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…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
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…
