Cosmic shear with Einstein rings
Pierre Fleury
Cosmic shear is a key probe of modern cosmology. Amongst its challenges are shape noise and intrinsic alignments, both due to our ignorance of the unlensed shape of the source gala…
Emergent Cosmological Expansion in Scalar-Tensor Theories of Gravity
Chad Briddon, Timothy Clifton, Pierre Fleury
We consider the emergence of large-scale cosmological expansion in scalar-tensor theories of gravity. This is achieved by modelling sub-horizon regions of space-time as weak-field…
Weak lensing of strong lensing: beyond the tidal regime
Théo Duboscq, Natalie B. Hogg, Pierre Fleury +1
The analysis of strong lensing images usually involves an external convergence and shear, which are meant to model the effect of perturbations along the line of sight, on top of th…
Foreground biases in strong gravitational lensing
Daniel Johnson, Pierre Fleury, Julien Larena +1
Strong gravitational lensing is a competitive tool to probe the dark matter and energy content of the Universe. However, significant uncertainties can arise from the choice of lens…
