Challenges and Insights in Growing Epitaxial FeSn Thin Films on GaAs(111) substrate Using Molecular Beam Epitaxy

Autor: Chatterjee, P., Nord, M., He, J., Meier, D., Brüne, C.

FeSn is a room-temperature antiferromagnet composed of alternating Fe3Sn kagome layers and honeycomb Sn layers. Its distinctive lattice allows the formation of linearly dispersing Dirac bands and topological flat bands in its electronic band structur

Neural Network Prediction of Strong Lensing Systems with Domain Adaptation and Uncertainty Quantification

Autor: Agarwal, Shrihan, Ćiprijanović, Aleksandra, Nord, Brian D.

Modeling strong gravitational lenses is computationally expensive for the complex data from modern and next-generation cosmic surveys. Deep learning has emerged as a promising approach for finding lenses and predicting lensing parameters, such as the

Population-level Dark Energy Constraints from Strong Gravitational Lensing using Simulation-Based Inference

Autor: Jarugula, Sreevani, Nord, Brian, Gandrakota, Abhijith, Ćiprijanović, Aleksandra

In this work, we present a scalable approach for inferring the dark energy equation-of-state parameter ($w$) from a population of strong gravitational lens images using Simulation-Based Inference (SBI). Strong gravitational lensing offers crucial ins

Domain Adaptive Graph Neural Networks for Constraining Cosmological Parameters Across Multiple Data Sets

Autor: Roncoli, Andrea, Ćiprijanović, Aleksandra, Voetberg, Maggie, Villaescusa-Navarro, Francisco, Nord, Brian

Deep learning models have been shown to outperform methods that rely on summary statistics, like the power spectrum, in extracting information from complex cosmological data sets. However, due to differences in the subgrid physics implementation and
