Based on the disk-halo decomposition method introduced by Persic & Salucci, we use 58 spiral rotation curves to measure the galaxy-background correlation function in the range 3-350 kpc (for H0 = 50 km s-1 Mpc-1). We find that (1) the two-point function is zeta(r) congruent-to (r0/r)1.76, with r0 congruent-to 7 Mpc (for OMEGA-0 = 1), and (2) higher order correlation functions are detected up to the sixth order and are found to fit the hierarchical expression.

Abstract
Based on the disk-halo decomposition method introduced by Persic & Salucci, we use 58 spiral rotation curves to measure the galaxy-background correlation function in the range 3-350 kpc (for H0 = 50 km s-1 Mpc-1). We find that (1) the two-point function is zeta(r) congruent-to (r0/r)1.76, with r0 congruent-to 7 Mpc (for OMEGA-0 = 1), and (2) higher order correlation functions are detected up to the sixth order and are found to fit the hierarchical expression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
