The Case for an Accelerating Universe from Supernovae

148 citations recorded by the source corpus.

The unexpected faintness of high‐redshift Type Ia supernovae (SNe Ia), as measured by two teams, has been interpreted as evidence that the expansion of the universe is accelerating. We review the current challenges to this interpretation and seek to answer whether the cosmological implications are compelling. We discuss future observations of SNe Ia which could offer extraordinary evidence to test acceleration.

Observational Constraints on the Nature of Dark Energy: First Cosmological Results from the ESSENCE Supernova Survey (2007, background): “…Ia at z ≈ 0.5 were about 0.2 mag dimmer than expected in an open universe and pointed firmly at an accelerating universe (for first-hand accounts, see Overbye 1999; Riess 2000; Filippenko 2001; Kirshner 2002; Perlmutter 2003); reviews are given by Leibundgut (2001), Filippenko (2005b) and others.”
Cosmological parameters from supernova observations: A critical comparison of three data sets (2003, background): “We summarize the key results once more: • It has been well known that the supernova data rule out the flat and open matter-dominated models with a high degree of confidence (Riess et al. 1998; Perlmutter et al. 1999; Riess 2000).”
A Model-Independent Determination of the Expansion and Acceleration Rates of the Universe as a Function of Redshift and Constraints on Dark Energy (2003, background): “…background (CMB) fluctuations (e.g., Bennett et al. 2003; Spergel et al. 2003, and references therein), the use of distant supernovae (SNe) in a Hubble diagram (see, e.g., Riess 2000; Leibundgut 2001, and references therein), radio galaxies (e.g., Daly & Guerra 2002), and many other advances.”
A local void and the accelerating Universe (2000, background): “So far the observed data of SNIa have been compared with the theoretical relation in homogeneous and isotropic models, and many workers have made efforts to determine their model parameters (Garnavich et al. 1998; Schmidt et al. 1998; Perlmutter et al. 1999; Riess et al. 1998, 2000; Riess 2000).”
Do Type Ia Supernovae Provide Direct Evidence for Past Deceleration of the Universe? (2001, background): “…z 1:2 (Tonry et al. 2001; Aldering et al. 2001) disfavor the two simple alternates to an accelerating universe—intergalactic dust and SN luminosity evolution (see, e.g., Drell, Loredo, & Wasserman 2000; Aguire 1999a, 1999b; Riess 2000)—and bolster the case for the accelerating universe hypothesis.”
Hubble Space Telescope and Ground-based Observations of Type Ia Supernovae at Redshift 0.5: Cosmological Implications (2005, background): “Reviews with more detail on this remarkable paradigm shift are given by Riess (2000), Leibundgut (2001),Carroll (2001), Perlmutter&Schmidt (2003), andFilippenko (2001, 2004).”
COSMOLOGICAL IMPLICATIONS FROM OBSERVATIONS OF TYPE IA SUPERNOVAE (2001, methodology): “The reader is referred to Riess (2000), Leibundgut (2000b), Filippenko & Riess (2000), for a specific discussion of the SN results and to Turner & Tyson (1999) and Bahcall et al. (1999) for more general overviews.”
Dilaton gravity in two-dimensions (2002, background): “Recently in connection with the observation of supernovae at high values of the redshift [367, 365, 366, 359] the validity of the HilbertEinstein theory has been put into doubt [12].”
Cosmological Results from High-z Supernovae (2003, background): “The most likely contaminants of the cosmological signal from SNe Ia are luminosity evolution, gray intergalactic dust, gravitational lensing, or selection biases (see Riess 2000; Filippenko & Riess 2001; Leibundgut 2001 for reviews).”
Dark Energy and the Accelerating Universe (2008, unknown): “Figure adapted from Perlmutter & Schmidt (2003) and Riess (2000), based on Riess et al. (1998) and Perlmutter et al. (1999).”
A theoretician's analysis of the supernova data and the limitations in determining the nature of dark energy (2002, methodology): “The supernova data on the whole, rules out non-acceleratingmodels with very high significance level, as noted and stressed by various authors (Riess et al. 1998; Perlmutter et al. 1999; Riess2000).”
