Weak Gravitational Lensing by a Sample of X-Ray Luminous Clusters of Galaxies -- II. Comparison with Virial Masses

, 2002
Dynamic velocity dispersion and mass estimates are given for a sample of five X-ray luminous rich clusters of galaxies at intermediate redshifts (z~0.3) drawn from a sample of 39 clusters for which we have obtained gravitational lens mass estimates.

Sociology and The Complexity of What Is Missing

The British Journal of Sociology, EarlyView.
ABSTRACT What is ‘missed’ by sociological literature underpinned by assumptions of presence that a missing approach can rectify? I appropriate a metaphysics of presence and an alternative focus on what is missing as ontological foci to revisit complexity studies in sociology.

Effect of Mask Regions on Weak Lensing Statistics

, 2013
Sky masking is unavoidable in wide-field weak lensing observations. We study how masks affect the measurement of statistics of matter distribution probed by weak gravitational lensing.

First test of Verlinde's theory of emergent gravity using weak gravitational lensing measurements [PDF]

, 2016
Verlinde (2016) proposed that the observed excess gravity in galaxies and clusters is the consequence of Emergent Gravity (EG). In this theory the standard gravitational laws are modified on galactic and larger scales due to the displacement of dark ...

Collective identity and the coalescence of an expert occupational community: The case of the Canadian tax profession

Contemporary Accounting Research, EarlyView.
Abstract Although the community of tax professionals is a key actor in the tax realm, its nature continues to remain elusive in many countries. Using a qualitatively driven mixed‐methods approach that integrates the insights obtained from in‐depth interviews and the results of a survey of practitioners, we examine the Canadian tax field.

The Role of B Corp Certification in Uncertain Times: An Empirical Investigation

Business Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT This paper aims to examine whether B Corp certification enhances firms' ability to navigate uncertain times and how contingent factors affect its effectiveness. Building on Stakeholder Theory and the Resource‐Based View, we formulated a set of research hypotheses and tested them with a long‐term event study and an ordinary least squares ...

Precision Measurement of Large Shear Signals

The Astrophysical Journal Letters
So far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak-lensing science.

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
