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…
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…
Keck Observations of the Young Metal-Poor Host Galaxy of the Super-Chandrasekhar-Mass Type Ia Supernova SN 2007if
M. Childress, G. Aldering, C. Aragon +28
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…
Nearby Supernova Factory Observations of SN 2007if: First Total Mass Measurement of a Super-Chandrasekhar-Mass Progenitor
R. A. Scalzo, G. Aldering, P. Antilogus +27
We present photometric and spectroscopic observations of SN 2007if, an overluminous (M_V = -20.4), red (B-V = 0.16 at B-band maximum), slow-rising (t_rise = 24 days) type Ia supern…
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…
