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…
Host Galaxy Properties and Hubble Residuals of Type Ia Supernovae from the Nearby Supernova Factory
M. J. Childress, G. Aldering, P. Antilogus +32
We examine the relationship between Type Ia Supernova (SN Ia) Hubble residuals and the properties of their host galaxies using a sample of 115 SNe Ia from the Nearby Supernova Fact…
Host Galaxies of Type Ia Supernovae from the Nearby Supernova Factory
M. J. Childress, G. Aldering, P. Antilogus +32
We present photometric and spectroscopic observations of galaxies hosting Type Ia supernovae (SNe Ia) observed by the Nearby Supernova Factory (SNfactory). Combining GALEX UV data…
Standardizing Type Ia Supernova Absolute Magnitudes Using Gaussian Process Data Regression
A. G. Kim, R. C. Thomas, G. Aldering +32
We present a novel class of models for Type Ia supernova time-evolving spectral energy distributions (SED) and absolute magnitudes: they are each modeled as stochastic functions de…
Spectrophotometric time series of SN 2011fe from the Nearby Supernova Factory
R. Pereira, R. C. Thomas, G. Aldering +36
We present 32 epochs of optical (3300-9700 Å) spectrophotometric observations of the nearby quintessential "normal" type Ia supernova (SN Ia) SN 2011fe in the galaxy M101, extendin…
Atmospheric extinction properties above Mauna Kea from the Nearby Supernova Factory spectro-photometric data set
C. Buton, Y. Copin, G. Aldering +30
We present a new atmospheric extinction curve for Mauna Kea spanning 3200--9700 Å. It is the most comprehensive to date, being based on some 4285 standard star spectra obtained on…
A Search for New Candidate Super-Chandrasekhar-Mass Type Ia Supernovae in the Nearby Supernova Factory Dataset
The Nearby Supernova Factory, :, R. Scalzo +32
We present optical photometry and spectroscopy of five type Ia supernovae discovered by the Nearby Supernova Factory selected to be spectroscopic analogues of the candidate super-C…
Constraining Type Ia supernova models: SN 2011fe as a test case
F. K. Roepke, M. Kromer, I. R. Seitenzahl +42
The nearby supernova SN 2011fe can be observed in unprecedented detail. Therefore, it is an important test case for Type Ia supernova (SN Ia) models, which may bring us closer to u…
Very Early Ultraviolet and Optical Observations of the Type Ia Supernova 2009ig
Ryan J. Foley, P. J. Challis, A. V. Filippenko +18
Supernova (SN) 2009ig was discovered 17 hours after explosion by the Lick Observatory Supernova Search, promptly classified as a normal Type Ia SN (SN Ia), peaked at V = 13.5 mag,…
Type Ia Supernova Carbon Footprints
R. C. Thomas, G. Aldering, P. Antilogus +32
We present convincing evidence of unburned carbon at photospheric velocities in new observations of 5 Type Ia supernovae (SNe Ia) obtained by the Nearby Supernova Factory. These SN…
The reddening law of Type Ia Supernovae: separating intrinsic variability from dust using equivalent widths
N. Chotard, E. Gangler, G. Aldering +28
We employ 76 type Ia supernovae with optical spectrophotometry within 2.5 days of B-band maximum light obtained by the Nearby Supernova Factory to derive the impact of Si and Ca fe…

We present Keck LRIS spectroscopy and -band photometry of the metal-poor, low-luminosity host galaxy of the super-Chandrasekhar mass Type Ia supernova SN 2007if. Deep imaging of…
Using Spectral Flux Ratios to Standardize SN Ia Luminosities
S. Bailey, G. Aldering, P. Antilogus +23
We present a new method to standardize Type Ia supernova (SN Ia) luminosities to ~<0.13 magnitudes using flux ratios from a single flux-calibrated spectrum per SN. Using Nearby Sup…
Initial Hubble Diagram Results from the Nearby Supernova Factory
S. Bailey, G. Aldering, P. Antilogus +22
The use of Type Ia supernovae as distance indicators led to the discovery of the accelerating expansion of the universe a decade ago. Now that large second generation surveys have…
