KMT-2022-BLG-1818Lb,c: A Cold Super-Jupiter with a Saturn Sibling

The Astronomical Journal
We present the discovery and analysis of the sixth microlensing two-planet system, KMT-2022-BLG-1818Lb,c, detected by a follow-up program targeting high-magnification events.

The Gaussian-Drude Lens: A Dusty Plasma Model Applicable to Observations Across the Electromagnetic Spectrum

Universe
When radiation from a background source passes through a cloud of cold plasma, diverging lensing occurs if the source and observer are well-aligned. Unlike gravitational lensing, plasma lensing is dispersive, increasing in strength with wavelength.

The Export and Financial Effects of Immigrant Team Composition in International New Ventures

Thunderbird International Business Review, EarlyView.
ABSTRACT Immigrant‐owned international new ventures (INVs) often partner with non‐immigrant entrepreneurs as co‐owners. Their mixed immigrant‐nonimmigrant teams could engender varied perspectives. But it is unclear whether such cognitive diversity improves their international strategy and performance.

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.

Domain Adaptation in Application to Gravitational Lens Finding

The Astrophysical Journal
The next decade is expected to see a tenfold increase in the number of strong gravitational lenses, driven by new wide-field imaging surveys. To discover these rare objects, efficient automated detection methods need to be developed.

Bubbling saddles of the gravitational index

SciPost Physics
We consider the five-dimensional supergravity path integral that computes a supersymmetric index, and uncover a wealth of semiclassical saddles with bubbling topology.

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

Integrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...

Cosmography with the Double-source-plane Strong Gravitational Lens AGEL150745+052256

The Astrophysical Journal
Strong gravitational lenses with two background sources at widely separated redshifts are a promising independent probe of cosmological parameters. We can use these systems, known as double-source-plane lenses (DSPLs), to measure the ratio ( β ) of ...

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.
