An improved standardization framework for Type II-P supernovae using a hierarchical Bayesian approach
A. Holas, S. Taubenberger, C. Vogl +41
We use Type II-P supernovae (SNe II-P) observed as part of the Nearby Supernova Factory (SNfactory) experiment as standardizable candles to develop an improved standardization fram…
Turning noise into signal: learning from the scatter in the Hubble diagram
Tiago Castro, Miguel Quartin, Sandra Benitez-Herrera
The supernova (SN) Hubble diagram residual contains valuable information on both the present matter power spectrum and its growth history. In this paper we show that this informati…
Massive stars exploding in a He-rich circumstellar medium. VI. Observations of two distant Type Ibn supernova candidates discovered by La Silla-QUEST
A. Pastorello, E. Hadjiyska, D. Rabinowitz +31
We present optical observations of the peculiar stripped-envelope supernovae (SNe) LSQ12btw and LSQ13ccw discovered by the La Silla-QUEST survey. LSQ12btw reaches an absolute peak…
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…
OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation
C. Inserra, S. A. Sim, L. Wyrzykowski +31
We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred reds…
Cosmological Parameter Estimation from SN Ia data: a Model-Independent Approach
S. Benitez-Herrera, E. E. O. Ishida, M. Maturi +4
We perform a model independent reconstruction of the cosmic expansion rate based on type Ia supernova data. Using the Union 2.1 data set, we show that the Hubble parameter behaviou…
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…
PESSTO monitoring of SN 2012hn: further heterogeneity among faint type I supernovae
S. Valenti, F. Yuan, S. Taubenberger +24
We present optical and infrared monitoring data of SN 2012hn collected by the Public ESO Spectroscopic Survey for Transient Objects (PESSTO). We show that SN 2012hn has a faint pea…
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…
Model-Independent Reconstruction of the Expansion History of the Universe from Type Ia Supernovae
S. Benitez-Herrera, F. Roepke, W. Hillebrandt +3
Based on the largest homogeneously reduced set of Type Ia supernova luminosity data currently available -- the Union2 sample -- we reconstruct the expansion history of the Universe…
