Quasar Milli-lensing and Cold Dark Matter (TNG50) Subhaloes. I. Image Splitting
The Astrophysical JournalWe use numerical mass density profiles from the TNG50 simulation to study the impact of gravitational milli-lensing by dark matter subhaloes on the images of lensed quasars.

Microlensing timescales and flux magnification probabilities of a sample of 204 lensed quasars
Astronomy & AstrophysicsContext. Quasar microlensing is a very useful tool in cosmology and astrophysics, as well as a source of uncertainty in certain investigations, such as the determination of the Hubble constant from lensed quasars.

Journal of the Association for Information Science and Technology, EarlyView.Abstract Cross‐disciplinary research is a priority for many academic institutions, with a growing body of scholarship dedicated to studying the central practice of cross‐disciplinarity: integration, or the synthesis of knowledge, information, and data across disciplines and domains.

Strong gravitational lensing’s ‘external shear’ is not shear
Monthly Notices of the Royal Astronomical SocietyABSTRACT The distribution of mass in galaxy-scale strong gravitational lenses is often modelled as an elliptical power-law plus ‘external shear’, which notionally accounts for neighbouring galaxies and cosmic shear along our line of sight.

Strong Gravitational Lensing: Bright Galaxies & Lost Dark-Matter [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractGravitational lensing and stellar dynamics provide two complementary methods to probe the smooth and clumpy stellar and dark-matter mass distribution in early-type galaxies, currently already over a range of two orders of magnitude in virial mass, more than ten orders of magnidude in dynamic mass range in each galaxy (i.e.

Dynamical Systematics for Time-delay Lenses and the Impact on the Hubble Constant
The Astrophysical JournalWhile time-delay lenses can independently probe H _0 , the estimates are degenerate with the convergence of the lens near the Einstein radius. Velocity dispersions, σ , can be used to break the degeneracy, with uncertainties Δ H / H _0 ∝ Δ σ ^2 / σ ^2 ...

British Educational Research Journal, EarlyView.Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

British Educational Research Journal, EarlyView.Abstract Curriculum decolonisation has become a prominent feature of equity agendas in UK higher education, yet there remains limited empirical and theoretical work on how such initiatives are evaluated, particularly within business schools. This paper presents one of the first multi‐institutional empirical studies examining how UK business schools ...

Gravitational Lensing: Strong, Weak and Micro
, 2006 The theory, observations, and applications of gravitational lensing constitute one of the most rapidly growing branches of astrophysics. The gravitational deflection of light generated by mass concentrations along a light path produces magnification ...
