Title: “Constraining cosmology and astrophysics using the combination of CMB x LSS, and understanding biases in cross-correlation measurements”
Abstract:
Cross-correlation measurements between CMB and LSS observables is becoming an increasingly popular approach to constrain cosmology and astrophysics. Since CMB and LSS surveys have different experimental systematic effects, cross-correlation measurements are known to be minimally impacted by these effects. However, what is often disregarded are the astrophysical systematic effects, which are present in both CMB and LSS data, which contaminate cross-correlation measurements. In the first part of the talk, I will present the recent results from the DESxSPT 6x2pt analysis and discuss how we mitigated such biases. In the second part of the talk, I will present a new simulation suite that has both CMB and LSS observables that can be used to study these biases.
