Science with UT's Dichroic-Mirror Camera (DMC), 15-band simultaneous imager
Hanindyo Kuncarayakti, Mamoru Doi, Hakim L. Malasan +20
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 fea…
Discovery of an Unusual Optical Transient with the Hubble Space Telescope
K. Barbary, K. S. Dawson, K. Tokita +27
We present observations of SCP 06F6, an unusual optical transient discovered during the Hubble Space Telescope Cluster Supernova Survey. The transient brightened over a period of ~…
Light curve studies of nearby Type Ia Supernovae with a Multi-band Stretch method
N. Takanashi, M. Doi, N. Yasuda
We create new U, B, V, R and I-band light curve templates of type Ia Supernovae (SNe Ia) and re-analyze 122 nearby (redshift < 0.11) SNe Ia using a new ``Multi-band Stretch method,…
First-Year Spectroscopy for the SDSS-II Supernova Survey
Chen Zheng, Roger W. Romani, Masao Sako +77
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…
A Measurement of the Rate of type-Ia Supernovae at Redshift 0.1 from the First Season of the SDSS-II Supernova Survey
Benjamin Dilday, R. Kessler, J. A. Frieman +50
We present a measurement of the rate of type Ia supernovae (SNe Ia) from the first of three seasons of data from the SDSS-II Supernova Survey. For this measurement, we include 17 S…
The Sloan Digital Sky Survey-II Supernova Survey: Search Algorithm and Follow-up Observations
Masao Sako, B. Bassett, A. Becker +47
The Sloan Digital Sky Survey-II Supernova Survey has identified a large number of new transient sources in a 300 sq. deg. region along the celestial equator during its first two se…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
Rest-Frame R-band Lightcurve of a z~1.3 Supernova Obtained with Keck Laser Adaptive Optics
J. Melbourne, K. S. Dawson, D. C. Koo +24
We present Keck diffraction limited H-band photometry of a z~1.3 Type Ia supernova (SN) candidate, first identified in a Hubble Space Telescope (HST) search for SNe in massive high…
