A gravitational lensed quasar with quadruple images separated by 14.62 arcseconds
Article Abstract:
The existence of the cold-dark matter model of the formation of large-scale structures shows the existence of the quasars gravitationally lensed by contractions of dark matter. The discovery of a lensed quasar, SDSS J1004+4112, with a maximum separation between the components of 14.62 arcsec is described.

The central image of a gravitationally lensed quasar
Article Abstract:
