Abstract: We present a new analytic calculation for the redshift-space evolution of the one-point galaxy probability distribution function (PDF). The non-linear evolution of the matter density field ...

What Is A Probability Density Function? A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable ...

A Probability Density Function (PDF) helps identify the regions in the distribution where observations are more likely to occur, in other words, where the observation occurrence is more dense. It is ...

Abstract: We use the physics of ellipsoidal collapse to model the probability distribution function (PDF) of the smoothed dark matter density field in real and redshift space. We provide a simple ...

We present a new analytic calculation for the redshift-space evolution of the 1-point galaxy Probability Distribution Function (PDF). The nonlinear evolution of the matter density field is treated by ...

We use the probability distribution function (PDF) of the lya forest flux at z=2-3, measured from high-resolution UVES/VLT data, and hydrodynamical simulations to obtain constraints on cosmological ...
