A new method to improve photometric redshift reconstruction. Applications to the Large Synoptic Survey Telescope
Alexia Gorecki, Alexandra Abate, Réza Ansari +4
In the next decade, the LSST will become a major facility for the astronomical community. However accurately determining the redshifts of the observed galaxies without using spectr…
Supernova Constraints and Systematic Uncertainties from the First 3 Years of the Supernova Legacy Survey
A. Conley, J. Guy, M. Sullivan +33
We combine high redshift Type Ia supernovae from the first 3 years of the Supernova Legacy Survey (SNLS) with other supernova (SN) samples, primarily at lower redshifts, to form a…
SNLS3: Constraints on Dark Energy Combining the Supernova Legacy Survey Three Year Data with Other Probes
M. Sullivan, J. Guy, A. Conley +33
We present observational constraints on the nature of dark energy using the Supernova Legacy Survey three year sample (SNLS3) of Guy et al. (2010) and Conley et al. (2011). We use…
The Supernova Legacy Survey 3-year sample: Type Ia Supernovae photometric distances and cosmological constraints
J. Guy, M. Sullivan, A. Conley +31
We present photometric properties and distance measurements of 252 high redshift Type Ia supernovae (0.15 < z < 1.1) discovered during the first three years of the Supernova Legacy…
Investigating The Uncertainty On The BAO Scale Measured From Future Photometric And Spectroscopic Surveys
Alexandra Abate, Alexia Gorecki, Reza Ansari +4
The Large Synoptic Survey Telescope (LSST) is a wide (20,000 sq.deg.) and deep ugrizy imaging survey which will be sited at Cerro Pachon in Chile. A major scientific goal of LSST i…
The ESO/VLT 3rd year Type Ia supernova data set from the Supernova Legacy Survey
C. Balland, S. Baumont, S. Basa +24
We present 139 spectra of 124 Type Ia supernovae (SNeIa) that were observed at the ESO/VLT during the first three years of the Canada-France-Hawai Telescope (CFHT) Supernova Legacy…
