Nobeyama Millimeter Array Observations of the Nuclear Starburst of M 83: A GMA Scale Correlation between Dense Gas Fraction and Star Formation Efficiency

Kohno, Kotaro; Kuno, Nario; Nakanishi, Kouichiro +6 more

We present aperture synthesis high-resolution (∼7'' × 3'') observations in CO (J = 1--0), HCN (J = 1--0), and 95GHz continuum emission toward the central (∼1.5 kpc) region of the nearby barred spiral galaxy M 83 with the Nobeyama Millimeter Array. Our high-resolution CO (J = 1--0) mosaic map depicts the presence of molecular ridges along the leadi…

High-Resolution Near-Infrared Images of the T Tauri Binary System XZ Tauri

Pyo, Tae-Soo; Tamura, Motohide; Hayashi, Masahiko +8 more

We present a high-resolution (∼0.1'' = 14AU) H-band image of XZ Tau, a 0.3''-separated classical T Tauri binary system, taken with the Coronagraphic Imager with Adaptive Optics (CIAO) on the Subaru Telescope. We found a scattered light nebula extending to ∼2.4'' from the secondary, XZ Tau S, in the northeast region of the binary. Its surface brigh…

A Massive Disk Galaxy at z > 3 along the Line of Sight of QSO 1508+5714

Tanaka, Ichi; Yamada, Toru; Iye, Masanori +1 more

We have obtained deep images in the BVRIJHKs bands of the field centered on QSO 1508+5714 5714 (Z_em = 4.28) with the Suprime-Cam, FOCAS, and MOIRCS cameras on Subaru telescope. We report here on the detection of a B-dropout galaxy, which is 3.5'' north-west of the QSO sightline. A photometric redshift analysis is presented to complement…
