SNEMO: Improved Empirical Models for Type Ia Supernovae

C. Saunders, G. Aldering, P. Antilogus +39

Type Ia supernova cosmology depends on the ability to fit and standardize observations of supernova magnitudes with an empirical model. We present here a series of new models of Ty…

SCALA: In-situ calibration for Integral Field Spectrographs

S. Lombardo, D. Küsters, M. Kowalski +39

The scientific yield of current and future optical surveys is increasingly limited by systematic uncertainties in the flux calibration. This is the case for Type Ia supernova (SN I…

The Extinction Properties of and Distance to the Highly Reddened Type Ia Supernova SN 2012cu

X. Huang, Z. Raha, G. Aldering +39

Correction of Type Ia Supernova brightnesses for extinction by dust has proven to be a vexing problem. Here we study the dust foreground to the highly reddened SN 2012cu, which is…

Improving Cosmological Distance Measurements Using Twin Type Ia Supernovae

H. K. Fakhouri, K. Boone, G. Aldering +41

We introduce a method for identifying "twin" Type Ia supernovae, and using them to improve distance measurements. This novel approach to Type Ia supernova standardization is made p…

Confirmation of a Star Formation Bias in Type Ia Supernova Distances and its Effect on Measurement of the Hubble Constant

M. Rigault, G. Aldering, M. Kowalski +35

Previously we used the Nearby Supernova Factory sample to show that SNe~Ia having locally star-forming environments are dimmer than SNe~Ia having locally passive environments.Here…

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…

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…

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…
