An accurate and practical method for inference of weak gravitational lensing from galaxy images [PDF]
, 2015 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

Metaphilosophy, Volume 56, Issue 1, Page 35-51, January 2025.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.

Light bending and gravitational lensing in Brans-Dicke theory
Physics Letters B, 2019 As an important candidate theory of gravity, Brans-Dicke theory has been widely studied. In this paper, we investigate light bending and gravitational lensing by compact objects in Brans-Dicke theory in weak gravitational field.

Describing variations of the Fisher-matrix across parameter space
, 2016 Forecasts in cosmology, both with Monte-Carlo Markov-chain methods and with the Fisher matrix formalism, depend on the choice of the fiducial model because both the signal strength of any observable as well as the model nonlinearities linking observables

Seeking Languagelessness: Maker Literacies Mindsets to Disrupt Normative Practices
Reading Research Quarterly, Volume 59, Issue 3, Page 298-312, July/August/September 2024.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 ...

Gravitational lensing in modified Newtonian dynamics
, 2001 Modified Newtonian dynamics (MOND) is an alternative theory of gravity that aims to explain large-scale dynamics without recourse to any form of dark matter.

Viscosity Measurements at High Pressures: A Critical Appraisal of Corrections to Stokes' Law
Journal of Geophysical Research: Solid Earth, Volume 129, Issue 5, May 2024.Abstract Fluids and melts in planetary interiors significantly influence geodynamic processes from volcanism to global‐scale differentiation. The roles of these geofluids depend on their viscosities (η). Constraining geofluid η at relevant pressures and temperatures relies on laboratory‐based measurements and is most widely done using Stokes' Law ...

, 2005 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 ...

The View from the Top: Visual Intrusion as Nuisance in Fearn v Tate Gallery
The Modern Law Review, Volume 87, Issue 3, Page 697-714, May 2024.In Fearn v Board of Trustees of the Tate Gallery the UK Supreme Court unanimously held that visual intrusions are in principle actionable under the tort of private nuisance. On the facts, a narrow 3:2 majority found that the Tate Modern was liable for the operation of its viewing gallery where the public could see into the claimants’ flats.

Primordial black holes from axion domain wall collapse
Journal of High Energy PhysicsThe QCD axion can solve the Strong CP Problem and be the dark matter of our universe. If the PQ symmetry breaking scale associated with the axion is below the inflationary reheating temperature, axion strings and domain walls populate the universe.
