Strong gravitational lensing by a charged Kiselev black hole [PDF]

The European Physical Journal C, 2017
We study the gravitational lensing scenario where the lens is a spherically symmetric charged black hole (BH) surrounded by quintessence matter. The null geodesic equations in the curved background of the black hole are derived. The resulting trajectory equation is solved analytically via perturbation and series methods for special choice of parameters

A Scalable Droplet Microfluidic Platform That Overcomes Large‐Cell Constraints for Long‐Term Plant Cell Culture and Embryogenesis Analysis

Advanced Science, EarlyView.
This work presents a large‐cell‐compatible droplet microfluidic platform that overcomes long‐standing barriers in plant cell culture by enabling high‐fidelity encapsulation, novel multilayer 3D droplet incubation for scalable long‐term culture, and support for the full developmental progression of large plant cells.

Probing the Evolution of Dusty Star-Forming Galaxies at the Cosmic Noon via Strong Gravitational Lensing

, 2023
The primary objective of this thesis is to explore the early stages of the evolution of Dusty Star-Forming Galaxies (DSFGs) by leveraging the physical phenomenon of strong gravitational lensing.

Star Formation under a Cosmic Microscope: Highly Magnified z = 11 Galaxy behind the Bullet Cluster

The Astrophysical Journal Letters
We present measurements of stellar population properties of a newly discovered, spectroscopically confirmed, $z=11.1{0}_{-0.26}^{+0.11}$ , gravitationally lensed galaxy, using JWST NIRSpec PRISM spectroscopy and NIRCam imaging.

Exploring the Possible Evolution of the Mass Density Power-law Index of Strong Gravitational Lenses with a Model-independent Method

The Astrophysical Journal, 2023
In this work, we adopt a cosmological model-independent approach for the first time to test the question of whether the mass density power-law index ( γ ) of strong gravitational lensing systems (SGLSs) evolves with redshift, and the joint light-curve ...

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 ...

Strong gravitational lensing and dark energy complementarity [PDF]

Physical Review D, 2004
In the search for the nature of dark energy most cosmological probes measure simple functions of the expansion rate. While powerful, these all involve roughly the same dependence on the dark energy equation of state parameters, with anticorrelation between its present value w_0 and time variation w_a.

An Opacity-free Test of the Cosmic Distance Duality Relation Using Strongly Lensed Gravitational-wave Signals with Space-based Detector Networks

The Astrophysical Journal
The cosmic distance duality relation (CDDR), expressed as d _L ( z ) = (1 +  z ) ^2 D _A ( z ), is a fundamental relation in modern cosmology. In this work, we apply a method to test the CDDR using simulated strongly lensed gravitational-wave (SLGW ...

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.
