Unmasking the Masked Universe: the 2M++ catalogue through Bayesian eyes

Understand

This work describes a full Bayesian analysis of the Nearby Universe as traced by galaxies of the 2M++ survey.

• The analysis is run in two sequential steps.
• The first step self-consistently derives the luminosity dependent galaxy biases, the power-spectrum of matter fluctuations and matter density fields within a Gaussian statistic approximation.
• The second step makes a detailed analysis of the three dimensional Large Scale Structures, assuming a fixed bias model and a fixed cosmology.
