Joint velocity and density reconstruction of the Universe with nonlinear differentiable forward modeling
Adrian E. Bayer, Chirag Modi, Simone Ferraro
Reconstructing the initial conditions of the Universe from late-time observations has the potential to optimally extract cosmological information. Due to the high dimensionality of…
Super-sample covariance of the power spectrum, bispectrum, halos, voids, and their cross covariances
Adrian E. Bayer, Jia Liu, Ryo Terasawa +3
We study the effect of super-sample covariance (SSC) on the power spectrum and higher-order statistics: bispectrum, halo mass function, and void size function. We also investigate…
The DESI -body Simulation Project -- II. Suppressing sample variance with fast simulations
Zhejie Ding, Chia-Hsun Chuang, Yu Yu +19
Dark Energy Spectroscopic Instrument (DESI) will construct a large and precise three-dimensional map of our Universe. The survey effective volume reaches $\sim20\Gpchcube$. It is a…
