Measuring line-of-sight shear with Einstein rings: a proof of concept
Natalie B. Hogg, Pierre Fleury, Julien Larena +1
Line-of-sight effects in strong gravitational lensing have long been treated as a nuisance. However, it was recently proposed that the line-of-sight shear could be a cosmological o…
Euclid: Testing the Copernican principle with next-generation surveys
D. Camarena, V. Marra, Z. Sakr +112
The Copernican principle, the notion that we are not at a special location in the Universe, is one of the cornerstones of modern cosmology and its violation would invalidate the Fr…
Dancing in the dark: detecting a population of distant primordial black holes
Matteo Martinelli, Francesca Scarcella, Natalie B. Hogg +3
Primordial black holes (PBHs) are compact objects proposed to have formed in the early Universe from the collapse of small-scale over-densities. Their existence may be detected fro…
Accurate modelling of extragalactic microlensing by compact objects
Víctor Boscá, Pierre Fleury, Juan García-Bellido
Microlensing of extragalactic sources, in particular the probability of significant amplifications, is a potentially powerful probe of the abundance of compact objects outside the…
Euclid: Forecast constraints on consistency tests of the CDM model
S. Nesseris, D. Sapone, M. Martinelli +112
The standard cosmological model is based on the fundamental assumptions of a spatially homogeneous and isotropic universe on large scales. An observational detection of a violation…
Line-of-sight effects in strong gravitational lensing
Pierre Fleury, Julien Larena, Jean-Philippe Uzan
While most strong-gravitational-lensing systems may be roughly modelled by a single massive object between the source and the observer, in the details all the structures near the l…
