Dark energy appears to be the dominant component of the physical Universe, yet there is no persuasive theoretical explanation for its existence or magnitude. The acceleration of the Universe is, along with dark matter, the observed phenomenon that most directly demonstrates that our theories of fundamental particles and gravity are either incorrect or incomplete. Most experts believe that nothing short of a revolution in our understanding of fundamental physics will be required to achieve a full understanding of the cosmic acceleration. For these reasons, the nature of dark energy ranks among the very most compelling of all outstanding problems in physical science. These circumstances demand an ambitious observational program to determine the dark energy properties as well as possible.

KiDS-450: cosmological parameter constraints from tomographic weak gravitational lensing (2016, background): “…tomographic cosmic shear technique are its relative insensitivity to galaxy biasing, its clean theoretical description (though there are complications due to baryon physics; see e.g. Semboloni et al. 2011), and its immense potential statistical power compared to other probes (Albrecht et al. 2006).”
Gravitational lensing analysis of the Kilo-Degree Survey (2015, background): “…from HSC, see Miyazaki et al. 2015), KiDS aims to exploit the evolution of the density of clustered matter on large scales as a cosmological probe (Albrecht et al. 2006; Peacock et al. 2006), as well as to study the distribution of dark matter around galaxies with more accuracy than has been…”
CFHTLenS: combined probe cosmological model comparison using 2D weak gravitational lensing (2012, methodology): “The measurement of the lensing correlations for different redshift combinations allows us to obtain information on the growth of structure (e.g. Hu 1999), and has a great potential to constrain dark energy and modified gravity models (e.g. Albrecht et al. 2006; Uzan 2010).”
Cosmic chronometers: constraining the equation of state of dark energy. I: H(z) measurements (2009, unknown): “As argued in the ESO/ESA and Dark Energy Task Force reports [8, 10], robust conclusions about the cosmic expansion history will likely require several avenues to allow for cross checks.”

The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample (2016, background): “Observational probes of dark energy are reviewed by, e.g., Albrecht et al.

Toward a Halo Mass Function for Precision Cosmology: The Limits of Universality (2008, unknown): “In addition, clusters probe the growth of structure in the Universe, which provides constraints different from and complementary to the geometric constraints by the supernovae type Ia (e.g., Albrecht et al. 2006).”
The clustering of galaxies in the SDSS‐III Baryon Oscillation Spectroscopic Survey: cosmological implications of the large‐scale two‐point correlation function (2012, background): “A useful quantity to characterize the constraints on the redshift evolution of the dark energy equation of state is the pivot redshift, zp, defined as the point where the uncertainty on wDE(a) is minimized (Huterer & Turner 2001; Hu & Jain 2004; Albrecht et al. 2006).”
KiDS-1000 cosmology: Cosmic shear constraints and comparison between two point statistics (2020, background): “…gravitational lensing effect that coherently distorts the shapes of galaxy images, commonly referred to as cosmic shear, was hailed as such a tool (Albrecht et al. 2006; Peacock et al. 2006); It directly maps the spatial distribution of all gravitating matter along the line of sight and is…”

PHAT: PHoto-z Accuracy Testing (2010, background): “Photo-z’s are essential in constraining dark energy (DE) by weak gravitational lensing and can be used for other DE probes such as galaxy clustering, supernovae of type Ia, and the mass function of galaxy clusters as well (Albrecht et al. 2006; Peacock et al. 2006).”
The clustering of galaxies in the sdss-iii baryon oscillation spectroscopic survey: Baryon acoustic oscillations in the data release 9 spectroscopic galaxy sample (2012, methodology): “The latter was recommended by the Dark Energy Task Force (hereafter DETF; Albrecht et al. 2006) for dark energy Figure-of-Merit comparisons.”
