Three-Dimensional Explosion Geometry of Stripped-Envelope Core-Collapse Supernovae. I. Spectropolarimetric Observations
Masaomi Tanaka, Koji S. Kawabata, Takashi Hattori +8
We study the multi-dimensional geometry of supernova (SN) explosions by means of spectropolarimetric observations of stripped-envelope SNe, i.e., SNe without a H-rich layer. We per…
Spectropolarimetry of Extremely Luminous Type Ia Supernova 2009dc: Nearly Spherical Explosion of Super-Chandrasekhar Mass White Dwarf
Masaomi Tanaka, Koji S. Kawabata, Masayuki Yamanaka +8
We present the first spectropolarimetric observations of a candidate of super-Chandrasekhar mass Type Ia supernova (SN): SN 2009dc. The observations were performed at 5.6 and 89.5…
The Subaru/XMM-Newton Deep Survey (SXDS) - II. Optical Imaging and Photometric Catalogs
H. Furusawa, G. Kosugi, M. Akiyama +33
We present multi-waveband optical imaging data obtained from observations of the Subaru/XMM-Newton Deep Survey (SXDS). The survey field, centered at R.A.=02:18:00, decl.=-05:00:00,…
Asphericity in Supernova Explosions from Late-Time Spectroscopy
Keiichi Maeda, Koji Kawabata, Paolo A. Mazzali +15
Core-collapse supernovae (CC-SNe) are the explosions that announce the death of massive stars. Some CC-SNe are linked to long-duration gamma-ray bursts (GRBs) and are highly aspher…
Luminosity Functions of Lyman-Break Galaxies at z~4 and 5 in the Subaru Deep Field
Makiko Yoshida, Kazuhiro Shimasaku, Nobunari Kashikawa +3
We investigate the luminosity functions of Lyman-break galaxies (LBG) at z~4 and 5 based on the optical imaging data obtained in the Subaru Deep Field Project. Three samples of LBG…
The End of the Reionization Epoch Probed by Ly-alpha Emitters at z=6.5 in the Subaru Deep Field
N. Kashikawa, K. Shimasaku, M. A. Malkan +16
We report an extensive search for Lyman-alpha emitters (LAEs) at z=6.5 in the Subaru Deep Field. Subsequent spectroscopy with Subaru and Keck identified eight more LAEs, giving a t…
