Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112

M. Oguri, N. Inada, C. R. Keeton +25

We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62…

A Gravitationally Lensed Quasar with Quadruple Images Separated by 14.62 Arcseconds

N. Inada, M. Oguri, B. Pindor +29

Gravitational lensing is a powerful tool for the study of the distribution of dark matter in the Universe. The cold-dark-matter model of the formation of large-scale structures pre…
