Residual Test to Search for Microlensing Signatures in Strongly Lensed Gravitational Wave Signals

The Astrophysical Journal
When a gravitational wave signal encounters a massive object, such as a galaxy or galaxy cluster, it undergoes strong gravitational lensing, producing multiple copies of the original signal.

Cosmological Model-independent Constraints on Spatial Curvature from Strong Gravitational Lensing and SN Ia Observations

Astrophysical Journal, 2019
Applying the distance sum rule in strong gravitational lensing (SGL) and SN Ia observations, one can provide an interesting cosmological model-independent method to determine the cosmic curvature parameter Ωk.

Cosmology using Strong Gravitational Lensing

, 2023
The light we observe from distant astrophysical objects including supernovae and quasars allows us to determine large distances in terms of a cosmological model. Despite the success of the standard cosmological model in fitting the data, there remains no underlying explanation for the accelerated expansion and dark matter.

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.

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:

A Novel Test for MOND: Gravitational Lensing by Disk Galaxies

The Astrophysical Journal
Disk galaxies represent a promising laboratory for the study of gravitational physics, including alternatives to dark matter (DM), owing to the possibility of coupling rotation curves’ dynamical data with strong gravitational lensing (SGL) observations ...

Aspirations‐Capabilities of School‐to‐Work Transition in a Migratory Context: A Case of Thai Tertiary‐Level Migrants in Taiwan

Asia Pacific Viewpoint, EarlyView.
ABSTRACT This article explores aspirations‐capabilities of Thai migrants who transitioned from tertiary education to employment in Taiwan. Drawing on semi‐structured interviews with 23 Thai migrants, this study unpacks three distinct mobility trajectories under a processual perspective.

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.
