Journal ArticleDOI
Dynamical effects of the cosmological constant.
TL;DR: In this article, the authors explored the possibility of measuring the density parameter OMEGA-0 and the cosmological constant lambda-0 = LAMBDA/(3H0(2)) using dynamical tests in linear and non-linear theory.
Journal ArticleDOI
A new nonparametric approach to galaxy morphological classification
TL;DR: In this paper, the relative distribution of the galaxy pixel flux values (the Gini coefficient or G) and the second-order moment of the brightest 20% of a galaxy's flux (M20) were measured and compared to decreasing signal-to-noise ratio (S/N) and spatial resolution.

TL;DR: In this article, the evolution of the spectrum of the EBL between 0.1 and 1000 µm has been determined directly from galaxy spectral energy distribution (SED) observations over a wide redshift range.
Journal ArticleDOI
The nature of high-redshift galaxies
TL;DR: In this paper, a collisional starburst model was proposed for high-redshift Lyman-break galaxies, where bursts of star formation are triggered by galaxy-galaxy mergers, and a significant fraction of LBGs are predicted to be starbursts.
