DESI Strong Lens Foundry. IV. Spectroscopic Confirmation of DESI Lens Candidates with VLT/MUSE

The Astrophysical Journal Supplement Series
We present integral field spectroscopic observations of 76 strong gravitational lens candidates identified with a residual neural network in the DESI Legacy Imaging Surveys, obtained with the Multi Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large ...

Looking at the Fundamental Plane through a Gravitational Lens [PDF]

The Astrophysical Journal, 2006
We consider the Fundamental Plane of elliptical galaxies lensed by the gravitational field of a massive deflector (typically, a cluster of galaxies). We show that the Fundamental Plane relation provides a straightforward measurement of the projected mass distribution of the lens with a typical accuracy of ~0.15 in the dimensionless column density kappa.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Multimodal multi-output ordinal regression for discovering gravitationally-lensed transients

Machine Learning: Science and Technology
Gravitational lenses are caused by massive astronomical objects that distort space-time, bending light. They can distort transient astrophysical events, such as supernovae (SN), which are the subject of extensive study.

Seeing ourselves in anatomy: Embedding equity, diversity, and inclusivity to transform learning in a UK BSc curriculum

Anatomical Sciences Education, EarlyView.
Abstract Embedding intersectional equity, diversity, and inclusion (EDI) in anatomy education is essential to reflect the growing diversity of student populations, support all learners, and prepare graduates for a more inclusive, socially responsive global workforce.

QUASI-ANALYTICAL METHOD FOR IMAGES CONSTRUCTION FROM GRAVITATIONAL LENSES

Odessa Astronomical Publications, 2016
One of the main problems in the study of system of equations of the gravitational lens, is the computation of coordinates from the known position of the source. In the process of computing finds the solution of equations with two unknowns. The problem is

The quadrupole gravitational lens

The Astrophysical Journal, 1987
An asymmetric lens made of a spherically symmetric galaxy and a quadrupole tidal part allows a very simple pictorial examination of the multiplicity and positions of the images, for any mass density profile. The lens equations can be reduced to one equation in one variable.

The gravitational lens equation [PDF]

, 2003
Questo lavoro di tesi discute approfondimenti teorici ed applicazioni cosmografiche dell'equazione della lente gravitazionale. Questa è l'equazione fondamentale del lensing gravitazionale, la teoria che descrive la deflessione della luce causata da campi gravitazionali.

Cross‐disciplinary integration: Information practices and a role for information scholars. An annual review of information science and technology paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Cross‐disciplinary research is a priority for many academic institutions, with a growing body of scholarship dedicated to studying the central practice of cross‐disciplinarity: integration, or the synthesis of knowledge, information, and data across disciplines and domains.

‘School is their whole world’: Teachers' perspectives on loneliness among children and adolescents from England and mainland China

British Educational Research Journal, EarlyView.
Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.
