Simulations of deep pencil-beam redshift surveys
We create mock pencil-beam redshift surveys from very large cosmological N -body simulations of two Cold Dark Matter cosmogonies, an Einstein-de Sitter model (τCDM) and a flat model with Ω0 = 0.3 and a cosmological constant (ΛCDM). We use these to assess the significance of the apparent periodicity discovered by Broadhurst et al. (1990). Simulation particles are tagged as ‘galaxies’ so as to re...
متن کاملLarge-scale distribution of quasars in deep pencil-beam surveys
We have used integral two-point spatial correlation function and its second derivative to analyze the distribution of quasars in three very deep surveys published in the literature. Statistically significant (∼ 2 − 3σ) correlations were found at scales of ∼ 50 − 100h Mpc in all of the analyzed surveys. We have used the friend-of-friend cluster analysis to show that these correlations can be exp...
متن کاملNon-Gaussian statistics of pencil beam surveys
We study the effect of the non-Gaussian clustering of galaxies on the statistics of pencil beam surveys. We find that the higher order moments of the galaxy distribution play an important role in the probability distribution for the power spectrum peaks. Taking into account the observed values for the kurtosis of galaxy distribution we derive the general probability distribution for the power s...
متن کاملMeasuring Galaxy Environments with Deep Redshift Surveys
We study the applicability of several galaxy environment measures (n-nearest-neighbor distance, counts in an aperture, and Voronoi volume) within deep redshift surveys. Mock galaxy catalogs are employed to mimic representative photometric and spectroscopic surveys at high redshift (z ∼ 1). We investigate the effects of survey edges, redshift precision, redshift-space distortions, and target sel...
متن کاملGalaxy Statistics in Pencil-beam Surveys at High Redshifts
Surveys of faint galaxies at high redshifts often result in a “pencil-beam” geometry that is much longer along the line-of-sight than across the sky. We explore the effects of this geometry on the abundance and clustering of Lyman-break galaxies (LBGs) and Lyman-α emitters (LAEs) based on cosmological N-body simulations which adequately describe the nonlinear growth of structure on small scales...
