  3. SN • CCSN rate in Arp299 arxiv: 1104.1955 • SNLS3: Constraints on Dark Energy Combining the Supernova Legacy Survey Three Year Data with Other Probes, M. Sullivan+, arXiv:1104.1444 • SUPERNOVA CONSTRAINTS AND SYSTEMATIC UNCERTAINTIES FROM THE FIRST 3 YEARS OF THE SUPERNOVA LEGACY SURVEY, A. Conley+, arXiv:1104.1443 Based on observations obtained with MegaPrime/MegaCam, a joint project of CFHT and CEA/DAPNIA, at the Canada-France-Hawaii Telescope (CFHT) which is operated by the National Re-search Council (NRC) of Canada, the Institut National des Sciences de l'Univers of the Centre National de la Recherche Scientique (CNRS) of France, and the University of Hawaii. This work is based in part on data products produced at the Canadian Astronomy Data Centre as part of the Canada-France-Hawaii Telescope Legacy Survey, a collaborative project of NRC and CNRS.
