A Framework for Obtaining Accurate Posteriors of Strong Gravitational Lensing Parameters with Flexible Priors and Implicit Likelihoods using Density Estimation

Ronan Legin, Yashar Hezaveh, Laurence Perreault-Levasseur +1

We report the application of implicit likelihood inference to the prediction of the macro-parameters of strong lensing systems with neural networks. This allows us to perform deep…

Posterior samples of source galaxies in strong gravitational lenses with score-based priors

Alexandre Adam, Adam Coogan, Nikolay Malkin +4

Inferring accurate posteriors for high-dimensional representations of the brightness of gravitationally-lensed sources is a major challenge, in part due to the difficulties of accu…

Population-Level Inference of Strong Gravitational Lenses with Neural Network-Based Selection Correction

Ronan Legin, Connor Stone, Yashar Hezaveh +1

A new generation of sky surveys is poised to provide unprecedented volumes of data containing hundreds of thousands of new strong lensing systems in the coming years. Convolutional…

Pixelated Reconstruction of Gravitational Lenses using Recurrent Inference Machines

Alexandre Adam, Laurence Perreault-Levasseur, Yashar Hezaveh

Modeling strong gravitational lenses in order to quantify the distortions in the images of background sources and to reconstruct the mass density in the foreground lenses has tradi…

Chaotic and Clumpy Galaxy Formation in an Extremely Massive Reionization-Era Halo

Justin S. Spilker, Christopher C. Hayward, Daniel P. Marrone +20

The SPT0311-58 system at z=6.900 is an extremely massive structure within the reionization epoch, and offers a chance to understand the formation of galaxies in an extreme peak in…
