Making the leap I: Modelling the reconstructed lensing convergence PDF from cosmic shear with survey masks and systematics
Alexandre Barthelemy, Anik Halder, Zhengyangguang Gong +1
The last few years have seen the development of a promising theoretical framework for statistics of the cosmic large-scale structure -- the theory of large deviations (LDT) for mod…
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…
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…
