Cosmic Strings Revisited

This high energy consideration does this, as well as directs the mind to consider the cosmological evidence that lays before us now. Dimensional interpretation, has to have it's basis contained within this whole view. With the cosmic string we are only defining a period of time with in the whole expression of this same universe? This would inlcude Pre bang scenarios and how these must be included.

Cosmic Superstrings Revisitedby Joseph Polchinski

Thus far we have quoted upper bounds, but there are possible detections of strings via gravitational lensing. A long string will produce a pair of images symmetric about an axis, very different from lensing by a point mass. Such an event has been reported recently

Lens candidates in the Capodimonte Deep Field in vicinity of the CSL1 object by Sazhin M.V.1, Khovanskaya O.S.1, Capaccioli M.2,3, Longo G.3,4,Alcal´a J.M. 2, Silvotti R.2, Pavlov M.V.2

In Paper I we discussed the strange properties of CSL1: a peculiar object discovered in the OACDF which spectroscopic investigations proveed to be the double undistorted image of an elliptical galaxy. Always in Paper I we showed that CSL1 could be interpreted as the first case of lensing by a cosmic string.

In the present work, starting from consideration that a cosmic string is an elongated
structure which produces non local effects we investigated the statistics of lens candidates around the CSL1 position.
