The Las Campanas Redshift Survey Results: the Redshift-space Autocorrelation Function
نویسنده
چکیده
Presented are measurements from the Las Campanas Redshift Survey (LCRS) of the galaxy-galaxy autocorrelation function in redshift-space, gg (s). For separations 2:0h ?1 Mpc < s < 16:4h ?1 Mpc, gg (s) can be approximated by a power law with slope = ?1:52 0:03 and correlation length s 0 = 6:28 0:27h ?1 Mpc. A zero-crossing occurs on scales of 30 ? 40h ?1 Mpc. On larger scales, gg (s) uctuates closely about zero, indicating a high level of uniformity in the galaxy distribution on these scales. In addition, a selection eeect inherent to the LCRS { the 55 arcsec galaxy pair separation limit { is tested and found to have little impact on the measurement of gg (s).

The Galaxy-galaxy Autocorrelation Function for the Las Campanas Redshift Survey
The Las Campanas Redshift Survey (LCRS) is a galaxy survey which extends to a red-shift of 0.2 and which is composed of a total of 6 alternating 1:5 80 Slices in the North and South Galactic Caps. Now in its nal stages, the Survey contains approximately 26,400 galaxy redshifts. We present here a deenitive LCRS galaxy-galaxy autocorrela-tion function gg (s), its comparison to the gg (s) from var...
متن کاملLas Campanas Redshift Survey Results: the 3d Power Spectrumand the Luminosity Function
Some recent results on the galaxy 3D power spectrum and the luminosity function derived from the Las Campanas Redshift Survey (LCRS) are discussed. We will present the LCRS power spectrum, compare it against results from other local redshift surveys, and use it to constrain a number of cold dark matter structure formation models. Then we will proceed to describe the LCRS luminosity function, as...
متن کاملThe Pairwise Velocity Distribution of Galaxies in the Las Campanas Redshift Survey
We present a novel measurement of the pairwise peculiar velocity distribution function of galaxies on scales r < 3200 km sec in the Las Campanas Redshift Survey. The distribution is well described by a scale-independent exponential with a width τ where σ12 = √ 2τ = 363 km sec. The signal is very stable. Results from the Northern and Southern sets of slices agree within ±13 km sec and the fluctu...
متن کاملDensity-Dependent Luminosity Functions for Galaxies in the Las Campanas Redshift Survey
Galaxies in the Las Campanas Redshift Survey are classified according to their spectra, and the resulting spectral types are analyzed to determine if local environment affects their properties. We find that the luminosity function of early-type objects varies as a function of local density. Our results suggest that early-type galaxies (presumably ellipticals and S0’s) are, on average, fainter w...
متن کاملTopology of the Las Campanas Redshift Survey
The topology of the Las Campanas Redshift Survey is analyzed using Minkowski functional statistics, taking into account the selection effects of the survey. The results are compared with the predictions of some toy models of structure formation, including the Standard Cold Dark Matter Model and topological defect-based models. All of the toy models have a scale invariant primordial spectrum of ...
