Beyond 32-point cosmology: the integrated shear and galaxy 3-point correlation functions
Anik Halder, Zhengyangguang Gong, Alexandre Barreira +3
We present the integrated 3-point correlation functions (3PCF) involving both the cosmic shear and the galaxy density fields. These are a set of higher-order statistics that descri…
DES Y3 + KiDS-1000: Consistent cosmology combining cosmic shear surveys
Dark Energy Survey, Kilo-Degree Survey Collaboration, : +160
We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the Kilo-Degree Survey (KiDS-1000) in a collaborative effort between the two survey teams. We find c…
Cosmology from the integrated shear 3-point correlation function: simulated likelihood analyses with machine-learning emulators
Zhengyangguang Gong, Anik Halder, Alexandre Barreira +2
The integrated shear 3-point correlation function measures the correlation between the local shear 2-point function and the 1-point shear aperture mass in patch…
