Abstract:
We present grizP1 light curves of 146 spectroscopically confirmed
Type Ia supernovae (SNe Ia; 0.03<z<0.65) discovered during the first
1.5yr of the Pan-STARRS1 Medium Deep Survey. The Pan-STARRS1 natural
photometric system is determined by a combination of on-site
measurements of the instrument response function and observations of
spectrophotometric standard stars. We find that the systematic
uncertainties in the photometric system are currently 1.2% without
accounting for the uncertainty in the Hubble Space Telescope Calspec
definition of the AB system. A Hubble diagram is constructed with a
subset of 113 out of 146 SNe Ia that pass our light curve quality
cuts. The cosmological fit to 310 SNe Ia (113 PS1 SNe Ia + 222 light
curves from 197 low-z SNe Ia), using only supernovae (SNe) and
assuming a constant dark energy equation of state and flatness, yields
ω=-1.120-0.206+0.360(Stat)-0.291+0.269(Sys). When
combined with BAO+CMB(Planck)+H0, the analysis yields
ΩM=0.280-0.012+0.013 and ω=-1.166-0.069+0.072
including all identified systematics. The value of w is inconsistent
with the cosmological constant value of -1 at the 2.3σ level.
Tension endures after removing either the baryon acoustic oscillation
(BAO) or the H0 constraint, though it is strongest when including the
H0 constraint. If we include WMAP9 cosmic microwave background (CMB)
constraints instead of those from Planck, we find
ω=-1.124-0.065+0.083, which diminishes the discord to
<2σ. We cannot conclude whether the tension with flat
ΛCDM is a feature of dark energy, new physics, or a combination
of chance and systematic errors. The full Pan-STARRS1 SN sample with
∼three times as many SNe should provide more conclusive results.
Description:
Spectroscopic observations of Pan-STARRS1 (PS1) targets were obtained
with a wide variety of instruments: the Blue Channel Spectrograph and
Hectospec on the 6.5m MMT, the Gemini Multi-Object Spectrographs
(GMOS) on both Gemini North and South, the Low Dispersion Survey
Spectrograph-3 (LDSS322) and the Magellan Echellette (MagE) on the
6.5m Magellan Clay telescope, and the Inamori-Magellan Areal Camera
and Spectrograph (IMACS) on the 6.5m Magellan Baade telescope, and the
ISIS spectrograph on the WHT.
