cds-question@unistra.frsupernovaeredshiftedvisible-astronomyspectroscopyphotometryWe present optical light curves, redshifts, and classifications for 365 spectroscopically confirmed Type Ia supernovae (SNe Ia) discovered by the Pan-STARRS1 (PS1) Medium Deep Survey. We detail improvements to the PS1 SN photometry, astrometry, and calibration that reduce the systematic uncertainties in the PS1 SN Ia distances. We combine the subset of 279 PS1 SNe Ia (0.03<z<0.68) with useful distance estimates of SNe Ia from the Sloan Digital Sky Survey (SDSS), SNLS, and various low-z and Hubble Space Telescope samples to form the largest combined sample of SNe Ia, consisting of a total of 1048 SNe Ia in the range of 0.01<z<2.3, which we call the "Pantheon Sample". When combining Planck 2015 cosmic microwave background (CMB) measurements with the Pantheon SN sample, we find {Omega}_m_=0.307+/-0.012 and w=-1.026+/-0.041 for the wCDM model. When the SN and CMB constraints are combined with constraints from BAO and local H_0_ measurements, the analysis yields the most precise measurement of dark energy to date: w_0_=-1.007+/-0.089 and w_a_=-0.222+/-0.407 for the w_0_w_a_CDM model. Tension with a cosmological constant previously seen in an analysis of PS1 and low-z SNe has diminished after an increase of 2x in the statistics of the PS1 sample, improved calibration and photometry, and stricter light-curve quality cuts. We find that the systematic uncertainties in our measurements of dark energy are almost as large as the statistical uncertainties, primarily due to limitations of modeling the low-redshift sample. This must be addressed for future progress in using SNe Ia to measure dark energy.2018ApJ...859..101Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/859/101CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)J/ApJ/607/665 : Type Ia supernovae at z>1 discovered by HST (Riess+, 2004)J/AJ/131/527 : UBVRI light curves of 44 type Ia supernovae (Jha+, 2006)J/AJ/131/1648 : Type Ia supernovae at high and low redshifts (Blondin+, 2006)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)J/ApJ/666/674 : ESSENCE supernova survey (Miknaitis+, 2007)J/AJ/136/2306 : SDSS-II Supernova survey, 2005 (Holtzman+, 2008)J/ApJ/700/331 : Light curves of type Ia supernovae (CfA3) (Hicken+, 2009)J/ApJ/700/1097 : Light curve parameters of SN Ia (Hicken+, 2009)J/ApJS/185/32 : First-year SDSS-II SN results (Kessler+, 2009)J/AJ/139/519 : Carnegie supernova project.
