Fisher Forecasting for the DESC with
Paul Rogozenski, Sankarshana Srinivasan, Javier Sánchez +15
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) has begun its ten-year survey of the entire visible southern hemisphere. To ensure robust cosmological measurem…
CoLoRe: fast cosmological realisations over large volumes with multiple tracers
César Ramírez-Pérez, Javier Sanchez, David Alonso +1
We present CoLoRe, a public software package to efficiently generate synthetic realisations of multiple cosmological surveys. CoLoRe can simulate the growth of structure with diffe…
Effects of overlapping sources on cosmic shear estimation: Statistical sensitivity and pixel-noise bias
Javier Sanchez, Ismael Mendoza, David P. Kirkby +1
In Stage-IV imaging surveys, a significant amount of the cosmologically useful information is due to sources whose images overlap with those of other sources on the sky. The cosmic…
Core Cosmology Library: Precision Cosmological Predictions for LSST
Nora Elisa Chisari, David Alonso, Elisabeth Krause +27
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of valid…
A unified pseudo- framework
David Alonso, Javier Sanchez, Anže Slosar
The pseudo- is an algorithm for estimating the angular power and cross-power spectra that is very fast and, in realistic cases, also nearly optimal. The algorithm can be ex…
