Cosmological Probe Combination for Current and Future Surveys
Andrina Nicola

Abstract:

Recent progress in observational cosmology and the establishment of ΛCDM have relied on the combination of different cosmological probes. These probes are not independent, since they all measure the same physical fields. The resulting cross-correlations allow for a robust test of the cosmological model through the consistency of different physical tracers and for the identification of systematics. Integrated analyses taking into account both the auto- as well as the cross-correlations between probes therefore present a promising analysis method for both current as well as future data.

In this talk, I will present an integrated analysis of CMB temperature anisotropies, CMB lensing, galaxy clustering and weak lensing. I will describe the cosmological probe combination framework as well as the obtained results.

In the last part of the talk, I will present results on photometric galaxy clustering in the Hyper Suprime Cam DR1 data and how these will be used in a forthcoming joint analysis with data from the Atacama Cosmology Telescope.
