MOIRCS Deep Survey. IX. Deep Near-Infrared Imaging Data and Source Catalog
Ouchi, Masami; Tanaka, Ichi; Yamada, Toru +13 more
We present deep J-, H-, and Ks-band imaging data of the MOIRCS Deep Survey (MODS), which was carried out with the Multi-Object Infrared Camera and Spectrograph (MOIRCS) mounted on the Subaru Telescope in the GOODS-North region. The data reach 5σ total limiting magnitudes for point sources of J = 23.9, H = 22.8, and Ks = 22.8 …
Diffraction-Limited Subaru Imaging of M82: Sharp Mid-Infrared View of the Starburst Core
Isobe, Naoki; Gandhi, Poshak; Sakon, Itsuki +4 more
We present new imaging at 12.81 and 11.7 µm of the central ∼ 40''× 30'' (∼ 0.7 kpc × 0.5 kpc) of the starburst galaxy M 82. The observations were carried out with the COMICS mid-infrared (mid-IR) imager on the 8.2 m Subaru Telescope, and are diffraction-limited at an angular resolution of <0''.4. The images show extensive diffuse structur…
MOIRCS Deep Survey. X. Evolution of Quiescent Galaxies as a Function of Stellar Mass at 0.5 < z < 2.5
Tanaka, Ichi; Yamada, Toru; Kajisawa, Masaru +4 more
We studied the evolution of quiescent galaxies at 0.5 < z < 2.5 as a function of the stellar mass, using very deep NIR imaging data from the MOIRCS Deep Survey in the GOODS-North region. The deep NIR data allowed us to construct a stellar mass-limited sample of quiescent galaxies down to ∼1010Modot, even at z ∼ 2, for t…
High-Resolution Optical and Near-Infrared Images of the FS Tauri Circumbinary Disk
Hayashi, Masahiko; Fukagawa, Misato; Itoh, Yoichi +2 more
We present an H-band image of FS Tauri, a 0.''2-separated classical T Tauri binary system, taken with the Coronagraphic Imager with Adaptive Optics (CIAO) on the Subaru Telescope. This new image, combined with Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) F606W-band polarimetric images, shows that the binary has complicated circumbi…
Cryogenic Volume-Phase Holographic Grisms for MOIRCS
Shimasaku, Kazuhiro; Tanaka, Ichi; Yamada, Toru +12 more
We have developed high-dispersion VPH (volume phase holographic) grisms with zinc selenide (ZnSe) prisms for the cryogenic optical system of MOIRCS (Multi-Object near-InfraRed Camera and Spectrograph) for Y-, J-, H-, and K-band observations. We fabricated VPH gratings using a hologram resin. After several heat cycles at between room temperature an…
MOIRCS Deep Survey. VII. NIR Morphologies of Star-Forming Galaxies at Redshift z 1
Ouchi, Masami; Tanaka, Ichi; Yamada, Toru +11 more
We investigated rest-frame near-infrared (NIR) morphologies of a sample of 139 galaxies with
