<i>Euclid</i> preparation: IX. EuclidEmulator2 โ power spectrum emulation with massive neutrinos and self-consistent dark energy perturbations
We present a new, updated version of the EuclidEmulator (called EuclidEmulator2), a fast and accurate predictor for the nonlinear correction of the matter power spectrum. Percent-level accurate emulation is now supported in the eight-dimensional parameter space of $w_0w_a$CDM$+\sum m_\nu$models between redshift $z=0$ and $z=3$ for spatial scales within the range โฆ
