Forecasting the Detection of Lyman-alpha Forest Weak Lensing from the Dark Energy Spectroscopic Instrument and Other Future Surveys

The Open Journal of Astrophysics
The apparent angular positions of quasars are deflected on the sky by the gravitational field sourced by foreground matter. This weak lensing effect is measurable through the distortions it introduces in the lensed quasar spectra.

Probing a regular non-minimal Einstein-Yang-Mills black hole with gravitational lensings

Physics Letters B, 2019
We investigate weak and strong deflection gravitational lensings of the regular black hole predicted by a non-minimal Einstein–Yang–Mills theory. We find that its weak deflection lensing is the same as a Reissner–Nordström black hole's.

A deconstruction of methods to derive one-point lensing statistics

The Open Journal of Astrophysics
Gravitational 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 ...

Classroom boundaries and teacher agency: Challenges of implementing Ireland's new primary curriculum

The Curriculum Journal, EarlyView.
Abstract This article reports on a doctoral study examining teacher agency in one Irish primary school at a timely moment ahead of the implementation of the new Primary Curriculum Framework in September 2025. The framework embeds teacher agency as a central professional principle, yet findings from this study reveal a more cautious and bounded reality.

Gravitational lensing by a dark compact object in modified gravity and observational constraints from Einstein rings

European Physical Journal C: Particles and Fields
In this manuscript, we provide a comprehensive study of gravitational lensing by dark compact objects predicted by modified gravity (MOG) based on the scalar–vector–tensor action, with the aim of providing new insights into the nature of gravitational ...

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...
