Imaging of SDSS z > 6 quasar fields: Gravitational lensing, companion galaxies, and the host dark matter halos

We have undertaken deep optical imaging observations of three 6.2 < z < 6.5 quasar fields in the i′ and z′ filters. These data are used to search for foreground galaxies that are gravitationally lensing the quasars and distant galaxies physically associated with the quasars. Foreground...
