The Host Galaxies of Type Ia Supernovae Discovered by the Palomar Transient Factory
Y. -C. Pan, M. Sullivan, K. Maguire +16
We present spectroscopic observations of the host galaxies of 82 low-redshift type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory (PTF). We determine star-forma…
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…
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…
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…
The Hubble Space Telescope Cluster Supernova Survey: VI. The Volumetric Type Ia Supernova Rate
K. Barbary, G. Aldering, R. Amanullah +40
We present a measurement of the volumetric Type Ia supernova (SN Ia) rate out to z ~ 1.6 from the Hubble Space Telescope Cluster Supernova Survey. In observations spanning 189 orbi…
The Hubble Space Telescope Cluster Supernova Survey: V. Improving the Dark Energy Constraints Above z>1 and Building an Early-Type-Hosted Supernova Sample
N. Suzuki, D. Rubin, C. Lidman +62
We present ACS, NICMOS, and Keck AO-assisted photometry of 20 Type Ia supernovae SNe Ia from the HST Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval…
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…
Spectra and Light Curves of Six Type Ia Supernovae at 0.511 < z < 1.12 and the Union2 Compilation
R. Amanullah, C. Lidman, D. Rubin +42
We report on work to increase the number of well-measured Type Ia supernovae (SNe Ia) at high redshifts. Light curves, including high signal-to-noise HST data, and spectra of six S…
An Intensive HST Survey for z>1 Supernovae by Targeting Galaxy Clusters
K. S. Dawson, G. Aldering, R. Amanullah +57
We present a new survey strategy to discover and study high redshift Type Ia supernovae (SNe Ia) using the Hubble Space Telescope (HST). By targeting massive galaxy clusters at 0.9…
