...Observational probes of dark energy are reviewed by, e.g., Albrecht et al. (2006), Frieman, Turner, & Huterer (2008), Blanchard (2010), Astier & Pain (2012), and more comprehensively by Weinberg et al. (2013)....

...The physics of BAO and contemporary methods of BAO analysis are reviewed at length in Ch. 4 of Weinberg et al. (2013), and details specific to our analyses appear in the supporting papers listed below....

...To date the best constraints come from measuring the distance–redshift relation over as wide a range of redshifts as possible (Weinberg et al. 2013), and imply that the expansion rate of the Universe has recently transitioned from a deceleration to an acceleration phase (Riess et al. 1998;…...

...…by 1998 the two teams had converged on a remarkable result: when compared to local Type Ia supernovae (Hamuy et al., 1996), the supernovae at z ≈ 0.5 were fainter than expected in a matter-dominated universe with Ωm ≈ 0.2 by about 0.2 mag, or 20% (Riess et al., 1998; Perlmutter et al., 1999)....

...In the late 1990s, however, two independent studies of distant supernovae found that the expansion of the universe has accelerated over the last five billion years (Riess et al., 1998; Perlmutter et al., 1999), a remarkable discovery that is now buttressed by multiple lines of independent evidence....

...…to SN or SNe) are the most straightforward tool for studying cosmic acceleration, and they are the tool that directly discovered acceleration in the first place (Riess et al. 1998; Perlmutter et al. 1999; both using local calibration samples from the Calàn/Tololo survey, Hamuy et al. 1996)....

...When the ratio of extinction to reddening is treated as a free parameter in the cosmological fits, the derived values are typically quite far from those measured for Galactic interstellar dust, e.g., RV ≡ AV /E(B − V ) = 1.5− 2.5 (Hicken et al. 2009b; Kessler et al. 2009; Sullivan et al. 2011) instead of the mean RV = 3.1 found in the diffuse interstellar medium of the Milky Way (Cardelli et al., 1989)....
