J.; Okamura, Sadanori; Hayashi, Masao; Cirasuolo, Michele; Dressler, Alan; Iye, Masanori; Jarvis, M.J.; Kodama, Tadayuki; Martin, Crystal L.; McLure, Ross J.; Ohta, Kouji; Yamada, Toru; Yoshida, Michitoshi (2009-05-10)
      We report the discovery of a giant Lyα emitter (LAE) with a Spitzer/Infrared Array Camera (IRAC) counterpart near the reionization epoch at z = 6.595. The giant LAE is found from the extensive 1 deg2 Subaru narrowband ...

(2010)
      Fibre Multi-Object Spectrograph (FMOS) is the first near-infrared instrument with a wide field of view capable of acquiring spectra simultaneously from up to 400 objects. It has been developed as a common-use instrument ...

    • The mass-metallicity relation at z 1.4 revealed with Subaru/FMOS 

      Yabe, Kiyoto; Ohta, Kouji; Iwamuro, Fumihide; Akiyama, Masayuki; Tamura, Naoyuki; Yuma, Suraphong; Kimura, Masahiko; Takato, Naruhisa; Moritani, Yuki; Sumiyoshi, Masanao; Maihara, Toshinori; Silverman, John; Dalton, Gavin; Lewis, Ian; Bonfield, D.; Lee, Hanshin; Curtis-Lake, Emma; Macaulay, Edward; Clarke, Fraser (2014-02-01)
      We present a stellar mass-metallicity relation at z ~ 1.4 with an unprecedentedly large sample of ~340 star-forming galaxies obtained with FibreMulti-Object Spectrograph (FMOS) on the Subaru Telescope. We observed K-band ...

    • NIR spectroscopy of star-forming galaxies at z similar to 1.4 with Subaru/FMOS : The mass-metallicity relation. 

      Yabe, Kiyoto; Ohta, Kouji; Iwamuro, Fumihide; Yuma, Suraphong; Akiyama, Masayuki; Tamura, Naoyuki; Kimura, Masahiko; Takato, Naruhisa; Moritani, Yuuki; Sumiyoshi, Masanao; Maihara, Toshinori; Silverman, John; Dalton, Gavin; Lewis, Ian; Bonfield, David; Lee, Hanshin; Lake, Emma Curtis; Macaulay, Edward; Clarke, Fraser (2012-06-25)
      We present near-infrared spectroscopic observations of star-forming galaxies at z similar to 1.4 with FMOS on the Subaru Telescope. We observed K-band selected galaxies in the SXDS/UDS fields with K <= 23.9 mag, 1.2 <= ...
