Abstract

We conducted an exploratory search for quasars at z ∼ 6 − 8, using the Early Data Release from United Kingdom Infrared Deep Sky survey (UKIDSS) cross-matched to panoramic optical imagery. High redshift quasar candidates are chosen using multi-color selection in i, z, Y, J,H and K bands. After removal of apparent instrumental artifacts, our candidate list… (More)
