Sparsity covariance: a source of uncertainty when estimating correlation functions with a discrete sample of observations in the sky
Pierre Fleury
Cosmological observables rely heavily on summary statistics such as two-point correlation functions. In many practical cases (e.g. the weak-lensing cosmic shear), those correlation…

Line-of-sight effects on double source plane lenses
Daniel Johnson, Thomas Collett, Tian Li +1
Weak gravitational lensing perturbations have a non-negligible impact on strong lensing observables, and several degeneracies exist between the properties of the main lens, line of…
