The nonlinear probability distribution function in models with local primordial non-Gaussianity
Tsz Yan Lam, Ravi K. Sheth
We use the spherical evolution approximation to investigate nonlinear evolution from the non-Gaussian initial conditions characteristic of the local f_nl model. We provide an analy…
Ellipsoidal collapse and the redshift space probability distribution function of dark matter
Tsz Yan Lam, Ravi K. Sheth
We use the physics of ellipsoidal collapse to model the probability distribution function of the smoothed dark matter density field in real and redshift space. We provide a simple…
The 2dF-SDSS LRG and QSO survey: evolution of the clustering of luminous red galaxies since z = 0.6
David A. Wake, Ravi K. Sheth, Robert C. Nichol +17
We present an analysis of the small-to-intermediate scale clustering of samples of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey and the 2dF-SDSS LRG and QSO (2SLA…
Perturbation theory and excursion set estimates of the probability distribution function of dark matter, and a method for reconstructing the initial distribution function
T. Y. Lam, R. K. Sheth
Nonlinear evolution can sometimes be modelled by a deterministic mapping from initial to final of the local smoothed overdensity. Perturbation theory methods base on this determini…
