Abstract:

The filamentary structure apparent in the Las Campanas Redshift
Survey (LCRS) is real only up to scales of  80 H^{-1} Mpc, in the
LCRS -3 degree slice.  Filamentary features longer than 80 h^{-1}Mpc,
although identified, are not statistically significant; they arise
from chance alignments. For the five other LCRS slices, filaments of
lengths 50 h^{-1}to 70 h^{-1} Mpc are statistically significant, but
not beyond. These results indicate that while individual filaments up
to 80 h^{-1} Mpc are coherent features of the large scale structure
in the universe, the filaments interconnect by statistical chance to
form  the cosmic web of the filament-void network.
