Observational signatures of AT 2014ej reveal that it is … The La Silla/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-redshift (z < 0.1) Type Ia supernovae (SNe Ia). We present a study of observed Type II supernova (SN II) colours using optical/near-infrared photometric data from the Carnegie Supernovae Project-I. The Carnegie Supernova Project (CSP) is designed to measure the luminosity distance for Type Ia supernovae (SNe Ia) as a function of redshift, and to set observational constraints on the dark energy contribution to the total energy content of the universe.

Along with the accompanying paper, Phillips et al., we introduce the Carnegie Supernova Project-II (CSP-II), to follow-up nearby SNe Ia in both the optical and the NIR. The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and 2009. Along with the accompanying paper, Phillips et al. We therefore propose to embark on a long-term program, the Carnegie Supernova Project (CSP), with the goal of obtaining exceedingly-well calibrated optical/near-infrared light curves and optical spectroscopy of over 200 Type~Ia and Type~II supernovae. Eric Y. Hsiao SN Workshop at IPMU, December 13, 2012 CSP2 ‣ We propose to carry out a second stage of the CSP with the goal of producing optical and NIR light curves of 100-200 SNe Ia in the redshift The primary scientific motivation was to detect and measure light curves for several hundred supernovae through repeat scans of the SDSS Southern equatorial stripe 82 (about 2.5° wide by ~120° long).

Although this object spectroscopically resembles the well-observed SN 2010jl, it does exhibit different LC evolution and dust signatures. In particular, this paper focuses on the CSP-II NIR spectroscopy program, describing the survey strategy, instrumental setups, data reduction, sample characteristics, and future analyses on the data set. The data consist of well-sampled, high-precision optical (ugriBV) and near-infrared (NIR; YJHK{sub s} ) light curves in a well-understood photometric system. 2015, A&A phase coverage:-12.8 to 35.1 d past B maximum wavelength coverage: 0.83 to 2.50 micron NIR spectra of SN 2011fe download: SpeX + GNIRS spectra paper: Hsiao et al. 2015 as a part of the Carnegie Supernova Project-II (CSP-II; e.g., Phillips et al.

These observations are complemented with data from the CHilean Automatic Supernova sEarch, the Public ESO Spectroscopic Survey of Transient Objects, and from the Backyard Observatory Supernova Search. The Carnegie Supernova Project (CSP) is aimed at providing an independent measure of change in the the Hubble expansion as a function of redshift, and setting constraints dark energy contribution to the total energy content of the universe. The Carnegie Supernova Project II (CSP2) is one such survey that aims at achieving very high precision photometry.
