Subaru FOCAS Spectroscopic Observations of High-Redshift Supernovae (2009)

Morokuma, Tomoki, Tokita, Kouichi, Lidman, Christopher, Doi, Mamoru, Yasuda, Naoki, Aldering, Greg, ...

We present spectra of high-redshift supernovae (SNe) that were taken with the Subaru low resolution optical spectrograph, FOCAS. These SNe were found in SN surveys with Suprime-Cam on Subaru, the...

First-year Sloan Digital Sky Survey-II (SDSS-II) Supernova Results: Hubble Diagram and Cosmological Parameters (2009)

Kessler, Richard, Becker, Andrew, Cinabro, David, Vanderplas, Jake, Frieman, Joshua A., Marriner, John, ...

We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 < z < 0.42, discovered during the first season (Fall 2005) of the Sloan Digital Sky Survey-II...

The Sloan Digital Sky Survey-II: Photometry and Supernova Ia Light Curves from the 2005 data (2009)

Holtzman, Jon A., Marriner, John, Kessler, Richard, Sako, Masao, Dilday, Ben, Frieman, Joshua A., ...

We present ugriz light curves for 146 spectroscopically confirmed or spectroscopically probable Type Ia supernovae from the 2005 season of the SDSS-II Supernova survey. The light curves have been...

Early Spectral Evolution of the Rapidly Expanding Type Ia SN 2006X (2009)

Yamanaka, Masayuki, Naito, Hiroyuki, Kinugasa, Kenzo, Takanashi, Naohiro, Tanaka, Masaomi, Kawabata, Koji S., ...

We present optical spectroscopic and photometric observations of Type Ia supernova (SN) 2006X from --10 to +91 days after the $B$-band maximum. This SN exhibits one of the highest expansion velocity...

Science with UT's Dichroic-Mirror Camera (DMC), 15-band simultaneous imager (2008)

Kuncarayakti, Hanindyo, Doi, Mamoru, Malasan, Hakim L., Hayano, Junji, Utsunomiya, Hiroyuki, Ihara, Yutaka, ...

We introduce the Dichroic-Mirror Camera (DMC), an instrument developed at the University of Tokyo which is capable of performing simultaneous imaging in fifteen bands. The main feature of the DMC is...

First-Year Spectroscopy for the SDSS-II Supernova Survey (2008)

Zheng, Chen, Romani, Roger W., Sako, Masao, Marriner, John, Bassett, Bruce, Becker, Andrew, ...

This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of...
