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 light path contribute to the observed images. These additional contributions, known as line-of-sight effects, are non-negligible in practice. This article proposes a new theoretical framework to model the line-of-sight effects, together with very promising applications at the interface of weak and strong lensing. Our… 

Strong lensing time-delay cosmography in the 2020s

Multiply imaged time-variable sources can be used to measure absolute distances as a function of redshifts and thus determine cosmological parameters, chiefly the Hubble Constant

Strong lensing time-delay cosmography in the 2020s

Multiply imaged time-variable sources can be used to measure absolute distances as a function of redshifts and thus determine cosmological parameters, chiefly the Hubble Constant H0. In the two

Time-Delay Cosmography: Measuring the Hubble Constant and other cosmological parameters with strong gravitational lensing

Multiply lensed sources experience a relative time delay in the arrival of photons. This e ff ect can be used to measure absolute distances and the Hubble constant ( H 0 ) and is known as time-delay

Accurate modelling of extragalactic microlensing by compact objects

Microlensing of extragalactic sources, in particular the probability of significant amplifications, is a potentially powerful probe of the abundance of compact objects outside the halo of the Milky

Unveiling the Universe with emerging cosmological probes

The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave Background, Supernovae Type Ia,

Isothermal elliptical gravitational lens models.

Gravitational lens models for observed lensing systems are often based on quasi-elliptical lenses. The use of elliptical mass distributions is motivated by observations of galaxies and by the

Fermat’s Principle

As mentioned in chapter 1, optics and mechanics have a number of analogies which have been used time and again to understand and appreciate concepts in either of the fields. One of the most basic

Line-of-sight effects in strong lensing: putting theory into practice

We present a simple method to accurately infer line of sight (LOS) integrated lensing effects for galaxy scale strong lens systems through image reconstruction. Our approach enables us to separate

Weak gravitational flexion

Flexion is the significant third-order weak gravitational lensing effect responsible for the weakly skewed and arc-like appearance of lensed galaxies. Here we demonstrate how flexion measurements can

Gravitational lenses in arbitrary space-times

The precision reached by current and forthcoming strong-lensing observations requires to accurately model various perturbations to the main deflector. Hitherto, theoretical models have been developed

Cosmic Shear with Einstein Rings

We explore a new technique to measure cosmic shear using Einstein rings. In Birrer et al., we showed that the detailed modeling of Einstein rings can be used to measure external shear to high

Weak lensing distortions beyond shear

When a luminous source is extended, its distortions by weak gravitational lensing are richer than a mere combination of magnification and shear. In a recent work, we proposed an elegant formalism

Cosmic convergence and shear with extended sources

The standard theory of weak gravitational lensing relies on the approximation that light beams are infinitesimal. Our recent work showed that the finite size of sources, and the associated light

Based on the standard gravitational lensing formalism with its e ff ective, projected lensing potential in a given background cosmol-ogy, we investigated under which transformations of the source
