Candidate Rotating Toroids around High-Mass (Proto)Stars
R. S. Furuya, R. Cesaroni, S. Takahashi +3
Using the OVRO, Nobeyama, and IRAM mm-arrays, we searched for ``disk''-outflow systems in three high-mass (proto)star forming regions: G16.59-0.05, G23.01-0.41, and G28.87+0.07. Th…
Adaptive Optics Imaging of Lyman Break Galaxies as Progenitors of Spheroids in the Local Universe
M. Akiyama, Y. Minowa, N. Kobayashi +2
In order to reveal the stellar mass distribution of z~3 galaxies, we are conducting deep imaging observations of U-dropout Lyman Break Galaxies (LBGs) with Adaptive Optics (AO) sys…
The Aspherical Properties of the Energetic Type Ic SN 2002ap as Inferred from its Nebular Spectra
P. A. Mazzali, K. S. Kawabata, K. Maeda +10
The nebular spectra of the broad-lined, SN 1998bw-like Type Ic SN 2002ap are studied by means of synthetic spectra. Two different modelling techniques are employed. In one techniqu…
The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- V. Submillimetre properties of near-infrared--selected galaxies in the Subaru/XMM--Newton deep field
T. Takagi, A. M. J. Mortier, K. Shimasaku +21
We have studied the submillimetre (submm) properties of the following classes of near-infrared (NIR)-selected massive galaxies at high redshifts: BzK-selected star-forming galaxies…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
First Steps in Direct Imaging of Planetary Systems Like our Own: The Science Potential of 2-m Class Optical Space Telescopes
Karl Stapelfeldt, John Trauger, Weslay Traub +4
We summarize the scientific potential of high contrast optical space imaging for studies of extrasolar planets, debris disks, and planet formation. The unique scientific capabiliti…
The Reionization and Galaxy Evolution Probed by z=7 Lyman Alpha Emitters
Kazuaki Ota, Masanori Iye, Nobunari Kashikawa +10
We made a narrowband NB973 (bandwidth of 200A at 9755A) imaging of the Subaru Deep Field (SDF) and found two z=7 Lyman alpha emitter (LAE) candidates down to NB973=24.9. Carrying o…
Near-Infrared Coronagraphic Observations of the T Tauri Binary System UY Aur

We present a near-infrared image of UY Aur, a 0.9" separated binary system, using the Coronagraphic Imager with Adaptive Optics on the Subaru Telescope. Thanks to adaptive optics,…
Deep Spectroscopy of Systematically Surveyed Extended Lyman-alpha Sources at z~3-5
Tomoki Saito, Kazuhiro Shimasaku, Sadanori Okamura +4
Spatially extended Ly-alpha sources that are faint and/or compact in coninuum are candidates for extremely young (~< 10^7 yrs) galaxies at high redshifts. We present medium-resolut…
