Generating Dark Matter Subhalo Populations Using Normalizing Flows

The Open Journal of Astrophysics
Strong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.

Black hole tidal charge constrained by strong gravitational lensing

, 2013
Spherically symmetric brane black holes have tidal charge, which modifies both weak and strong lensing characteristics. Even if lensing measurements are in agreement with a Schwarzschild lens, the margin of error of the detecting instrument allows for a ...

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.

Precision MARS Mass Reconstruction of A2744: Synergizing the Largest Strong-lensing and Densest Weak-lensing Data Sets from JWST

The Astrophysical Journal
We present a new high-resolution free-form mass model of A2744 that combines both weak-lensing (WL) and strong-lensing (SL) data sets from JWST. The SL data set comprises 286 multiple images, presenting the most extensive SL constraint to date for a ...

Cluster Reconstruction from Combined Strong and Weak Lensing [PDF]

, 1999
The lensing information provided by multiple images, arclets, and statistical distortions can all be formulated as linear constraints on the arrival-time surface, and hence on the mass distribution.

A Systematic Review of Strong Gravitational Lens Modeling Software

, 2013
Despite expanding research activity in gravitational lens modeling, there is no particular software which is considered a standard. Much of the gravitational lens modeling software is written by individual investigators for their own use.

Change in migrants’ political attitudes: Acculturation and cosmopolitanization

American Journal of Political Science, EarlyView.
Abstract This paper investigates change in international migrants’ political attitudes. It theorizes a novel attitudinal typology distinguishing polity‐specific attitudes influenced by national contexts and transnational attitudes forged by migratory experience. It applies the typology to four dimensions of political competition in contemporary Europe:
