A forward modeling approach to analyzing galaxy clustering with SimBIG

PNAS 120, 42 (2023)

We present the SimBIG framework and apply it to analyze the power spectrum of SDSS-III: BOSS CMASS galaxies. We demonstrate that we can rigorously analyze galaxy clustering down to non-scales (k=0.5 h/Mpc) and extract additional cosmological information beyondc current standard anlayses.

SimBIG: mock challenge for a forward modeling approach to galaxy clustering

JCAP 2023, 4 (2022)

We present the mock challenge used to validate the SimBIG framework. The mock challenge consists of 1,500 test simulations constructed using forward models with different N-body simulation, halo finder, and galaxy-halo connection. With these simulations, we rigorously validate the accuarcy and precision of the posteriors inferred from SimBIG
