  Cosmic strings (CS) are one-dimensional cosmological-size objects predicted
in realistic models of the early Universe. Analysis of the cosmic microwave
background (CMB) anisotropy data from the Wilkinson Microwave Anisotropy Probe
(WMAP) and Planck surveys revealed several CS candidates. One of the
candidates, CSc-1, was found to be most reliable because of the statistically
significant chains of gravitational lensing (GL) candidates in its field. We
observed the brightest of the objects in the CSc-1 field, a galaxy pair
SDSSJ110429.61+233150.3. The significant correlation between the spectra of the
two components indicates the possible GL nature of the pair. Our simulations of
observational data in the CSc-1 field shows that a large number of pairs can be
explained by the complex geometry of the CS. Simulations of the SDSSJ110429
galaxy pair has shown that the observed angle between the components of the
pair can be explained if the CS is strongly inclined and, possibly, bent in the
image plane. In our preliminary data, we also detected the sign of the sharp
isophotal edge in one image, which along with CMB and spectral data strongly
suggests the possibility of a CS detection.
