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 کاملThe Las Campanas Redshift Survey Results: the Redshift-space Autocorrelation Function
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 clo...
متن کاملThe Galaxy-weighted Small-scale Velocity Dispersion of the Las Campanas Redshift Survey
The pair-weighted relative velocity dispersion of galaxies provides a measure of the thermal energy of fluctuations of the observed galaxy distribution, but the measure is difficult to interpret and is very sensitive to the existence of rare, rich clusters of galaxies. Several alternative statistical procedures have recently been suggested to relieve these problems. We apply a variant of the ob...
متن کاملThe Power Spectrum of Galaxy Clustering in the Las Campanas Redshift Survey
We present the power spectrum P (k), over scales = 2 =k = 5 400 h 1 Mpc, for a magnitude-limited sample of 19276 Las Campanas Redshift Survey (LCRS) galaxies, with average redshift z 0:1. The LCRS P (k) may be approximated as / k 1:8 for small scales = 5 30 h 1 Mpc, changing to / k 1 1 for large scales 200 400 h 1 Mpc. The overall amplitude corresponds to 8 = 1 in redshift space. We also compar...
متن کاملThe Las Campanas Infrared Survey . IV . The Photometric Redshift Survey and the Rest - frame R - band Galaxy Luminosity Function at
We present rest-frame R-band galaxy luminosity function measurements for three different redshift ranges: 0.5 ≤ z ≤ 0.75, 0.75 ≤ z ≤ 1.0, and 1.0 ≤ z ≤ 1.5. Our measurements are based on photometric redshifts for ∼ 3000 H-band selected galaxies with apparent magnitudes 17 ≤ H ≤ 20 from the Las Campanas Infrared Survey. We show that our photometric redshifts are accurate with an RMS dispersion b...
