“…The favorite standard candle is SNe Ia, and observers are now in good agreement. Taking account of an empirical relationship between the SNe Ia light curve shape and maximum luminosity leads to h = 0.65 ± 0.06 [103], h = 0.64 +0.08 −0.06 [61], or h = 0.63 ± 0.03 [52,93], and the slightly lower value mentioned above from the latest analysis coauthored by Sandage and Tammann agrees within the errors. The HST Key Project result using SNe Ia is h = 0.65 ± 0.02 ± 0.05, where the first error quoted is statistical and the second is systematic [50], and their Cepheid metallicity-dependent luminosity-period relationship [65] has been used (this lowers h by 4%).…”

“…This correlation, which we will refer to generically as the luminosity-LCS relation, was first quantified by Phillips (1993) based on a handful of objects including the archetypes of low and high luminosity Ia supernovae, SN 1991bg and SN 1991T, respectively. Also important to the refinement of distance determinations was the development of corrections for the correlation between SN color and extinction (Riess et al, 1996;Tripp, 1998;Phillips et al, 1999) and K-corrections for redshifting effects (Kim et al, 1996;Nugent et al, 2002). These were all quickly incorporated into analysis methods such as the Multicolor Light Curve Shape (MLCS; Riess et al 1996) technique used by the High-z Supernova Search (Schmidt et al, 1998) and the stretch-factor formalism used by the Supernova Cosmology Project (Perlmutter et al, 1997).…”

The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of "dark energy" with exotic physical properties, or that Einstein's theory of gravity breaks down on cosmological scales. The profound implications of cosmic acceleration have inspired ambitious efforts to understand its origin, with experiments that aim to measure the history of expansion and growth of structure with percent-level precision or higher. We review in detail the four most well established methods for making such measurements: Type Ia supernovae, baryon acoustic oscillations (BAO), weak gravitational lensing, and the abundance of galaxy clusters. We pay particular attention to the systematic uncertainties in these techniques and to strategies for controlling them at the level needed to exploit "Stage IV" dark energy facilities such as BigBOSS, LSST, Euclid, and WFIRST. We briefly review a number of other approaches including redshift-space distortions, the Alcock-Paczynski effect, and direct measurements of the Hubble constant H 0 . We present extensive forecasts for constraints on the dark energy equation of state and parameterized deviations from General Relativity, achievable with Stage III and Stage IV experimental programs that incorporate supernovae, BAO, weak lensing, and cosmic microwave background data. We also show the level of precision required for clusters or other methods to provide constraints competitive with those of these fiducial programs. We emphasize the value of a balanced program that employs several of the most powerful methods in combination, both to cross-check systematic uncertainties and to take advantage of complementary information. Surveys to probe cosmic acceleration produce data sets that support a wide range of scientific investigations, and they continue the longstanding astronomical tradition of mapping the universe in ever greater detail over ever larger scales.

“…There have been several focused searches for SNIa, which have produced large sets of well-sampled light curves (see, e.g., [42,44,46,50,66,73,88,91,92,97,107,112]). These data samples have produced a detailed view of SNIa.…”

Abstract. Photometry is the most easily acquired information about supernovae. The light curves constructed from regular imaging provide signatures not only for the energy input, the radiation escape, the local environment and the progenitor stars, but also for the intervening dust. They are the main tool for the use of supernovae as distance indicators through the determination of the luminosity.The light curve of SN1987A still is the richest and longest observed example for a core-collapse supernova. Despite the peculiar nature of this object, as explosion of a blue supergiant, it displayed all the characteristics of type II supernovae. The light curves of type Ib/c supernovae are more homogeneous, but still display the signatures of explosions in massive stars, among them early interaction with their circumstellar material.Wrinkles in the near-uniform appearance of thermonuclear (type Ia) supernovae have emerged during the past decade. Subtle differences have been observed especially at near infrared (NIR) wavelengths. Interestingly, the light curve shapes appear to correlate with a variety of other characteristics of these supernovae.The construction of bolometric light curves provides the most direct link to theoretical predictions and can yield sorely needed constraints for the models. First steps in this direction have been already made.
