Strong-Lensing Source Reconstruction with Denoising Diffusion Restoration Models
Konstantin Karchev, Noemi Anau Montel, Adam Coogan +1
Analysis of galaxy--galaxy strong lensing systems is strongly dependent on any prior assumptions made about the appearance of the source. Here we present a method of imposing a dat…
Detection is truncation: studying source populations with truncated marginal neural ratio estimation
Noemi Anau Montel, Christoph Weniger
Statistical inference of population parameters of astrophysical sources is challenging. It requires accounting for selection effects, which stem from the artificial separation betw…
Contrastive Neural Ratio Estimation for Simulation-based Inference
Benjamin Kurt Miller, Christoph Weniger, Patrick Forré
Likelihood-to-evidence ratio estimation is usually cast as either a binary (NRE-A) or a multiclass (NRE-B) classification task. In contrast to the binary classification framework,…
Snowmass Theory Frontier: Astrophysics and Cosmology
Daniel Green, Joshua T. Ruderman, Benjamin R. Safdi +84
We summarize progress made in theoretical astrophysics and cosmology over the past decade and areas of interest for the coming decade. This Report is prepared as the TF09 "Astrophy…
One never walks alone: the effect of the perturber population on subhalo measurements in strong gravitational lenses
Adam Coogan, Noemi Anau Montel, Konstantin Karchev +3
Analyses of extended arcs in strong gravitational lensing images to date have constrained the properties of dark matter by measuring the parameters of one or two individual subhalo…
Novel Constraints on Axions Produced in Pulsar Polar-Cap Cascades
Dion Noordhuis, Anirudh Prabhu, Samuel J. Witte +3
Axions can be copiously produced in localized regions of neutron star magnetospheres where the ambient plasma is unable to efficiently screen the induced electric field. As these a…
