A High-Fidelity Realization of the Euclid Code Comparison $N$-body Simulation with Abacus

Understand

We present a high-fidelity realization of the cosmological $N$-body simulation from the Schneider et al.

• (2016) code comparison project.
• The simulation was performed with our Abacus $N$-body code, which offers high force accuracy, high performance, and minimal particle integration errors.
• The simulation consists of $2048^3$ particles in a $500\ h^{-1}\mathrm{Mpc}$ box, for a particle mass of $1.2\times 10^9\ h^{-1}\mathrm{M}_\odot$ with $10\ h^{-1}\mathrm{kpc}$ spline softening.
