Adaptive optics imaging search for damped Lyα absorbers toward APM 08279+5255

We present initial results from an high-resolution imaging search for damped Lyα absorbers toward the high-redshift quasar apm 08279+5255 by using the adaptive optics system (ao) attached to the subaru telescope. We detected in total 11 objects within a 23''×23'' field around the quasar. Among these detected objects, we identified a possible candidate for the galaxy giving rise to the damped Lyα absorption at z_abs=2.974 with a criteria of distance from the sight-line toward the quasar and luminosity.
