A metric space for type Ia supernova spectra
Michele Sasdelli, W. Hillebrandt, G. Aldering +43
We develop a new framework for use in exploring Type Ia Supernova (SN Ia) spectra. Combining Principal Component Analysis (PCA) and Partial Least Square analysis (PLS) we are able…
Type Ia supernova bolometric light curves and ejected mass estimates from the Nearby Supernova Factory
R. Scalzo, G. Aldering, P. Antilogus +32
We present a sample of normal type Ia supernovae from the Nearby Supernova Factory dataset with spectrophotometry at sufficiently late phases to estimate the ejected mass using the…
Type Ia Supernova Hubble Residuals and Host-Galaxy Properties
A. G. Kim, G. Aldering, P. Antilogus +33
Kim et al. (2013) [K13] introduced a new methodology for determining peak-brightness absolute magnitudes of type Ia supernovae from multi-band light curves. We examine the relation…
Improved cosmological constraints from a joint analysis of the SDSS-II and SNLS supernova samples
M. Betoule, R. Kessler, J. Guy +60
We present cosmological constraints from a joint analysis of type Ia supernova (SN Ia) observations obtained by the SDSS-II and SNLS collaborations. The data set includes several l…
Two superluminous supernovae from the early universe discovered by the Supernova Legacy Survey
D. A. Howell, D. Kasen, C. Lidman +14
We present spectra and lightcurves of SNLS 06D4eu and SNLS 07D2bv, two hydrogen-free superluminous supernovae discovered by the Supernova Legacy Survey. At z = 1.588, SNLS 06D4eu i…
Photometry of supernovae in an image series : methods and application to the Supernova Legacy Survey (SNLS)
P. Astier, P. El Hage, J. Guy +6
We present a technique to measure lightcurves of time-variable point sources on a spatially structured background from imaging data. The technique was developed to measure light cu…
