On the streaming motions of haloes and galaxies
Ravi K. Sheth, Antonaldo Diaferio, Lam Hui +1
A simple model of how objects of different masses stream towards each other as they cluster gravitationally is described. The model shows how the mean streaming velocity of dark ma…
Linear and nonlinear contributions to pairwise peculiar velocities
Ravi K. Sheth, Lam Hui, Antonaldo Diaferio +1
We write the correlation function of dark matter particles, xi(r), as the sum of two terms - one which accounts for nonlinear evolution, and dominates on small scales, and another…
Peculiar velocities of galaxies and clusters
Ravi K. Sheth, Antonaldo Diaferio
We present a simple model for the shape of the distribution function of galaxy peculiar velocities. We show how both nonlinear and linear theory terms combine to produce a distribu…
How Many Galaxies Fit in a Halo? Constraints on Galaxy Formation Efficiency from Spatial Clustering
Roman Scoccimarro, Ravi K. Sheth, Lam Hui +1
We study galaxy clustering using halo models, where gravitational clustering is described in terms of dark matter halos. At small scales, clustering statistics are dominated by hal…
Halo Dark Matter and Ultra-High Energy Cosmic Rays
Pasquale Blasi, Ravi Sheth
The decay of very heavy metastable relics of the Early Universe can produce ultra-high energy cosmic rays (UHECRs) in the halo of our own Galaxy. On distance scales of the order of…
