Mitigation of nonlinear galaxy bias with a theoretical-error likelihood
Abdias Aires, Nickolas Kokron, Rogerio Rosenfeld +2
Stage-IV galaxy surveys will measure correlations at small cosmological scales with high signal-to-noise ratio. One of the main challenges of extracting information from small scal…
