05:09 <galois> [arXiv] “Goku: A 10-Parameter Simulation Suite for Cosmological Emulation” Yanhui Yang, Simeon Bird, Ming-Feng Ho — «We present Goku, a suite of cosmological $N$-body simulations, and the corresponding 10-dimensional emulator, GokuEmu, for the nonlinear matter power spectrum. The simulations span the base parameters of $\Lambda$CDM cosmology and its extensions, including dynamical dark energy ($w_0$, $w_a$), the sum of the…»
