Abstract

We search the COSMOS survey for pairs of galaxies consistent with the gravitational lensing signature of a cosmic string. The COSMOS survey imaged 1.64 square degrees using the Advanced Camera for Surveys aboard the Hubble Space Telescope. Our technique includes estimates of the efficiency for finding the lensed galaxy pair. We find no evidence for cosmic strings with a mass per unit length of $G μ / c^{2} < 3.0 \times 10^{- 7}$ out to redshifts greater than 0.6 and set 95% upper limits. This corresponds to a global 95% upper limit of $Ω_{strings} < 0.0028$ .
