Cosmic Homogeneity: A New Probe
In this presentation we discuss the cosmic homogeneity scale as a new cosmological probe. We review the last decade of the Large Scale Structure investigations on this topic, from the theoretical approach by using fractals to the newest catalogues. We also discuss the difference between a 3D approach and a 2D approach, by specifying what are the radial and angular scale, in order to measure the homogeneity scale from these two approaches. Due to the lack of cosmological model dependence on the 2D approach we show that is possible to use it as a new probe in Cosmology, as well as to find observational results and constraints on cosmological parameters. We also forecast the constraining power of future cosmic homogeneity data, via Monte Carlo simulations, and we obtain competitive constraints on matter density parameters and the Hubble constant from the joint analysis with current SN and BAO measurements.
