Near-Infrared Emission-Line Galaxies in the Hubble Deep Field North
Abstract
We present the 2.12 mu m narrow-band image of the Hubble Deep Field North taken with the near-infrared camera (CISCO) on the Subaru telescope. Among five targets whose Hα or [O III] emission lines are redshifted into our narrow-band range expected from their spectroscopic redshift, four of them have strong emission lines, especially for the two [O III] emission-line objects. The remaining one target shows no Hα emission in spite of its bright rest-UV luminosity, indicating that this object is already under the post-starburst phase. The volume-averaged SFR derived from the detected two Hα emission is roughly consistent with that evaluated from the rest-UV continuum.
