Near-infrared emission-line galaxies in the Hubble Deep Field North
arXiv:astro-ph/0001050 · doi:10.1093/pasj/52.1.73
Abstract
We present the 2.12~$μ$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 H$α$ 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 H$α$ 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 H$α$ emission is roughly consistent with that evaluated from the rest-UV continuum.
