LIGO Lo(g)Normal MACHO: Primordial Black Holes survive SN lensing constraints
Juan Garcia-Bellido, Sebastien Clesse, Pierre Fleury
It has been claimed in Ref.[arXiv:1712.02240] that massive primordial black holes (PBH) cannot constitute all of the dark matter (DM), because their gravitational-lensing imprint o…
Weak gravitational lensing of finite beams
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
The standard theory of weak gravitational lensing relies on the infinitesimal light beam approximation. In this context, images are distorted by convergence and shear, the respecti…
Ray tracing and Hubble diagrams in post-Newtonian cosmology
Viraj A. A. Sanghai, Pierre Fleury, Timothy Clifton
On small scales the observable Universe is highly inhomogeneous, with galaxies and clusters forming a complex web of voids and filaments. The optical properties of such configurati…
