Persistent fluctuations in the distribution of galaxies from the Two degree Field Galaxy Redshift Survey

Understand

We apply the scale-length method to several three dimensional samples of the Two degree Field Galaxy Redshift Survey.

• This method allows us to map in a quantitative and powerful way large scale structures in the distribution of galaxies controlling systematic effects.
• By determining the probability density function of conditional fluctuations we show that large scale structures are quite typical and correspond to large fluctuations in the galaxy density field.
• We do not find a convergence to homogeneity up to the samples sizes, i.e.
