Synergies between SALT and Herschel, Euclid & the SKA: strong gravitational lensing & galaxy evolution [PDF]

, 2015
Gravitational lensing has seen a surge of interest in the past few years. The handful of strong lensing systems known in the year 2000 has now been replaced with hundreds, thanks to innovative multi-wavelength selection, and there is an imminent prospect

Debris at the edge: sedimentological dynamics of Hintereisferner's evolving terminus and glacial forefield, Austrian Alps

Boreas, EarlyView.
The interaction between glaciers and the debris accumulating on their surfaces is critical as the Earth warms, with consequences for ice dynamics, hydrology and mass balance together with slope and sedimentary processes. Understanding this interaction is necessary since it influences ablation rates, sediment and meltwater pathways.

Heritage language learners' language availability and choice: A case study of primary school Persian learners in Australia

Foreign Language Annals, EarlyView.
Abstract This study investigates the factors influencing Persian language learning among heritage language learners in Sydney, Australia, with a particular focus on how formal and informal settings shape language choice and availability. The research employs a qualitative case study approach, incorporating data from student focus groups, semi ...

Precision MARS Mass Reconstruction of A2744: Synergizing the Largest Strong-lensing and Densest Weak-lensing Data Sets from JWST

The Astrophysical Journal
We 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 ...

Foreground biases in strong gravitational lensing

Journal of Cosmology and Astroparticle Physics
Abstract Strong gravitational lensing is a competitive tool to probe the dark matter and energy content of the Universe. However, significant uncertainties can arise from the choice of lens model, and in particular the parameterisation of the line of sight.

Pan‐Europe Revisited: Inter‐War Debates and the EU's Pursuit of Geopolitical Power

JCMS: Journal of Common Market Studies, EarlyView.
ABSTRACT The European Union's (EU) transformation from a peace project to an assertive geopolitical actor reflects enduring tensions in integration theory dating back to the inter‐war period. This paper develops a comparative framework distinguishing territorial integration logic, which emphasises bounded political communities and collective defence ...

Inferring Properties of Dark Galactic Halos Using Strongly Lensed Gravitational Waves

The Astrophysical Journal
Gravitational waves (GWs) can be deflected, similarly to electromagnetic (EM) waves, by massive objects through the phenomenon of gravitational lensing .

Cosmology using Strong Gravitational Lensing

The light we observe from distant astrophysical objects including supernovae and quasars allows us to determine large distances in terms of a cosmological model. Despite the success of the standard cosmological model in fitting the data, there remains no underlying explanation for the accelerated expansion and dark matter.
