Cosmography with strong lensing of LISA gravitational wave sources [PDF]

open access: yes, 2011
LISA might detect gravitational waves from mergers of massive black hole binaries strongly lensed by intervening galaxies (Sereno et al. 2010). The detection of multiple gravitational lensing events would provide a new tool for cosmography.

Harnessing the Interfacial Activity of Soluble Faba Protein‐Tannic Acid Conjugates for Enhanced Lipid Oxidative Stability of Oil‐in‐Water Emulsions

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In oil‐in‐water emulsions, lipid oxidation begins at the interface between the two phases. One strategy to slow down this process is to place antioxidants at the interface, where they can directly block oxidative reactions. This study explored that idea by conjugating soluble faba bean protein with tannic acid using the free‐radical grafting ...

Reconstruction of Gravitational Lensing Using WMAP 7-Year Data

open access: yes, 2011
Gravitational lensing by large scale structure introduces non-Gaussianity into the Cosmic Microwave Background and imprints a new observable, which can be used as a cosmological probe. We apply a four-point estimator to the Wilkinson Microwave Anisotropy

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Microlensing-Based Studies of the Unresolved Structure of AGNs and the Composition of Lensing Galaxies

open access: yesOpen Astronomy, 2011
Multiple images of quasars formed by gravitational lensing are typically seen through the lensing galaxy. The granulation of the galaxy in stars or other compact objects induces local (‘microscopic’) but strong fluctuations in the gravitational potential

The Scales of Gravitational Lensing

open access: yesUniverse, 2016
After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating in astrophysics and cosmology.

Lensing in the Blue. II. Estimating the Sensitivity of Stratospheric Balloons to Weak Gravitational Lensing

open access: yesThe Astronomical Journal, 2023
The Superpressure Balloon-borne Imaging Telescope ( SuperBIT ) is a diffraction-limited, wide-field, 0.5 m, near-infrared to near-ultraviolet observatory designed to exploit the stratosphere’s space-like conditions.

A gamified formative question bank to enhance student learning and engagement in a foundational medical science course

open access: yesAnatomical Sciences Education, EarlyView.
Abstract While gamified learning platforms show promise for engaging digital learners and promoting active learning, evidence of their effectiveness in predicting academic outcomes remains limited. This study examined how engagement patterns and incentives impact academic outcomes in a gamified environment to determine whether a formative question bank

Mapping the 3-D Dark Matter potential with weak shear

open access: yes, 2002
We investigate the practical implementation of Taylor's (2002) 3-dimensional gravitational potential reconstruction method using weak gravitational lensing, together with the requisite reconstruction of the lensing potential.
