The Cosmological -body Code
Lehman H. Garrison, Daniel J. Eisenstein, Douglas Ferrer +2
We present , a fast and accurate cosmological -body code based on a new method for calculating the gravitational potential from a static multipole mesh. The met…
Cosmology with Stacked Cluster Weak Lensing and Cluster-Galaxy Cross-Correlations
Andrés N. Salcedo, Benjamin D. Wibking, David H. Weinberg +4
Cluster weak lensing is a sensitive probe of cosmology, particularly the amplitude of matter clustering and matter density parameter . The main nuisance parameter in a c…
A High-Fidelity Realization of the Euclid Code Comparison -body Simulation with Abacus
Lehman H. Garrison, Daniel J. Eisenstein, Philip A. Pinto
We present a high-fidelity realization of the cosmological -body simulation from the Schneider et al. (2016) code comparison project. The simulation was performed with our Abacu…
The Abacus Cosmos: A Suite of Cosmological N-body Simulations
Lehman H. Garrison, Daniel J. Eisenstein, Douglas Ferrer +3
We present a public data release of halo catalogs from a suite of 125 cosmological -body simulations from the Abacus project. The simulations span 40 CDM cosmologies centered…
Emulating galaxy clustering and galaxy-galaxy lensing into the deeply nonlinear regime: methodology, information, and forecasts
Benjamin D. Wibking, Andrés N. Salcedo, David H. Weinberg +6
The combination of galaxy-galaxy lensing (GGL) with galaxy clustering is one of the most promising routes to determining the amplitude of matter clustering at low redshifts. We sho…
Improving Initial Conditions for Cosmological -Body Simulations
Lehman H. Garrison, Daniel J. Eisenstein, Douglas Ferrer +2
In cosmological -body simulations, the representation of dark matter as discrete "macroparticles" suppresses the growth of structure, such that simulations no longer reproduce l…
