Cosmology with the line-of-sight shear of strong gravitational lenses

Pierre Fleury, Daniel Johnson, Théo Duboscq +2

Stage-IV photometric galaxy surveys are designed to measure the position and shapes of billions of galaxies. Their aim is to characterise the large-scale distribution of matter in…

Line-of-sight shear in SLACS strong lenses II: validation tests with an extended sample

Natalie B. Hogg, Daniel P. Johnson, Anowar J. Shajib +1

Strong gravitational lensing images are subject to shape distortions due to inhomogeneities along the line of sight. The leading order shape distortion is shear, which, if measurab…

Probing the Cosmological Principle with CMB lensing and cosmic shear

James Adam, Roy Maartens, Julien Larena +2

The standard cosmological model assumes the Cosmological Principle. However, recent observations hint at possible violations of isotropy on large scales, possibly through late-time…

Line-of-sight shear in SLACS strong lenses I: shear and mass model parametrisations

Natalie B. Hogg, Daniel P. Johnson, Anowar J. Shajib +1

Inhomogeneities along the line of sight in strong gravitational lensing distort the images produced, in an effect called shear. If measurable, this shear may provide independent co…

Probing the Cosmological Principle with weak lensing shear

James Adam, Roy Maartens, Julien Larena +1

The Cosmological Principle is a cornerstone of the standard model of cosmology and shapes how we view the Universe and our place within it. It is imperative, then, to devise multip…

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…
