Carnegie Supernova Project-I and -II: Measurements of using Cepheid, TRGB, and SBF Distance Calibration to Type Ia Supernovae
Syed A. Uddin, Christopher R. Burns, Mark M. Phillips +44
We present an analysis of Type Ia Supernovae (SNe~Ia) from both the Carnegie Supernova Project~I (CSP-I) and II (CSP-II), and extend the Hubble diagram from the optical to the near…
The Carnegie Supernova Project: Absolute Calibration and the Hubble Constant
Christopher. R. Burns, Emilie Parent, M. M. Phillips +23
We present an analysis of the final data release of the Carnegie Supernova Project I, focusing on the absolute calibration of the luminosity-decline-rate relation for Type Ia super…
First Results from the La Silla-QUEST Supernova Survey and the Carnegie Supernova Project
E. S. Walker, C. Baltay, A. Campillay +20
The LaSilla/QUEST Variability Survey (LSQ) and the Carnegie Supernova Project (CSP II) are collaborating to discover and obtain photometric light curves for a large sample of low r…
The Carnegie Supernova Project: Intrinsic Colors of Type Ia Supernovae
Christopher R. Burns, Maximilian Stritzinger, M. M. Phillips +12
We present an updated analysis of the intrinsic colors of SNe Ia using the latest data release of the Carnegie Supernova Project. We introduce a new light-curve parameter very simi…
On the Source of the Dust Extinction in Type Ia Supernovae and the Discovery of Anomalously Strong Na I Absorption
M. M. Phillips, Joshua D. Simon, Nidia Morrell +28
High-dispersion observations of the Na I D 5890, 5896 and K I 7665, 7699 interstellar lines, and the diffuse interstellar band at 5780 Angstroms in the spectra of 32 Type Ia supern…
Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Project
Gastón Folatelli, Nidia Morrell, Mark M. Phillips +27
This is the first release of optical spectroscopic data of low-redshift Type Ia supernovae (SNe Ia) by the Carnegie Supernova Project including 604 previously unpublished spectra o…
Carnegie Supernova Project: Observations of Type IIn supernovae
F. Taddia, M. D. Stritzinger, J. Sollerman +16
The observational diversity displayed by various Type IIn supernovae (SNe IIn) is explored and quantified. In doing so, a more coherent picture ascribing the variety of observed SN…
Multi-wavelength Observations of the Enduring Type IIn Supernovae 2005ip and 2006jd
Maximilian Stritzinger, Francesco Taddia, Claes Fransson +19
We present an observational study of the Type IIn supernovae (SNe IIn) 2005ip and 2006jd. Broad-band UV, optical and near-IR photometry, and visual-wavelength spectroscopy of SN 20…
Unburned Material in the Ejecta of Type Ia Supernovae
Gastón Folatelli, M. M. Phillips, Nidia Morrell +17
(Abridged) The presence of unburned material in the ejecta of normal Type Ia supernovae (SNeIa) is investigated using early-time spectroscopy obtained by the CSP. The tell-tale sig…
The Carnegie Supernova Project: Second Photometry Data Release of Low-Redshift Type Ia Supernovae
Maximilian Stritzinger, M. M. Phillips, Luis Boldt S. +20
The Carnegie Supernova Project (CSP) was a five-year observational survey conducted at Las Campanas Observatory that obtained, among other things, high-quality light curves of ~100…
The Carnegie Supernova Project: Light Curve Fitting with SNooPy
Christopher R. Burns, Maximilian Stritzinger, M. M. Phillips +13
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-in…
The Distance to NGC 1316 (Fornax A) From Observations of Four Type Ia Supernovae
Maximilian Stritzinger, Chris Burns, Mark Phillips +13
The giant elliptical galaxy NGC 1316 (Fornax A) is a well-studied member of the Fornax Cluster and a prolific producer of Type Ia supernovae, having hosted four observed events sin…
