The theory of stochastic cosmological lensing

, 2015
On the scale of the light beams subtended by small sources, e.g. supernovae, matter cannot be accurately described as a fluid, which questions the applicability of standard cosmic lensing to those cases.

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 ...

A study of stable wormhole solution with non-commutative geometry in the framework of linear $$f(R,{\mathcal {L}}_m, T)$$ f ( R , L m , T ) gravity

European Physical Journal C: Particles and Fields
This research delves into the potential existence of traversable wormholes (WHs) within the framework of modified, curvature based gravity. The modification includes linear perturbations of the matter Lagrangian and the trace of the energy-momentum ...

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.

Analytical shear and flexion of Einasto dark matter haloes [PDF]

, 2012
N-body simulations predict that dark matter haloes are described by specific density profiles on both galactic- and cluster-sized scales. Weak gravitational lensing through the measurements of their first and second order properties, shear and flexion ...

Coupled Geodynamical‐Geochemical Perspectives on the Generation and Composition of Mid‐Ocean Ridge Basalts

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 2, February 2024.
Abstract Owing to their abundance and relative availability on Earth's seafloor, mid‐ocean ridge basalts (MORBs) have a well‐defined chemical element budget, reflected by the low standard deviation associated with typical normal MORB (N‐MORB) composition. However, the exact mechanisms leading to magma differentiation and MORB generation remain debated,

Twisting shadows: Light rings, lensing, and shadows of black holes in swirling universes [PDF]

Physical Review D
Using the Ernst formalism, a novel solution of vacuum general relativity (GR) was recently obtained [1], describing a Schwarzschild black hole (BH) immersed in a nonasymptotically flat rotating background, dubbed swirling universe, with the peculiar ...

Evolution of intrinsic ellipticity correlations due to peculiar motion

, 2012
Topic of this paper is the time-evolution of intrinsic correlations of galaxy ellipticities due to peculiar motion. In our model, the galaxy ellipticities are determined from the angular momentum of their host haloes, which can be computed from the ...

Angular ellipticity correlations in a composite alignment model for elliptical and spiral galaxies and inference from weak lensing

, 2018
We investigate a physical, composite alignment model for both spiral and elliptical galaxies and its impact on cosmological parameter estimation from weak lensing for a tomographic survey. Ellipticity correlation functions and angular ellipticity spectra

Modeling CMB Lensing Cross Correlations with {\sc CLEFT}

, 2017
A new generation of surveys will soon map large fractions of sky to ever greater depths and their science goals can be enhanced by exploiting cross correlations between them.
