Abstract: Robust modeling of non-linear scales is critical for accurate cosmological inference in Stage IV surveys. For weak lensing analyses in particular, a key challenge arises from the incomplete understanding of how non-gravitational processes, such as… read more here.

Abstract: Large-scale structure surveys have reported measurements of the density of matter, Ωm, and the amplitude of clustering, σ8, that are in tension with the values inferred from observations of the cosmic microwave background. While this… read more here.

Abstract: Recent advances in cosmological observations have provided an unprecedented opportunity to investigate the distribution of baryons relative to the underlying matter. In this work, we show that the gas is more extended than the dark… read more here.
