Simulations and cosmological inference: A statistical model for power spectra means and covariances
Michael D. Schneider, Lloyd Knox, Salman Habib +3
We describe an approximate statistical model for the sample variance distribution of the non-linear matter power spectrum that can be calibrated from limited numbers of simulations…
Cosmic Calibration: Constraints from the Matter Power Spectrum and the Cosmic Microwave Background
Salman Habib, Katrin Heitmann, David Higdon +2
Several cosmological measurements have attained significant levels of maturity and accuracy over the last decade. Continuing this trend, future observations promise measurements of…
The Halo Mass Function: High-Redshift Evolution and Universality
Zarija Lukic, Katrin Heitmann, Salman Habib +2
We study the formation of dark matter halos in the concordance LCDM model over a wide range of redshifts, from z=20 to the present. Our primary focus is the halo mass function, a k…
Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology
A. E. Evrard, J. Bialek, M. Busha +14
We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result i…
