Time Dilation in Type Ia Supernova Spectra at High Redshift
S. Blondin, T. M. Davis, K. Krisciunas +29
We present multiepoch spectra of 13 high-redshift Type Ia supernovae (SNe Ia) drawn from the literature, the ESSENCE and SNLS projects, and our own separate dedicated program on th…
Towards More Precise Survey Photometry for PanSTARRS and LSST: Measuring Directly the Optical Transmission Spectrum of the Atmosphere
Christopher W. Stubbs, F. William High, Matthew R. George +7
Motivated by the recognition that variation in the optical transmission of the atmosphere is probably the main limitation to the precision of ground-based CCD measurements of celes…
Observational Constraints on the Nature of the Dark Energy: First Cosmological Results from the ESSENCE Supernova Survey
W. M. Wood-Vasey, G. Miknaitis, C. W. Stubbs +34
We present constraints on the dark energy equation-of-state parameter, w=P/(rho c^2), using 60 Type Ia supernovae (SNe Ia) from the ESSENCE supernova survey. We derive a set of con…
Determining the Type, Redshift, and Phase of a Supernova Spectrum
Stéphane Blondin, John L. Tonry
We present an algorithm to identify the types of supernova spectra, and determine their redshift and phase. This algorithm, based on the correlation techniques of Tonry & Davis, is…
Extracting clean supernova spectra
S. Blondin, J. R. Walsh, B. Leibundgut +1
We use a new technique to extract the spectrum of a supernova from that of the contaminating background of its host galaxy, and apply it to the specific case of high-redshift Type…
