Large-scale
Distribution of Galaxies
•w(θ) isn’t so hard to
measure from various surveys – just need positions.
• ξ(r) is harder – must
have redshifts to do properly.
Can make some assumptions however.
•Observationally verified
parameterization works for scales of 100 h-1 kpc to 10 h-1 Mpc, and you
get r0
= 5 h-1 Mpc and γ = 1.8. Note use of “h”.
