Forecast of Joint Analysis of Cosmic Shear and Supernovae Magnification from the CSST and LSST

open access: yesThe Astrophysical Journal
Cosmic 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

Unpacking Merit, Fit, and Diversity: A Multifaceted Framework to Academic Gatekeeping in Social Sciences at U.S. R1 Research Universities

open access: yesSociological Inquiry, EarlyView.
This study draws on interviews with 50 sociology and business professors across two private and five public American universities, and proposes a novel “Merit‐Fit‐Diversit” framework to show how narratives of merit, fit, and diversity emerge at different evaluation stages of tenure‐track job candidates. The evaluation produces inequality because: merit

Weak Lensing Analysis of A2390 Using Short Exposures

open access: yesThe Astrophysical Journal
We present a weak lensing analysis of the galaxy cluster A2390 at z = 0.23 using second moment shape measurements made in 411 short 60 s exposures. The exposures are obtained in three broadband photometric filters ( g , r , and i ) using WIYN-ODI.

Light bending and gravitational lensing in Brans-Dicke theory

open access: yesPhysics Letters B, 2019
As an important candidate theory of gravity, Brans-Dicke theory has been widely studied. In this paper, we investigate light bending and gravitational lensing by compact objects in Brans-Dicke theory in weak gravitational field.

Finding Stars: Mapping the Geography of the World's Scientific Elites

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract Scientific excellence is clustering ever more tightly in a few ‘superstar’ cities. Four—New York, Boston, London and the San Francisco Bay Area—now host 12% of the world's top scientists. In contrast, the Global South remains largely absent, with the notable exception of Beijing's dramatic rise.

Becoming inclusive: Developing pre‐service teachers' orientations towards their practice in Scotland

open access: yesThe Curriculum Journal, Volume 37, Issue 1, Page 43-60, March 2026.
Abstract This article presents findings, from a case study with a cohort of third‐year undergraduate pre‐service teachers (PSTs) in Scotland, regarding their ideas about inclusion and curricular justice, as they concurrently encountered practice and theory.

Dark Matter Halos of Luminous Active Galactic Nuclei from Galaxy–Galaxy Lensing with the HSC Subaru Strategic Program

open access: yesThe Astrophysical Journal
We 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).
