The inner mass power spectrum of galaxies using strong gravitational lensing: beyond linear approximation [PDF]
In the last decade, the detection of individual massive dark matter sub-haloes has been possible using potential correction formalism in strong gravitational lens imaging.

A Smithian Political Economy Approach for the Competition Law of the 21st Century
This study aims to show how a Smithian political economy approach could assist competition law in addressing the challenges of the 21st‐century economy. We revisit Smith's Wealth of Nations to provide a more nuanced understanding of his views, contrasting them with the prevailing libertarian interpretation called here ‘Chicago Smith’.

Strong field limit analysis of gravitational retro-lensing
We present a complete treatment in the strong field limit of gravitational retro-lensing by a static spherically symmetric compact object having a photon sphere.

INHERITANCE AND INCEST: TOWARD A LÉVI‐STRAUSSIAN READING OF MONTESQUIEU'S DE L'ESPRIT DES LOIS1
ABSTRACT The premise of this article is that Montesquieu, while seen as an Enlightenment thinker who contributed centrally to the development of the social sciences before the period of discipline formation in the nineteenth century, is generally appreciated in only the vaguest of terms.

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 be used to measure galaxy halo density profiles and ...

Recent Developments in Degenerate Higher Order Scalar Tensor Theories
Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

Statistical uncertainties and systematic errors in weak lensing mass estimates of galaxy clusters [PDF]
Upcoming and ongoing large area weak lensing surveys will also discover large samples of galaxy clusters. Accurate and precise masses of galaxy clusters are of major importance for cosmology, for example, in establishing well calibrated observational ...

Abstract Some philosophical pluralists argue that a top‐down and a bottom‐up approach serve as equally justified methods for engaging in ontological inquiry. In the top‐down approach, we start with an analysis of theory and extrapolate from there to the world.

An accurate and practical method for inference of weak gravitational lensing from galaxy images [PDF]
We demonstrate highly accurate recovery of weak gravitational lensing shear using an implementation of the Bayesian Fourier Domain (BFD) method proposed by Bernstein & Armstrong (2014, BA14), extended to correct for selection biases. The BFD formalism is

Seeking Languagelessness: Maker Literacies Mindsets to Disrupt Normative Practices
This article challenges an over‐reliance on language as the primary means to communicate knowledge by adopting a languagelessness approach to maker pedagogies and maker literacies. Having conducted makerspace and design‐based research for some time, we separately and together noticed a productive relationship between wordless relational makerspace and ...
