Weak Gravitational Lensing Uncertainties
, 2011 Dark matter dominates the mass distribution of the universe, and dark energy determines its expansion. The two are the most mysterious and attractive subjects in modern cosmology, because they provide an opportunity to discover new fundamental physics.

The Astrophysical Journal Supplement SeriesWe present the result of a comparison between the dark matter distribution inferred from weak gravitational lensing and the observed galaxy distribution to identify dark structures with a high dark-matter-to-galaxy density ratio.

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The Mars 2020 mission has explored depositional environments recorded in a fan‐shaped deposit on the western side of Jezero crater. Kodiak butte is an isolated outcrop of sedimentary rock ∼1 km south of the western fan scarp and may be an erosional remnant of said fan.

Alternative estimators for weak gravitational lensing
, 2012 Weak gravitational lensing provides a means to measure the total mass in the Universe. The incoming light from distant galaxies is disturbed by the inhomogeneity of the dark matter distribution along the line of sight. The correlations of shape in an observed galaxy population can be used to probe the total mass density fluctuations in the Universe ...

Gravitational lensing derives its simplicity from some basic assumptions that are satisfied by most physical situations.The thin lens approximation and weak field approximations were used to build the whole theory and explain the phenomenology up to ...

The Astrophysical JournalWe present a new high-resolution free-form mass model of A2744 that combines both weak-lensing (WL) and strong-lensing (SL) data sets from JWST. The SL data set comprises 286 multiple images, presenting the most extensive SL constraint to date for a ...

Varying hydraulic strategies within leaves, stems and roots of coexisting desert shrubs
Functional Ecology, Volume 40, Issue 10, Page 3276-3295, October 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Effective and continuous root‐to‐leaf hydraulic transport is crucial for plant survival and growth during drought. However, the capacity to resist hydraulic dysfunction remains understudied in leaves and roots, especially for desert shrubs.

The Effect of Intrinsic Alignments on Weak-lensing Statistics in Hydrodynamical Simulations
The Astrophysical JournalThe next generation of weak-gravitational-lensing surveys has the potential to place stringent constraints on cosmological parameters. However, their analysis is limited by systematics such as the intrinsic alignments of galaxies, which alter weak ...

The humanitarian–development–peace (triple) nexus: a typology and critical reflections
Disasters, Volume 50, Issue 4, October 2026.Abstract This article explores how the humanitarian–development–peace (HDP) nexus (also known as the triple nexus) is operationalised, moving beyond policy discourse to implementation on the ground. Drawing on a systematic literature review, programme analysis, and field‐based observation, it proposes three operational approaches to the HDP nexus ...

Managing Emotion in Clinical Supervision Through Oller‐Vallejo's Model of Ego States
Journal of Psychiatric and Mental Health Nursing, Volume 33, Issue 5, Page 898-906, October 2026.ABSTRACT Aim This paper examines the value of Oller‐Vallejo's (2001) ego state model as a framework for understanding emotional dynamics in mental health nursing clinical supervision, and its integration with Proctor's (1986) model of supervision. Background Mental health nursing is characterised by high emotional demand, relational complexity and ...
