Supernova Legacy Survey (snls): Real Time Operations and Photometric Analysis
نویسندگان
چکیده
Type Ia supernovae (SN Ia) have provided the first evidence for an accelerating universe and for the existence of an unknown “dark energy” driving this expansion. The 5-year Supernova Legacy Survey (SNLS) will deliver ∼700 type Ia supernovae and as many type II supernovae with wellsampled light curves in 4 filters g′, r′, i′ and z′. The current status of the project will be presented, along with the real time processing leading to the discovery and spectroscopic observation of the supernovae. We also present an offline selection of the SN candidates which aims at identifying and eliminating potential selection biases.

SNLS – the Supernova Legacy Survey
Type Ia supernovae (SNeIa) provide direct evidence for an accelerating universe, and for the existence of " dark energy " driving this expansion. The Supernova Legacy Survey (SNLS) will deliver many hundreds of SNIa detections, and well-sampled g ′ r ′ i ′ z ′ light curves, over the next 5 years. Using these data, we will obtain a precise measurement of the cosmological parameters (Ω mass , Ω Λ...
متن کاملA Model-independent Photometric Redshift Estimator for Type Ia Supernovae
The use of type Ia supernovae (SNe Ia) as cosmological standard candles is fundamental in modern observational cosmology. In this letter, we derive a simple empirical photometric redshift estimator for SNe Ia using a training set of SNe Ia with multiband (griz) light-curves and spectroscopic redshifts obtained by the Supernova Legacy Survey (SNLS). This estimator is analytical and model-indepen...
متن کاملThe Future of Photometric, Spectrophotometric and Polarimetric Standardization
The 5-year project Supernova Legacy Survey (SNLS) delivers ∼ 100 Type-Ia supernovae (SNe Ia) per year, in the redshift range 0.3 < z < 1.0, with well-sampled griz lightcurves. The SNLS Collaboration uses the 1 deg Megacam imager (36 2048×4612 thinned CCDs) mounted on the 3.6-m CanadaFrance-Hawaii Telescope (CFHT) to observe four fields around the sky, in four filters. The primary goal of the pr...
متن کاملSearch For Type Ia Supernova NUV-Optical Subclasses
In response to a recently reported observation of evidence for two classes of Type Ia Supernovae (SNe Ia) distinguished by their brightness in the rest-frame near ultraviolet (NUV), we search for the phenomenon in publicly available light-curve data. We use the SNANA supernova analysis package to simulate SN Ia-light curves in the Sloan Digital Sky Survey Supernova Search (SDSS) and the Superno...
متن کاملConfronting Braneworld Cosmology with Supernova data and Baryon Oscillations
Braneworld cosmology has several attractive and distinctive features. For instance the effective equation of state in braneworld models can be both quintessence-like (w0 ≥ −1) as well as phantomlike (w0 ≤ −1). Models with w0 ≥ −1 (w0 ≤ −1) are referred to as Brane 2 (Brane 1) and correspond to complementary embeddings of the brane in the bulk. (The equation of state in Brane 1 can successfully ...
