A deconstruction of methods to derive one-point lensing statistics
The Open Journal of AstrophysicsGravitational lensing is a crucial tool for exploring cosmic phenomena, providing insights into galaxy clustering, dark matter, and dark energy. Given the substantial computational demands of $N$-body simulations, approximate methods like $\texttt ...

Ellipticities of Galaxy Cluster Halos from Halo–Shear–Shear Correlations
The Astrophysical JournalWe report the first detection of the halo ellipticities of galaxy clusters by applying the halo–shear–shear correlations (HSSCs), without the necessity of using major axis determination.

Children's agencies navigating sexism and LGBTI+ phobia in Santiago de Chile's primary school
Children &Society, EarlyView.Abstract Through their talk, actions and interactions, children actively shape and develop notions of gender and sexuality. This research delves into the realm of children's agency to explore the ways children act and react to instances of sexism and LGBTI+ phobia.

How Early Trauma Shapes CEO Risk Appetite for Public Debt Versus Bank Debt
Financial Review, EarlyView.ABSTRACT This study examines the impact of CEOs’ early disaster experiences on the choice of debt structure. We find that firms led by CEOs who have endured disasters are more inclined to shift from bank debt to public debt. This evidence remains robust across various alternative measures, empirical specifications, and identification tests aimed at ...

JCMS: Journal of Common Market Studies, EarlyView.Abstract The article presents a model that conceptualizes the discursive construction of post‐disruption dynamics endorsed and reproduced by the affected parties and its potential to (not) contribute to future co‐operation. Conceiving of Brexit as a prime case of a broader phenomenon of post‐disruption contexts, this paper applies this model to the ...

The Astrophysical JournalWe assess the dark matter halo masses of luminous active galactic nuclei (AGNs) over the redshift range 0.2–1.2 using galaxy–galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP).

Self-Gravitating Systems in Extended Gravity
Galaxies, 2014 Starting from the weak field limit, we discuss astrophysical applications of Extended Theories of Gravity where higher order curvature invariants and scalar fields are considered by generalizing the Hilbert-Einstein action linear in the Ricci curvature ...

When Great Powers Struggle: How Geopolitical Alignments of Small States Are Influenced by Their MNEs
Journal of Management Studies, EarlyView.Abstract Comparing two distinct deglobalization periods, this study shows how Finnish multinational enterprises (MNEs) used corporate diplomatic activities (CDA) to influence Finland's alignment with a struggling great power. Drawing from hegemonic stability theory and new institutional economics, we argue that the power's collapsing global networks ...

Forecast of Joint Analysis of Cosmic Shear and Supernovae Magnification from the CSST and LSST
The Astrophysical JournalCosmic shear and cosmic magnification reflect the same gravitational lensing field. Each of these two probes are affected by different systematics. We study the auto- and cross-correlations of cosmic shear from the China Space Survey Telescope and cosmic

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.
