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,…

Implications for Galaxy Evolution from the Cosmic Evolution of Supernova Rate Density

T. Oda, T. Totani, N. Yasuda +4

We report a comprehensive statistical analysis of the observational data of the cosmic evolution of supernova (SN) rate density, to derive constraints on cosmic star formation hist…

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…

Integral Field Spectroscopy of the Quadruply Lensed Quasar 1RXS J1131-1231: New Light on Lens Substructures

H. Sugai, A. Kawai, A. Shimono +5

We have observed the quadruply lensed quasar 1RXS J1131-1231 with the integral field spectrograph mode of the Kyoto Tridimensional Spectrograph II mounted on the Subaru telescope.…

Afterglow spectrum of a gamma-ray burst with the highest known redshift z=6.295

N. Kawai, G. Kosugi, K. Aoki +25

Gamma-ray bursts (GRBs) and their afterglows have been proposed as an excellent probe to study the evolution of cosmic star formation, the reionization of the intergalactic medium,…

Implications for the Cosmic Reionization from the Optical Afterglow Spectrum of the Gamma-Ray Burst 050904 at z = 6.3

Tomonori Totani, Nobuyuki Kawai, George Kosugi +5

The gamma-ray burst (GRB) 050904 at z = 6.3 provides the first opportunity of probing the intergalactic medium (IGM) by GRBs at the epoch of the reionization. Here we present a spe…
