Abstract:
The coming era of large photometric wide-field surveys will increase
the detection rate of supernovae by orders of magnitude. Such numbers
will restrict spectroscopic follow-up in the vast majority of cases,
and hence new methods based solely on photometric data must be
developed. Here, we construct a complete Hubble diagram of Type II
supernovae (SNe II) combining data from three different samples: the
Carnegie Supernova Project-I, the Sloan Digital Sky Survey II SN, and
the Supernova Legacy Survey. Applying the Photometric Color Method
(PCM) to 73 SNe II with a redshift range of 0.01-0.5 and with no
spectral information, we derive an intrinsic dispersion of 0.35mag. A
comparison with the Standard Candle Method (SCM) using 61 SNe II is
also performed and an intrinsic dispersion in the Hubble diagram of
0.27mag, i.e., 13% in distance uncertainties, is derived. Due to the
lack of good statistics at higher redshifts for both methods, only
weak constraints on the cosmological parameters are obtained. However,
assuming a flat universe and using the PCM, we derive the universe's
matter density: Ωm=0.32-0.21+0.30 providing a new
independent evidence for dark energy at the level of two sigma.
Description:
The CSP-I (Carnegie Supernova Project-I) had guaranteed access to ∼300
nights per year between 2004 and 2009 on the Swope 1m and du Pont 2.5m
telescopes at the Las Campanas Observatory (LCO). This observation
time allowed the CSP-I to obtain optical-band light curves for 67 SNe
II. From the CSP-I sample, we remove six outliers.
The SDSS-II SN Survey operated for three years, from 2005 September to
2007 November. Using the 2.5m telescope at the Apache Point
Observatory in New Mexico. This survey observed about 80
spectroscopically confirmed core-collapse SNe but the main driver of
this project was the study of SNe Ia, involving the acquisition of
only one or two spectra per SNe II. The total SDSS-II SN sample is
composed of 16 spectroscopically confirmed SNe II.
The SNLS (Supernova Legacy Survey) was designed to discover SNe and to
obtain photometric follow-up using the MegaCam imager on the 3.6m
Canada-France-Hawaii Telescope. The observation strategy consisted of
obtaining images of the same field every four nights over five years
(between 2003 and 2008); thus, in total more than 470 nights were
allocated to this project. The total SNLS sample is composed of 28 SNeII.
See section 2 for further explanations on the data sample.
