Panoramic H-alpha and mid-infrared mapping of star formation in a z=0.8 cluster
Yusei Koyama, Tadayuki Kodama, Kazuhiro Shimasaku +4
We present the first wide-field H-alpha imaging survey around the distant cluster RXJ1716.4+6708 at z=0.81 with a narrow-band filter on MOIRCS/Subaru, down to SFR(Ha)~1Msun/yr. Com…
High star formation activity in the central region of a distant cluster at z=1.46
Masao Hayashi, Tadayuki Kodama, Yusei Koyama +3
We present an unbiased deep [OII] emission survey of a cluster XMMXCS J2215.9-1738 at z=1.46, the most distant cluster to date with a detection of extended X-ray emission. With wid…
The spectroscopically confirmed huge cosmic structure at z=0.55
M. Tanaka, A. Finoguenov, T. Kodama +3
We report on the spectroscopic confirmation of a huge cosmic structure around the CL0016 cluster at z=0.55. We made wide-field imaging observations of the surrounding regions of th…
