Abstract: (arXiv)
We present the 2.12~μ\mum 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\alpha or [O~{\sc 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~{\sc iii}] emission-line objects. The remaining one target shows no Hα\alpha emission in spite of its bright rest-UV luminosity, indicating that this object is already under the post-starburst phase. The volume-averaged SFRSFR derived from the detected two Hα\alpha emission is roughly consistent with that evaluated from the rest-UV continuum.
