TL;DR: In this article, the authors used a prior based on the Two Degree Field (2dF) Redshift Survey constraint on ΩM and assuming a flat universe, they found that the equation of state parameter of the dark energy lies in the range -1.48 -1, and obtained w < -0.73 at 95% confidence.

TL;DR: The DEEP2 and COMBO-17 surveys are compared to study luminosity functions of red and blue galaxies to z ~ 1, and the results imply that the number and total stellar mass of blue galaxies have been substantially constant since z = 1, whereas those of red galaxies (near L*) have been significantly rising as mentioned in this paper.

TL;DR: In this paper, the DEEP2 and COMBO-17 surveys are used to study the evolution of the luminosity function of red and blue galaxies to $z \sim 1$ Schechter function fits show that, since $z = 1$, $M^*_B$ dims by $\sim$ 1.3 mag per unit redshift for both color classes, while red galaxies has formally nearly quadrupled.

Abstract: The DEIMOS spectrograph is a multi-object spectrograph being built for Keck II. DEIMOS was delivered in February 2002, became operational in May, and is now about three-quarters of the way through its commissioning period. This paper describes the major problems encountered in completing the spectrograph, with particular emphasis on optical quality and image motion. The strategies developed to deal with these problems are described. Overall, commissioning is going well, and it appears that DEIMOS will meet all of its major performance goals.

TL;DR: The All-Wavelength Extended Groth Strip International Survey (AEGIS) as mentioned in this paper was proposed to study the physical properties and evolutionary processes of galaxies at z = 1.5.
