我们展示了用 Subaru 望远镜上的近红外相机 (CISCO) 拍摄的哈勃深空北区 2.12 yum 窄带图像。在 Ha 或 [O III] 发射线红移到我们根据其光谱红移预期的窄带范围的五个目标中，其中四个具有强发射线，特别是对于两个 [O III] 发射线天体。剩下的一个目标尽管具有明亮的剩余紫外光度，但没有显示出 Ha 发射，这表明该物体已经处于后星暴阶段。从检测到的两 Ha 发射得出的体积平均恒星形成率与从剩余紫外连续谱评估的体积平均恒星形成率大致一致。
We present the 2.12 yum narrow-band image of the Hubble Deep Field North taken with the nearinfrared camera (CISCO) on the Subaru telescope. Among five targets whose Ha 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 Ha 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 Ha emission is roughly consistent with that evaluated from the rest-UV continuum.
