FAST-PT II: an algorithm to calculate convolution integrals of general tensor quantities in cosmological perturbation theory
Xiao Fang, Jonathan A. Blazek, Joseph E. McEwen +1
Cosmological perturbation theory is a powerful tool to predict the statistics of large-scale structure in the weakly non-linear regime, but even at 1-loop order it results in compu…
FAST-PT: a novel algorithm to calculate convolution integrals in cosmological perturbation theory
Joseph E. McEwen, Xiao Fang, Christopher M. Hirata +1
We present a novel algorithm, FAST-PT, for performing convolution or mode-coupling integrals that appear in nonlinear cosmological perturbation theory. The algorithm uses several p…
The effects of assembly bias on cosmological inference from galaxy-galaxy lensing and galaxy clusters
Joseph E. McEwen, David H. Weinberg
The combination of galaxy-galaxy lensing (GGL) and galaxy clustering is a promising route to measuring the amplitude of matter clustering and testing modified gravity theories of c…
