Cosmology with cosmic web environments I. Real-space power spectra

We undertake the first comprehensive and quantitative real-space analysis of the cosmological information content in the environments of the cosmic web (voids, filaments, walls, and nodes) up to non-linear scales, k=0.5 h/Mpc. Relying on the large …

Cosmology with the kinetic Sunyaev-Zeldovich effect: Independent of the optical depth and sigma 8

The cosmological constraints from the kinetic Sunyaev--Zeldovich experiments are degenerate with the optical depth measurement, which is commonly known as the optical-depth degeneracy. In this work, we introduce a new statistic based on the first …
