The Halo Mass Function from Excursion Set Theory with a Non-Gaussian Trispectrum
A sizeable level of non-Gaussianity in the primordial cosmological perturbations may be induced by a large trispectrum, i.e. by a large connected four-point correlation function. We compute the effect of a primordial non-Gaussian trispectrum on the halo mass function, within excursion set theory. We use the formalism that we have developed in a previous series of papers and which allows us to t...
متن کاملThe Halo Mass Function from the Excursion Set Method. Iii. First Principle Derivation for Non-gaussian Theories
The high-mass tail of the dark matter halo mass function may be a sensitive probe of primordial nonGaussianities. In this paper, which is the third of a series of three, we perform a first-principle computation of the effect of primordial non-Gaussianity on the halo mass function using the excursion set method, where the evolution of the density perturbation with the smoothing scale is stochast...
متن کاملThe Halo Mass Function from the Excursion Set Method. I. First Principle Derivation for the Non-markovian Case of Gaussian Fluctuations and Generic Filter
A classic method to compute the mass function of dark matter halos is the excursion set method, where the density perturbation evolves stochastically with the smoothing scale, and the problem of computing the probability of halo formation is mapped into the so-called first-passage time problem in the presence of a barrier. To date, however, analytical results were only obtained if the density p...
متن کاملThe Halo Mass Function from the Excursion Set Method. Ii. the Diffusing Barrier
This paper is the second of a series of three where we study the mass function of virialized dark matter halos using the excursion set method. Motivated by recent large-scale N-body simulations determining the relation between the density threshold for gravitational collapse and the variance of the linear density field for regions that collapse to form halos by the present epoch, we deduce that...
متن کاملNon–gaussian Fluctuations from Textures
One of the most powerful tools to probe the existence of cosmic defects in the early universe is through the Cosmic Microwave Background (CMB) radiation. It is well known that computations with causal sources are more involved than the adiabatic counterparts based on inflation, and this fact has in part hampered the development of fine detailed predictions. Analytical modeling, while necessaril...
