Toward a halo mass function for precision cosmology: the limits of universality
Jeremy L Tinker, Andrey V Kravtsov, Anatoly Klypin +5
We measure the mass function of dark matter halos in a large set of collisionless cosmological simulations of flat LCDM cosmology and investigate its evolution at z<~2. Halos are i…
Peculiar Velocities into the Next Generation: Cosmological Parameters From Large Surveys without Bias from Nonlinear Structure
Alexandra Abate, Sarah Bridle, Luis F. A. Teodoro +2
We investigate methods to best estimate the normalisation of the mass density fluctuation power spectrum (sigma_8) using peculiar velocity data from a survey like the Six degree Fi…
The Cosmic Code Comparison Project
Katrin Heitmann, Zarija Lukic, Patricia Fasel +11
Current and upcoming cosmological observations allow us to probe structures on smaller and smaller scales, entering highly nonlinear regimes. In order to obtain theoretical predict…
Close Pairs as Proxies for Galaxy Cluster Mergers
Andrew R. Wetzel, A. E. Schulz, Daniel E. Holz +1
Galaxy cluster merger statistics are an important component in understanding the formation of large-scale structure. Unfortunately, it is difficult to study merger properties and e…
Simulations of Baryon Oscillations
Eric Huff, A. E. Schulz, Martin White +2
The coupling of photons and baryons by Thomson scattering in the early universe imprints features in both the Cosmic Microwave Background (CMB) and matter power spectra. The former…
The Clustering of Massive Halos
Andrew R. Wetzel, J. D. Cohn, Martin White +2
The clustering properties of dark matter halos are a firm prediction of modern theories of structure formation. We use two large volume, high-resolution N-body simulations to study…
