gevolution 2.0: GPU-accelerated relativistic N-body simulations for cosmology
Julian Adamek, Ãyvind Christiansen
High-performance computing is increasingly dominated by hardware acceleration using Graphics Processing Units (GPUs). To take advantage of this long-term trend, we implement a majo…

Cosmic strings, domain walls and environment-dependent clustering
Ãyvind Christiansen, Julian Adamek, Martin Kunz
Recent cosmological data favour phantom-crossing dark energy, motivating models with non-minimal couplings that induce a fifth force on structure formation. Reconciling these model…
