The Carnegie Supernova Project: Analysis of the First Sample of Low-Redshift Type-Ia Supernovae
An analysis of the first set of low-redshift (z < 0.08) Type Ia supernovae (SNe Ia) monitored by the Carnegie Supernova Project between 2004 and 2006 is presented. The data consist of well-sampled,Expand
Characterizing the V-band light-curves of hydrogen-rich type II supernovae
We present an analysis of the diversity of V-band light-curves of hydrogen-rich type II supernovae. Analyzing a sample of 116 supernovae, several magnitude measurements are defined, together withExpand
No supernovae associated with two long-duration γ-ray bursts
It is now accepted that long-duration γ-ray bursts (GRBs) are produced during the collapse of a massive star1,2. The standard ‘collapsar’ model3 predicts that a broad-lined and luminous type IcExpand
Extensive HST ultraviolet spectra and multiwavelength observations of SN 2014J in M82 indicate reddening and circumstellar scattering by typical dust
SN 2014J in M82 is the closest detected Type Ia supernova (SN Ia) in at least 28 years and perhaps in 410 years. Despite its small distance of 3.3 Mpc, SN 2014J is surprisingly faint, peaking at V =Expand
The sloan digital sky survey-II supernova survey: technical summary
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) usingExpand
Constraints on the progenitor systems of type Ia supernovae
Bolometric light curves provide a valuable insight into the nature of type Ia supernovae. We present an analysis of sixteen well-observed type Ia supernovae. Constraints are placed on several globalExpand
A relativistic type Ibc supernova without a detected γ-ray burst
The discovery of luminous radio emission from the seemingly ordinary type Ibc SN 2009bb, which requires a substantial relativistic outflow powered by a central engine, is reported. Expand
The Carnegie Supernova Project: Light-curve Fitting with SNooPy
In providing an independent measure of the expansion history of the universe, the Carnegie Supernova Project (CSP) has observed 71 high-z Type Ia supernovae (SNe Ia) in the near-infrared bands Y andExpand
On the source of the dust extinction in type Ia supernovae and the discovery of anomalously strong Na i absorption
High-dispersion observations of the Na I D λλ5890, 5896 and K I λλ7665, 7699 interstellar lines, and the diffuse interstellar band at 5780 A in the spectra of 32 Type Ia supernovae are used as anExpand
Lower limits on the Hubble constant from models of type Ia supernovae
By coupling observations of type Ia supernovae with results obtained from the best available numerical mod- els we constrain the Hubble constant, independently of any external calibrators. We find anExpand
