NIR spectroscopic observation of massive galaxies in the protocluster at z = 3.09
Mariko Kubo, Toru Yamada, Takashi Ichikawa +3
We present the results of near-infrared spectroscopic observations of the -band selected candidate galaxies in the protocluster at in the SSA22 field. We observed 67 ca…
SEEDS Adaptive Optics Imaging of the Asymmetric Transition Disk Oph IRS 48 in Scattered Light
Katherine B. Follette, Carol A. Grady, Jeremy R. Swearingen +60
We present the first resolved near infrared imagery of the transition disk Oph IRS 48 (WLY 2-48), which was recently observed with ALMA to have a strongly asymmetric sub-millimeter…
Indications of M-dwarf Deficits in the Halo and Thick Disk of the Galaxy
Mihoko Konishi, Hiroshi Shibai, Takahiro Sumi +55
We compared the number of faint stars detected in deep survey fields with the current stellar distribution model of the Galaxy and found that the detected number in the H band is s…
Surface Geometry of Protoplanetary Disks Inferred From Near-Infrared Imaging Polarimetry
Michihiro Takami, Yasuhiro Hasegawa, Takayuki Muto +58
We present a new method of analysis for determining the surface geometry of five protoplanetary disks observed with near-infrared imaging polarimetry using Subaru-HiCIAO. Using as…
A Deep Narrowband Imaging Search for CIV and He II Emission from Ly Blobs
Fabrizio Arrigoni Battaia, Yujin Yang, Joseph F. Hennawi +4
We conduct a deep narrow-band imaging survey of 13 Ly blobs (LABs) located in the SSA22 proto-cluster at z~3.1 in the CIV and HeII emission lines in an effort to constrain the p…
The environments of Ly blobs I: Wide-field Ly imaging of TN J1338-1942, a powerful radio galaxy at associated with a giant Ly nebula
Tomoki Saito, Yuichi Matsuda, Cedric G. Lacey +10
We exploit wide-field Ly imaging with Subaru to probe the environment around TN J1338-1942, a powerful radio galaxy with a >100 kpc Ly halo at z=4.11. We used a sample of…
