Discovery of an excess of Halpha emitters around 4C 23.56 at z=2.48

We report on the discovery of a significant excess of candidate Hα emitters (HAEs) in the field of the radio galaxy 4C 23.56 at z = 2.483. Using the MOIRCS near-infrared imager on the Subaru Telescope we found 11 candidate emission-line galaxies to a flux limit of ~7.5 × 10−17 erg s−1 cm−2, which is...
