst(GRB) caused by gravitational lensing is the only means of directly confirming the cosmological nature of bursts. The echo should appear within the same positional error box on the sky as the original burst, but will occur at a later time.

PHR

Positional error box of gamma-ray source.

  • Astronautique
